    OPINION OF THE COURT
    __________________
    SCIRICA, Circuit Judge.
    In 1979, an accident occurred at a nuclear power
    facility near Harrisburg, Pennsylvania, releasing radiation into
    the atmosphere and catapulting the name, "Three Mile Island,"
    into the national consciousness.      Sixteen years later, we are
    called on once again to consider the Three Mile Island accident
    2
    as we determine the appropriate standard of care for the
    operators of the facility.
    I.   Procedural History
    The accident at the Three Mile Island ("TMI") nuclear
    power facility occurred on March 28, 1979.      As a result,
    thousands of area residents and businesses filed suit against the
    owners and operators of the facility,0 alleging various injuries.0
    This case involves the consolidated claims of more than 2000
    plaintiffs for personal injuries allegedly caused by exposure to
    radiation released during the TMI accident.
    These cases began more than a decade ago, when
    plaintiffs filed damage actions in the Pennsylvania state courts
    and the Mississippi federal and state courts.0     After defendants
    removed the state cases to federal court, asserting federal
    jurisdiction under the Price-Anderson Act, we held that the Act
    created no federal cause of action and was not intended to confer
    jurisdiction on the federal courts.   See Kiick v. Metropolitan
    Edison Co., 
    784 F.2d 490
    (3d Cir. 1986); see also Stibitz v.
    0
    Defendants in this case were, at the time of the TMI accident,
    "the owners and operators of the nuclear facility, companies
    which had provided design, engineering or maintenance services,
    and those vendors of equipment or systems installed in the
    facility." In re TMI Litig. Cases Consol. II, 
    940 F.2d 832
    , 836
    (3d Cir. 1991), cert. denied, 
    503 U.S. 906
    (1992).
    0
    Defendants have settled non-personal injury claims brought by
    individuals, businesses, and non-profit organizations within a
    twenty-file mile radius of the TMI facility. See Stibitz v.
    General Pub. Util. Corp., 
    746 F.2d 993
    , 995 n.1 (3d Cir. 1984)
    (citing In Re Three Mile Island Litig., No. 79-0432 (M.D. Pa.
    Sept. 9, 1981)), cert. denied, 
    469 U.S. 1214
    (1985).
    0
    Counsel for plaintiffs concede they filed suit in Mississippi to
    take advantage of the state's six-year statute of limitations,
    instead of the two-year Pennsylvania statute.
    3
    General Pub. Utils. Corp., 
    746 F.2d 993
    (3d Cir. 1984), cert.
    denied, 
    469 U.S. 1214
    (1985).    The actions were remanded to the
    appropriate state courts.
    Subsequently, Congress enacted the Price-Anderson
    Amendments Act of 1988 ("1988 Amendments" or "Amendments Act"),
    Pub. L. No. 100-408, 102 Stat. 1066, which expressly created a
    federal cause of action for "public liability actions"0 and
    provided that such suits arose under the Price-Anderson Act.       42
    U.S.C. § 2014(hh) (1988).   The Amendments Act also provided for
    consolidation of such actions, including those already filed, in
    one federal district court.     
    Id. § 2210(n)(2).
      Accordingly,
    these personal injury actions were removed to federal court and
    consolidated in the Middle District of Pennsylvania.      We upheld
    the constitutionality of the retroactive application of the
    federal jurisdiction provisions of the Amendments Act and
    remanded the actions back to the district court.      In re TMI
    Litig. Cases Consol. II, 
    940 F.2d 832
    (3d Cir. 1991) ("TMI II"),
    cert. denied, 
    503 U.S. 906
    (1992).
    Contending they had not breached the duty of care,
    defendants then moved for summary judgment, which the district
    court denied.   In re TMI Litig. Cases Consol. II, No. 88-1452,
    slip op. at 36 (M.D. Pa. Feb. 18, 1994).     After holding that

    The Amendments Act defined a "public liability action" as "any
    suit asserting public liability." 42 U.S.C. § 2014(hh) (1988).
    "[P]ublic liability" was defined as "any legal liability arising
    out of or resulting from a nuclear incident or precautionary
    evacuation," except for certain claims covered by workers'
    compensation, incurred in wartime, or that involve the licensed
    property where the nuclear incident occurs. 
    Id. §2014(w). 4
    federal law determines the standard of care and preempts state
    tort law, 
    id. at 23,
    the district court found the standard of
    care was set by the federal regulations: 1) prescribing the
    maximum permissible levels of human exposure to radiation0 and 2)
    requiring radiation releases to be "as low as is reasonably
    achievable," which is known as the "ALARA" principle.0    
    Id. at 28-29.
       The court held that each plaintiff must prove individual
    exposure to radiation in order to establish causation, but not to
    establish a breach of the duty of care.   
    Id. at 30-31.
    Upon defendants' motion, the district court certified
    for interlocutory appeal the duty of care and causation issues:
    1)   Whether 10 C.F.R. §§ 20.105 and 20.106, and not
    ALARA, constitute the standard of care to be
    applied in these actions;
    2)   Whether a particular Plaintiff's level of exposure
    to radiation or radioactive effluents relates
    solely to causation or also to the duty owed by
    Defendants.
    In re TMI Litig. Cases Consol. II, No. 88-1452 (M.D. Pa. July 13,
    1994).0   We granted the petition for interlocutory appeal.
    0
    See 10 C.F.R. §§ 20.105, 20.106 (1979). For a discussion of
    these regulations, see infra part III.B.1.
    0
    "ALARA" is defined to mean "as low as is reasonably achievable
    taking into account the state of technology, and the economics of
    improvements in relation to benefits to the public health and
    safety, and other societal and socioeconomic considerations, and
    in relation to the utilization of atomic energy in the public
    interest." 10 C.F.R. § 20.1(c). The term appears in several
    sections of the C.F.R., including § 20.1(c), §50.34a, and §
    50.36a. For a further discussion of the term, see infra part
    III.B.
    0
    The district court also certified a question regarding punitive
    damages, which we discuss in a separate opinion. See In Re: TMI,
    cite. We resolve other issues concerning the applicable statute
    of limitations in a third opinion. See In Re: TMI, cite.
    5
    The district court had jurisdiction under 42 U.S.C.
    §2210(n)(2) (1988).    We have jurisdiction under 28 U.S.C.
    §1292(b) (1988) and exercise plenary review over the legal
    questions certified.    See Buzzard v. Roadrunner Trucking, Inc.,
    
    966 F.2d 777
    , 779 (3d Cir. 1992).
    II.    Preemption
    Initially, we must address the district court's
    decision that federal law determines the standard of care,
    preempting state tort law.       See In re TMI Litig. Cases Consol.
    II, No. 88-1452, slip op. at 23 (M.D. Pa. Feb. 18, 1994).        The
    district court essentially relied on our holding in TMI II, 
    940 F.2d 832
    , 859 (3d Cir. 1991), cert. denied, 
    503 U.S. 906
    (1992),
    and decisions following it.0      See In re TMI Litig. Cases Consol.
    II, No. 88-1452, slip op. at 15-23 (M.D. Pa. Feb. 18, 1994).           But
    plaintiffs contend that TMI II did not resolve this issue.
    Under the 1988 Amendments, the applicable law for
    "public liability actions" is "the law of the State in which the
    nuclear incident involved occurs, unless such law is
    inconsistent" with federal law.         42 U.S.C. § 2014(hh) (1988).
    Thus, Pennsylvania tort law would control here, unless
    inconsistent with federal law.      But TMI II decided this issue by
    preempting state tort law on the standard of care.
    0
    See, e.g., O'Conner v. Commonwealth Edison Co., 
    13 F.3d 1090
    ,
    1105 (7th Cir.) ("[W]e agree with the Third Circuit in TMI that
    it is clear . . . that state regulation of nuclear safety,
    through either legislation or negligence actions, is preempted by
    federal law."), cert. denied, 
    114 S. Ct. 2711
    (1994).
    6
    In TMI II, we considered the constitutionality of the
    1988 Amendments, specifically, whether they improperly conferred
    "arising under" 
    jurisdiction. 940 F.2d at 848-49
    .   Examining the
    Amendments Act's "federal components," we found federal
    preemption of state tort law on the applicable standard of care.
    See 
    id. at 858
    ("Two Supreme Court cases indicate that the duty
    the defendants owe the plaintiffs in tort is dictated by federal
    law."); 
    id. at 859
    ("Permitting the states to apply their own
    nuclear regulatory standards, in the form of the duty owed by
    nuclear defendants in tort, would, however, 'frustrate the
    objectives of federal law.'") (citation omitted); 
    id. ("Under Pacific
    Gas & Electric Co., states are preempted from imposing a
    non-federal duty in tort, because any state duty would infringe
    upon pervasive federal regulation in the field of nuclear safety,
    and thus would conflict with federal law.").    Thus, TMI II
    definitively resolved the issue whether federal law preempts
    state tort law on the standard of care.
    But we also said, "Consequently the plaintiffs' rights
    will necessarily be determined, in part, by reference to federal
    law, namely the federal statutes and regulations governing the
    safety and operation of nuclear facilities."    
    Id. at 860.
    Plaintiffs contend that, by using the term "in part," "this Court
    left open the question of whether the applicable duty of care is
    exclusively federal."   Appellees' Br. at 37.   We cannot agree.
    Because we held that federal law preempted state law on the duty
    of care, plaintiffs' rights had to be determined, at least in
    part, by federal law.   We did not address whether federal law
    7
    also controlled other aspects of plaintiffs' claims, such as
    causation and damages, because they were not at issue.     TMI II
    controls, and federal law determines the standard of care and
    preempts state tort law.     See also O'Conner v. Commonwealth
    Edison Co., 
    13 F.3d 1090
    , 1105 (7th Cir.) (citing TMI II)
    (holding state law on the duty of care preempted in tort suits
    involving nuclear safety), cert. denied, 
    114 S. Ct. 2711
    (1994).
    III.   Statutory and Regulatory History
    Although it is clear that federal law governs the
    standard of care for tort claims arising from nuclear accidents,
    it is more difficult to discern the precise contours of that
    federal duty.    The question appears to be one of first impression
    for a federal appellate court.0     Accordingly, we will examine the
    language of the relevant statutes and regulations, and the
    underlying history and policies.
    A.   Statutes
    Nearly a half century ago, Congress initiated its
    regulation of nuclear power through the enactment of the Atomic
    Energy Act of 1946, Pub. L. No. 79-585, 60 Stat. 755.     The Act
    was designed to establish an industry to generate inexpensive
    electrical power, transforming "atomic power into a source of
    energy" and turning "swords into plowshares."     Pacific Gas &
    Elec. Co. v. State Energy Resources Conservation & Dev. Comm'n,
    
    461 U.S. 190
    , 193 (1983).
    0
    Some federal district courts and state courts have considered
    this issue, with varying results. See infra part IV.C.
    8
    Although the 1946 Act designated the nuclear industry a
    government monopoly, Congress later decided to permit private
    sector involvement.   See Atomic Energy Act of 1954, Pub. L. No.
    83-703, 68 Stat. 919.    The 1954 Act "grew out of Congress'
    determination that the national interest would be best served if
    the Government encouraged the private sector to become involved
    in the development of atomic energy for peaceful purposes under a
    program of federal regulation and licensing."   Pacific Gas &
    
    Elec., 461 U.S. at 206-07
    (citing H.R. Rep. No. 2181, 83d Cong.,
    2d Sess. 1-11 (1954)).
    Nevertheless, because of the unique nature of this form
    of energy production, the fledgling nuclear industry faced many
    problems, particularly:
    the risk of potentially vast liability in the
    event of a nuclear accident of a sizable
    magnitude . . . . [W]hile repeatedly
    stressing that the risk of a major nuclear
    accident was extremely remote, spokesmen for
    the private sector informed Congress that
    they would be forced to withdraw from the
    field if their liability were not limited by
    appropriate legislation.
    Duke Power Co. v. Carolina Envtl. Study Group, Inc., 
    438 U.S. 59
    ,
    64 (1978) (citations omitted).
    In response, Congress enacted the Price-Anderson Act
    "to protect the public and to encourage the development of the
    atomic energy industry."   Pub. L. No. 85-256, § 1, 71 Stat. 576
    (1957).   The Act limited the potential civil liability of nuclear
    plant operators and provided federal funds to help pay damages
    caused by nuclear accidents.   
    Id. Congress has
    amended the
    Price-Anderson Act three times, most recently in 1988,
    9
    "provid[ing] a mechanism whereby the federal government can
    continue to encourage private sector participation in the
    beneficial uses of nuclear materials."    In re TMI Litig. Cases
    Consol. II, 
    940 F.2d 832
    , 853 (3d Cir. 1991) ("TMI II") (citing
    S. Rep. No. 218, 100th Cong., 2d Sess. 4, reprinted in 1988
    U.S.C.C.A.N. 1476, 1479), cert. denied, 
    503 U.S. 906
    (1992).
    Throughout this period, Congress repeatedly sought to
    encourage the development of the nuclear power industry.    Yet,
    Congress has continued the "dual regulation of nuclear-powered
    electricity generation: the Federal Government maintains complete
    control of the safety and 'nuclear' aspects of energy generation;
    the States exercise their traditional authority over the need for
    additional generating capacity, the type of generating facilities
    to be licensed, land use, ratemaking, and the like."    Pacific Gas
    & 
    Elec., 461 U.S. at 211-12
    (footnote omitted).
    B.   Regulations
    Volume 10 of the Code of Federal Regulations (1979)0
    governs energy matters, and its first chapter regulates the
    Nuclear Regulatory Commission ("NRC").0   Parts 20 and 50 of
    Chapter 1 are the relevant sections.
    1.   10 C.F.R. Part 20

    In this case, the relevant federal regulations were those in
    place at the time of the TMI accident in 1979. Unless otherwise
    noted, all citations to the Code of Federal Regulations refer to
    the 1979 version.

    See infra note 20.
    10
    Part 20 of 10 C.F.R. ch. 1 outlines "Standards for
    Protection Against Radiation."   Under the "General Provisions" of
    Part 20, § 20.1(c) provides a statement of the ALARA principle:
    In accordance with recommendations of
    the Federal Radiation Council, approved by
    the President, persons engaged in activities
    under licenses issued by the Nuclear
    Regulatory Commission . . . should, in
    addition to complying with the requirements
    set forth in this part, make every reasonable
    effort to maintain radiation exposures, and
    releases of radioactive materials in
    effluents to unrestricted areas, as low as is
    reasonably achievable. The term "as low as
    is reasonably achievable" means as low as is
    reasonably achievable taking into account the
    state of technology, and the economics of
    improvements in relation to benefits to the
    public health and safety, and other societal
    and socioeconomic considerations, and in
    relation to the utilization of atomic energy
    in the public interest.
    (emphasis added).
    Immediately following the "General Provisions" of Part
    20 is a subpart covering "Permissible Doses, Levels, and
    Concentrations," which regulates exposures of radiation to
    persons on the property of a nuclear facility, see 10 C.F.R.
    §§20.101-.104,0 as well as those off premises, see 
    id. § 20.105-
    .106.   The latter regulations, governing "unrestricted areas,"0
    are relevant here because plaintiffs were outside the TMI
    premises when the alleged radiation exposures occurred.
    0
    These regulations apply to persons in "restricted areas," which
    are defined as "any area access to which is controlled by the
    licensee for purposes of protection of individuals from exposure
    to radiation and radioactive materials." 10 C.F.R. §20.3(a)(14).
    0
    An "unrestricted area" is "any area access to which is not
    controlled by the licensee for purposes of protection of
    individuals from exposure to radiation and radioactive materials,
    and any area used for residential quarters." 
    Id. § 20.1(a)(17).
    11
    Section 20.105 sets the "[p]ermissible levels of
    radiation in unrestricted areas," i.e., outside the TMI
    facility's boundaries.   It mandates that the NRC approve license
    applications if the applicant shows its plan is not likely to
    cause anyone to receive radiation in excess of 0.5 rem0 per year.
    § 20.105(a).    In subsection (b), the regulation provides that
    except as authorized by the NRC, no licensee shall cause
    "[r]adiation levels which, if an individual were continually
    present in the area, could result in his receiving a dose in
    excess of" two millirems in any hour or 100 millirems in any
    week.   The parties dispute whether the § 20.105 standard
    governing off-site exposure was violated during or after the TMI
    accident.
    While § 20.105 defines the levels of radiation
    permitted in unrestricted areas, § 20.106 defines the levels of
    radioactivity permitted in liquid or airborne effluents released
    off premises.    It provides that licensees "shall not possess,
    use, or transfer licensed material so as to release to an
    unrestricted area radioactive material in concentrations which
    exceed the limits specified in Appendix 'B', Table II of this
    part, except as authorized . . . ."    Appendix B then lists more
    0
    Doses of radiation of different ionizations are expressed in
    "rems," a unit of measurement that "embodies both the magnitude
    of the dose and its biological effectiveness." U.S. Dep't of
    Commerce, Permissible Dose From External Sources of Ionizing
    Radiation: National Bureau of Standards Handbook 59 30-31 (1954);
    see also 10 C.F.R. § 20.4(c) (defining rem as "a measure of the
    dose of any ionizing radiation to body tissues in terms of its
    estimated biological effect relative to a dose of one roentgen
    (r) of X-rays").
    12
    than 100 isotopes of almost 100 radioactive elements and provides
    the maximum permissible level of releases.   Defendants admit that
    the radiation levels at the boundary of the TMI facility exceeded
    the § 20.106 standards after the 1979 accident.0   Nevertheless,
    they claim that no plaintiff was in an area exposed to the
    impermissible levels.
    2.   10 C.F.R. Part 50
    In order to understand the ALARA concept and whether it
    forms part of the standard of care, it is necessary to examine
    Part 50 of 10 C.F.R. ch. 1, which covers the "Domestic Licensing
    of Production and Utilization Facilities."   Section 50.34a(a)

    and other societal and socioeconomic
    considerations, and in relation to the
    utilization of atomic energy in the public
    interest. The guides set out in Appendix I
    provide numerical guidance on design
    objectives for light-water-cooled nuclear
    power reactors to meet the requirements that
    radioactive material in effluents released to
    unrestricted areas be kept as low as is
    reasonably achievable. These numerical
    guides for design objectives and limiting
    conditions for operation are not to be
    construed as radiation protection standards.
    Section 50.36a lists technical specifications "to keep
    releases of radioactive materials to unrestricted areas during
    normal reactor operations, including expected operational
    occurrences, as low as is reasonably achievable."   § 50.36a(a).
    Subsection (b) provides in part:
    Experience with the design, construction and
    operation of nuclear power reactors indicates
    that compliance with the technical
    specifications described in this section will
    keep average annual releases of radioactive
    material in effluents at small percentages of
    the limits specified in § 20.106 of this
    chapter and in the operating license. At the
    same time, the licensee is permitted the
    flexibility of operation, compatible with
    considerations of health and safety, to
    assure that the public is provided a
    dependable source of power even under unusual
    operating conditions which may temporarily
    result in releases higher than such small
    percentages, but still within the limits
    specified in § 20.106 of this chapter and the
    operating license. It is expected that in
    using this operational flexibility under
    unusual operating conditions, the licensee
    will exert his best efforts to keep levels of
    radioactive material in effluents as low as
    practicable. The guides set out in Appendix
    I provide numerical guidance on limiting
    conditions for light-water-cooled nuclear
    power reactors to meet the requirement that
    radioactive materials in effluents released
    14
    to unrestricted areas be kept as low as is
    reasonably achievable.
    Appendix I to Part 50, referenced in §§ 50.34a and
    50.36a, then provides:
    numerical guides for design objectives and
    limiting conditions for operation to assist
    applicants for, and holders of, licenses for
    light-water-cooled nuclear power reactors in
    meeting the requirements of §§ 50.34a and
    50.36a that radioactive material in effluents
    released from those facilities to
    unrestricted areas be kept as low as is
    reasonably achievable. Design objectives and
    limiting conditions for operation conforming
    to the guidelines of this Appendix shall be
    deemed a conclusive showing of compliance
    with the "as low as is reasonably achievable"
    requirements of 10 C.F.R. 50.34a and 50.36a.
    Design objectives and limiting conditions for
    operations differing from the guidelines may
    also be used, subject to a case-by-case
    showing of a sufficient basis for the
    findings of "as low as is reasonably
    achievable" required by §§ 50.34a and 50.36a.
    The Part 50 Appendix I standards, governing permissible
    radiation releases, were set far below the levels permitted by
    §§20.105 and 20.106.   The parties apparently agree that a plant
    operator's compliance with the Appendix I guidelines will shield
    it from liability.   But they disagree on whether an operator's
    compliance with the higher emission levels permitted by §§ 20.105
    and 20.106 also suffices to protect it from liability.
    IV.   Duty of Care
    A fundamental disagreement in this case centers on
    which of the federal regulations, or combination thereof, sets
    the applicable standard of care for nuclear power defendants.
    Plaintiffs contend the ALARA regulations articulate the duty owed
    15
    by defendants, while defendants claim that 10 C.F.R. §§ 20.105
    and 20.106 govern.
    The district court held that a "tri-level scheme,"
    combining the ALARA regulations and 10 C.F.R. § 20.106,
    constituted the applicable standard of care.     In re TMI Litig.
    Cases Consol. II, No. 88-1452, slip op. at 28 (M.D. Pa. Feb. 18,
    1994).   The court found that nuclear power defendants could not
    be held liable for radiation emissions below the minimum levels
    set by Appendix I of 10 C.F.R. part 50.   
    Id. The court
    continued:
    [I]f Plaintiffs can prove that Defendants'
    emissions exceeded those levels set out in
    §20.106, Defendants will have violated the
    relevant standard of care and will be held
    liable, provided Plaintiffs are also able to
    satisfy the causation and harm elements of
    their claims. If the evidence indicates that
    emissions levels fall between the two
    standards, Defendants may be held liable if
    Plaintiff can prove (along with the causation
    and harm prongs) that Defendants did not use
    their best efforts to reduce radioactive
    emissions.
    
    Id. at 29.
       Both plaintiffs and defendants challenge this holding
    and, as we have noted, the district court certified whether 10
    C.F.R. §§ 20.105 and 20.106, and not ALARA, constitute the
    applicable standard of care.
    A.   Development of Radiation Protection Standards
    We begin our analysis with a review of 10 C.F.R.
    §§20.105 and 20.106.   In 1957, the Atomic Energy Commission
    ("AEC") issued regulations "to establish standards for the
    protection of [nuclear plant] licensees, their employees and the
    general public against radiation hazards."      25 Fed. Reg. 8595,
    16
    8595 (1960).   The dosage for persons in "unrestricted areas" (the
    public) was limited to ten percent of that permitted for persons
    in "restricted areas" (plant employees).    22 Fed. Reg. 548, 549
    (1957).   The preface to the regulation explained, "It is believed
    that the standards incorporated in these regulations provide, in
    accordance with present knowledge, a very substantial margin of
    safety for exposed individuals.    It is believed also that the
    standards are practical from the standpoint of licensees."     
    Id. In 1960,
    the AEC substantially revised these
    regulations.   Upon recommendations from the Federal Radiation
    Council0 and the National Committee on Radiation Protection,0 the
    AEC promulgated §§ 20.105 and 20.106, setting 0.5 rem as the
    maximum yearly radiation exposure allowed for the general
    0
    A 1959 amendment to the Atomic Energy Act created the Federal
    Radiation Council and ordered it to "consult qualified scientists
    and experts in radiation matters" in order "to advise the
    President with respect to radiation matters, directly or
    indirectly affecting health, including guidance for all Federal
    agencies in the formulation of radiation standards . . . ." Pub.
    L. No. 86-373, 73 Stat. 688, 690 (1959). Upon the establishment
    of the Environmental Protection Agency in 1970, the functions of
    the council were transferred to the EPA, and it was abolished.
    See Reorganization Plan No. 3 of 1970, 84 Stat. 2086, 2088-89
    (1970); 35 Fed. Reg. 15623, 15624, 15626 (1970).

    The National Bureau of Standards sponsored the creation of the
    Advisory Committee on X-ray and Radium Protection in 1929. In
    1954, after the advent of atomic energy, the committee changed
    its name to the National Committee on Radiation Protection. See
    U.S. Dep't of Commerce, Permissible Dose From External Sources of
    Ionizing Radiation: National Bureau of Standards Handbook 59 iii
    (1954). In 1964, Congress transformed the committee into the
    National Council on Radiation Protection and Measurements and
    charged it with developing information and recommendations
    concerning radiation protection. Pub. L. No. 88-376, §§ 3, 16,
    78 Stat. 320, 321, 324 (1964) (codified at 36 U.S.C. §§ 4501-17
    (1988)).

    public.0   25 Fed. Reg. 8595, 8595 (1960).   The AEC concluded the
    new regulations represented "an appropriate regulatory basis for
    protection of the health and safety of employees and the public
    without imposing undue burdens upon licensed users of radioactive
    material."    
    Id. The AEC
    stated:
    Recommended limits on exposure, based
    upon extensive scientific and technical
    investigation and upon years of experience
    with the practical problems of radiation
    protection, represent a consensus as to the
    measures generally desirable to provide
    appropriate degrees of safety in the
    situations to which these measures apply.
    While the numerical values for exposure
    limits established in this regulation provide
    a conservative standard of safety, the nature
    of the problem is such that lower exposure
    limits would be used if considered practical.
    At the same time, if there were sufficient
    reason, the use of considerably higher
    exposure limits in this regulation would not
    have been considered to result in excessive
    hazards.
    
    Id. Four years
    later, in 1964, the AEC amended § 20.106 (and the
    Appendix B levels to which § 20.106 refers) to incorporate new
    recommendations made by the Federal Radiation Council to the
    President.    See 29 Fed. Reg. 14434, 14434 (1964); see also 28
    Fed. Reg. 10170, 10171 (1963).     The new limitations were designed
    0
    In 1991, the NRC issued new regulations reducing the annual
    permissible exposure rate for the public to 0.1 rem per
    individual -- down from the 0.5 rem standard that had existed for
    more than three decades. See 10 C.F.R. § 20.1301 (1995); 56 Fed.
    Reg. 23398 (1991). The 1991 regulations adopted recommendations
    made by the International Commission on Radiological Protection
    in 1977. See Leonard S. Greenberger, NRC Amends Radiation
    Protection Requirements, Pub. Util. Fortnightly, Jan. 15, 1991,
    at 54, 54. Even with these reductions, the permissible exposure
    rate for the public in the United States remained higher than the
    .05 rem public exposure limit in Great Britain and the .03 rem
    limit in Germany. See 
    id. 18 "to
    protect individuals in the general population from exposure
    to radiation as a result of intake of radioactivity through air
    and water."     
    Id. These regulations
    remained in effect at the
    time of the TMI accident in 1979.0
    B.   Development of ALARA
    A decade after promulgation of §§ 20.105 and 20.106,
    the Atomic Energy Commission amended 10 C.F.R. parts 20 and 50 to
    incorporate an early version of the ALARA rule.      35 Fed. Reg.
    18385 (1970).    The AEC noted that a general purpose of its
    regulatory policy was to ensure "radiation exposures to the
    public should be kept as low as practicable."      
    Id. at 18386-87
    (promulgating §§ 20.1(c)).     The AEC then promulgated two sections
    in Part 50 to further this policy.      First, it added § 50.34a to
    ensure that applicants for nuclear license permits identified
    "the design objectives, and the means to be employed," for
    keeping levels of radioactive material in effluents as low as
    practicable.    Second, it enacted § 50.36a to require that
    licenses issued to nuclear operators include technical
    specifications to keep releases of radiation as low as
    practicable.    
    Id. at 18387-88.
              In 1975, these regulations were modified in two ways.
    First, the Nuclear Regulatory Commission, the statutory successor
    to the Atomic Energy Commission,0 added Appendix I0 to define the

    The regulations have been significantly modified since 1979. See
    generally 10 C.F.R. chs. 20, 50 (1995).

    in doing so the agency emphasized the criteria were not to be
    considered "radiation protection standards."         40 Fed. Reg. 19439,
    19439 (1975).     Second, the NRC replaced the term "as low as
    practicable" with "as low as reasonably achievable"; the former
    term was deemed "less precise" and already had been replaced by
    the International Commission on Radiological Protection
    ("ICRP").0    
    Id. at 58847.
                                  C.   Case Law
    In framing their arguments, both plaintiffs and
    defendants rely on decisional law, although we find the
    applicable case law inconclusive.        Plaintiffs, as well as the
    district court, cite Crawford v. National Lead Co., 
    784 F. Supp. 439
    (S.D. Ohio 1989).     In Crawford, neighbors of a uranium
    production plant sued over the plant's discharge of uranium into
    the atmosphere and a nearby river.        In denying defendants' motion
    for summary judgment, the district court found sufficient
    evidence of state law violations.        The court decided there was
    "no conflict between state tort law and the federal interests at
    issue here," because it found defendants had violated pertinent
    federal regulations, including ALARA.

    opinion cites favorably to the ALARA requirement, the court
    conducted a cursory review of the federal regulatory scheme and
    discussed the federal regulations only to demonstrate the absence
    of a conflict with state law.
    For their part, defendants cite Akins v. Sacramento
    Municipal Utililty District, 
    8 Cal. Rptr. 2d 785
    (Cal. Ct. App.
    1992), dismissed, 
    868 P.2d 905
    (Cal. 1994), a suit alleging
    excessive discharges of radioactive materials from the Rancho
    Seco Nuclear Power Plant.   The court noted that Appendix I and
    the ALARA standard in § 50.36a(b) were not radiation protection
    standards, see 
    id. at 794
    n.7, and affirmed the grant of
    defendants' motion for summary judgment.   The court held that the
    evidence established that "no one, including any of the
    plaintiffs, was actually exposed to dosages of radiation which
    were more than a small fraction of the NRC and EPA standards."
    
    Id. at 814.
    Defendants also cite several cases involving nuclear
    plant employees suing over alleged radiation exposures.    In these
    cases, courts routinely applied the parallel federal regulations
    governing persons in "restricted areas," 
    see supra
    note 12, but
    did not apply ALARA.   For example, in O'Conner v. Commonwealth
    Edison Co., 
    748 F. Supp. 672
    (C.D. Ill. 1990), aff'd, 
    13 F.3d 1090
    , 1103-05 (7th Cir.), cert. denied, 
    114 S. Ct. 2711
    (1994), a
    nuclear plant worker filed suit against the operator of the
    plant, alleging injuries from radiation exposure.   After an
    analysis of the federal regulatory scheme, the district court
    held that the limits set in 10 C.F.R. § 20.101 (applicable to
    21
    workers on site, just as §§ 20.105 and 20.106 apply to persons
    off site) supplied the duty of care.   The court, without
    mentioning the ALARA regulations, stated:
    These federal permissible dose limits
    are based upon the national and international
    scientific consensus as to the hypothetical
    risk from exposure to low occupational levels
    of ionizing radiation. . . .
    In determining the likelihood of the
    injury from radiation, this Court believes
    that it should give deference to the
    administrative regulations which are the
    result of the agency's applied expertise.

    Similarly, in Hennessy v. Commonwealth Edison Co., 
    764 F. Supp. 495
    (N.D. Ill. 1991), a nuclear plant worker received a
    routine medical exam and learned he had been contaminated with a
    radioactive material, but at a level below that permitted by 10
    C.F.R. § 20.103 (setting permissible levels for plant workers).
    Although he claimed no physical injury from the exposure, he sued
    under strict liability and for battery and negligent infliction
    of emotional distress.   The district court granted summary
    judgment to defendants, but stated in dicta that ALARA might have

    The Restatement (Second) of Torts expressly provides that, in
    certain situations, a "court may adopt as the standard of conduct
    of a reasonable man the requirements of a legislative enactment
    or an administrative regulation." Restatement (Second) of Torts
    § 286 (1965); see also W. Page Keeton et al., Prosser and Keeton
    on the Law of Torts § 36, at 220 (5th ed. 1984) (citing numerous
    cases) ("When a statute provides that under certain circumstances
    particular acts shall be done or not done, it may be interpreted
    as fixing a standard for all members of the community, from which
    it is negligence to deviate. The same may be true of . . .
    regulations of administrative bodies."). We believe it
    appropriate to adopt §§ 20.105 and 20.106 as the standard of
    conduct in this situation. As one commentator noted:
    The element of breach of duty is a
    critical issue in the adjudication of
    radiation cases and one that presents
    significant problems. The problems arise out
    of the necessity to create or adopt a legally
    sufficient standard by which to measure
    breach. The answer to the problem in this
    highly regulated area should be
    straightforward: compliance or noncompliance
    with applicable government safety standards
    provides an excellent measure of breach.

    relevant regulatory bodies -- the Federal Radiation Council, EPA,
    AEC, and NRC -- on the appropriate levels of radiation to which
    the general public may be exposed.0   See, e.g., 25 Fed. Reg.
    8595, 8595 (1960) (Sections 20.105 and 20.106 "provide an
    appropriate regulatory basis for protection of the health and
    safety of employees and the public without imposing undue burdens
    upon licensed users of radioactive material.").    In fact, the
    heading for this category of regulations is "Permissible Doses,
    Levels, and Concentrations," and the relevant regulations are
    phrased in terms of the maximum levels of radiation that may be
    released.   See 10 C.F.R. §§ 20.101-.108.
    Although plaintiffs assert that § 20.105 applies
    exclusively to nuclear plant employees, we disagree.    Part 20 of
    10 C.F.R. ch. 1 is divided into separate sections governing
    permissible dose limits for individuals in "restricted areas,"
    see §§ 20.101, 20.103, and "unrestricted areas," see §§ 20.105,
    20.106.   The definitions of "restricted" and "unrestricted
    areas"0 demonstrate that the C.F.R. sections governing persons in
    "unrestricted areas" were intended to cover persons outside a
    nuclear plant's boundaries, i.e., the general public.    The case
    law, while differing over the use of the ALARA standard, appears
    to have uniformly accepted this meaning.    See, e.g., 
    Akins, 8 Cal. Rptr. 2d at 794
    ; 
    Crawford, 784 F. Supp. at 447

    As we have noted, these agencies have promulgated different
    standards regarding radiation levels for workers at nuclear power
    plants. See 10 C.F.R. §§ 20.101-.104; see 
    also supra
    part
    III.B.1.

    Plaintiffs also contend that the Part 20 dose standards
    govern only during normal operating conditions, not during
    accidents.    But neither the language of the regulations nor its
    history suggests this interpretation.         Instead, we believe the
    Part 20 dose limits were intended as the maximum permitted under
    all conditions, accident and normal operations alike.         The NRC
    itself has adopted this interpretation, stating it "believes that
    the dose limits for normal operation should remain the primary
    guidelines in emergencies," 56 Fed. Reg. 23360, 23365 (1991), and
    we believe this agency interpretation is entitled to some
    deference.    See Chevron, U.S.A. Inc. v. Natural Resources Defense
    Council, Inc., 
    467 U.S. 837
    , 844 (1984).
    For many of the same reasons that we adopt §§ 20.105
    and 20.106 as the applicable standard of care, we reject the
    ALARA regulations as part of that standard.         First, we believe
    the language of the ALARA regulations compels this result.
    Section 50.34a explicitly provides:
    The guides set out in Appendix I provide
    numerical guidance on design objectives for
    light-water-cooled nuclear power reactors to
    meet the requirements that radioactive
    material in effluents released to
    unrestricted areas be kept as low as is
    reasonably achievable. These numerical
    guides for design objectives and limiting
    conditions for operation are not to be
    construed as radiation protection standards.
    (emphasis added).    The regulation could not be more clear.         The
    guidelines that satisfy ALARA "are not to be construed as
    radiation protection standards."       Id.0   In fact, § 50.36a(b)
    0
    We recognize some ambiguity in the regulatory history on whether
    ALARA is intended to serve as a radiation protection standard,
    26
    expressly permits continued operation of a nuclear plant if
    radiation releases rise above the Appendix I ALARA levels so long
    as they remain "within the limits specified in § 20.106."0
    Second, the regulation that incorporated the Appendix I
    guidelines (that contains ALARA language) explained that the
    "radiation protection standards" of 10 C.F.R. Part 20 continued
    to protect public health:
    It should be emphasized that the
    Appendix I guides as here adopted by the
    Commission are not radiation protection
    standards. The numerical guides of Appendix
    I which we announce today are a quantitative
    expression of the meaning of the requirement
    that radioactive material in effluents
    released to unrestricted areas . . . be kept
    "as low as practicable."
    The Commission's radiation protection
    standards, which are based on recommendations
    of the Federal Radiation Council (FRC) as
    approved by the President, are contained in
    10 CFR Part 20, "Standards for Protection
    Against Radiation," and remain unchanged by
    this Commission decision. . . . [T]hese FRC
    standards which have been previously adopted
    give appropriate consideration to the overall
    requirements of health protection and the
    see, e.g., 40 Fed. Reg. 19439, 19440 (1975); 35 Fed. Reg. 18385,
    18386 (1970); Staff Report of the Federal Radiation Council,
    Background Material for the Development of Radiation Protection
    Standards, May 13, 1960, at 26; Staff Report of the Federal
    Radiation Council, Background Material for the Development of
    Radiation Protection Standards, Sept. 1961, at 1, but we are
    unpersuaded by these ambiguous regulatory statements.
    0
    In 1987, President Reagan approved an EPA memorandum that
    revised radiation protection standards for nuclear plant
    employees. That EPA memorandum noted that "[t]he recommendation
    that Federal agencies, through their regulations, operational
    procedures and other appropriate means, maintain doses ALARA is
    not intended to express, and therefore should not be interpreted
    as expressing, a view whether the ALARA concept should constitute
    a duty of care in tort litigation." 52 Fed. Reg. 2822, 2826
    (1987).
    27
    beneficial use of radiation and atomic
    energy. The Commission believes that the
    record clearly indicates that any biological
    effects that might occur at the low levels of
    these standards have such low probability of
    occurrence that they would escape detection
    by present-day methods of observation and
    measurement.
    40 Fed. Reg. 19439, 19439-40 (1975).
    Furthermore, as we have noted, the Atomic Energy
    Commission adopted the reasoning of the Federal Radiation Council
    in promulgating the ALARA regulations.   The Federal Radiation
    Council stipulated it had intended that federal agencies would
    determine the reasonableness of radiation releases.   See Staff
    Report of the Federal Radiation Council, Background Material for
    the Development of Radiation Protection Standards, May 13, 1960,
    at 38 ("The Federal agencies should apply these Radiation
    Protection Guides with judgment and discretion, to assure that
    reasonable probability is achieved in the attainment of the
    desired goal of protecting man from the undesirable effects of
    radiation.   The Guides may be exceeded only after the Federal
    agency having jurisdiction over the matter has carefully
    considered the reason for doing so . . . ."); Staff Report of the
    Federal Radiation Council, Background Material for the
    Development of Radiation Protection Standards, Sept. 1961, at 2
    ("[N]o exposure to radiation should be permitted unless . . .
    [t]he various benefits to be expected as a result of the
    exposure, as evaluated by the appropriate responsible group, must
    outweigh the potential hazard or risk . . . .").
    28
    Finally, ALARA is defined as meaning "as low as is
    reasonably achievable taking into account the state of
    technology, and the economics of improvements in relation to
    benefits to the public health and safety, and other societal and
    socioeconomic considerations, and in relation to the utilization
    of atomic energy in the public interest."      See §§ 20.1(c);
    50.34a(a).    As the district court noted, if jurors make the ALARA
    determination, then this "results, essentially, in a negligence
    standard."    In re TMI Litig. Cases Consol. II, No. 88-1452, slip
    op. at 29 (M.D. Pa. Feb. 18, 1994).     Adopting ALARA as part of
    the standard of care would put juries in charge of deciding the
    permissible levels of radiation exposure and, more generally, the
    adequacy of safety procedures at nuclear plants -- issues that
    have explicitly been reserved to the federal government in
    general and the NRC specifically.      See Pacific Gas & 
    Elec., 461 U.S. at 212
    ("[T]he Federal Government maintains complete control
    of the safety and 'nuclear' aspects of energy generation. . .
    .").0
    Adoption of a standard as vague as ALARA would give no
    real guidance to operators and would allow juries to fix the
    standard case by case and plant by plant.     An operator acting in
    the utmost good faith and diligence could still find itself
    liable for failing to meet such an elusive and undeterminable
    standard.    Our holding protects the public and provides owners

    plants when it believes they have not complied with ALARA. Our
    holding does not diminish this NRC authority.

    and operators of nuclear power plants with a definitive standard
    by which their conduct will be measured.0
    V.   Exposure Relevant to Duty or Causation?
    The second certified question asks, "Whether a
    particular Plaintiff's level of exposure to radiation or
    radioactive effluents relates solely to causation or also to the
    duty owed by Defendants."   The district court held that, to prove
    a breach of duty, plaintiffs need not prove they were located in
    areas in which radiation exceeded permissible levels.     Instead,
    the court concluded that such evidence is relevant only to
    determine causation, i.e., whether plaintiffs' injuries were
    caused by the TMI accident.   See In re TMI Litig. Cases Consol.
    II, No. 88-1452, slip op. at 30-31 (M.D. Pa. Feb. 18, 1994).
    Defendants contend that plaintiffs must establish that
    they were located in areas exposed to radiation in excess of that
    allowed under §§ 20.105 and/or 20.106 to establish a breach of
    duty.   Like the district court, we disagree.
    A.   Regulatory Language
    0
    As one court noted, in adopting parallel regulations applicable
    to nuclear plant workers as the standard of care:
    In a highly technical field such as
    this, although a plaintiff should be provided
    a very high level [of] protection from
    excessive exposure to radiation, a defendant
    public utility should also be provided with
    some clear statement regarding how it may
    limit a worker's dose without exposing the
    worker to injury or itself to liability.
    O'Conner v. Commonwealth Edison Co., 
    748 F. Supp. 672
    , 678 (C.D.
    Ill. 1990), aff'd, 
    13 F.3d 1090
    , 1103-05 (7th Cir.), cert.

    114 S. Ct. 2711
    (1994).
    30
    The language of §§ 20.105 and 20.106, which regulate
    off-site radiation exposures, does not suggest that a breach
    occurs only when persons are exposed to excessive radiation.
    Instead, the regulations provide that a breach occurs whenever
    excessive radiation is released, whether or not anyone is present
    in the area exposed.   Because the relevant unit of measurement
    (the rem) defines radiation levels in terms of their effect on
    persons, 
    see supra
    note 14, the regulations must define
    impermissible radiation levels in the same way.   For example,
    §20.105(b) prohibits "[r]adiation levels which, if an individual
    were continuously present in the area, could result in his
    receiving a dose in excess of two millirems in any one hour," or
    "[r]adiation levels which, if an individual were continuously
    present in the area, could result in his receiving a dose in
    excess of 100 millirems in any seven consecutive days."   As the
    language suggests, this regulation does not prohibit only those
    emissions that actually expose individuals to certain radiation
    levels.   Instead, the regulation prohibits releases that could
    result in certain radiation levels if persons were present in the
    area.   We believe the regulation would not use the conditional,
    "if," if it was meant to specify that persons must be present in
    the area exposed.
    Similarly, the language of § 20.106 provides, "For
    purposes of this section the concentration limits in Appendix
    'B', Table II of this part shall apply at the boundary of the
    restricted area."   The regulation does not require that any
    person actually be present at the boundary line; it merely states
    31
    that the regulation is violated if the radiation at the boundary
    exceeds the Appendix B limits.0
    Therefore, the regulations provide that a violation
    occurs whenever radiation exceeds the §§ 20.105 and 20.106 levels
    -- whether or not persons actually are located in the exposed
    areas.   These regulations resemble those governing other areas of
    environmental safety, where the duty is breached by the release
    of pollutants, not by any subsequent personal injury.0
    0
    Section 20.106(d) mandates that "the concentration limits in
    Appendix 'B', Table II of this part shall apply at the boundary
    of the restricted area," except "[t]he concentration of
    radioactive material discharged through a stack, pipe or similar
    conduit may be determined with respect to the point where the
    material leaves the conduit." Therefore, to be precise, the
    regulation is violated when radiation exceeds the § 20.106 levels
    at the boundary of the facility or, if applicable, at a conduit
    exit.
    0
    For example, even absent allegations of personal injury, the EPA
    may impose penalties for, inter alia, violations of statutes and
    regulations governing air pollution, see United States v. B & W
    Investment Properties, 
    38 F.3d 362
    , 364 (7th Cir. 1994), cert.
    denied, 
    115 S. Ct. 1998
    (1995); and toxic substances, see Alm
    Corp. v. United States EPA, Region II, 
    974 F.2d 380
    , 381-82 (3d
    Cir. 1992), cert. denied, 
    113 S. Ct. 1412
    (1993). Similarly,
    "the NRC is authorized to impose civil penalties on licensees
    when federal standards have been violated." Silkwood v. Kerr-
    McGee Corp., 
    464 U.S. 238
    , 257 (1984) (citing 42 U.S.C. § 2282).
    These fines are available for violations of "any applicable rule,
    regulation or order related to nuclear safety," 42 U.S.C. § 2282
    (1988), not just those violations that result in personal injury.
    In fact, although defendants contend that no one was injured by
    the TMI accident, they received a $155,000 fine for violations of
    various NRC regulations and technical specifications. See Diane
    Sponseller, The Increasing Use of Fines as an Enforcement
    Mechanism, Pub. Util. Fortnightly, May 11, 1989, at 42, 42; see
    also Letter from Victor Stello, Jr., Director, NRC Office of
    Inspection and Enforcement, to R.C. Arnold, Sr. Vice President,
    Metropolitan Edison Company (Oct. 25, 1979). The penalty would
    have been higher -- regulators had wanted to fine defendants
    $725,000 for the violations -- but they were limited by a $25,000
    per month maximum on fines then imposed by the Atomic Energy Act.
    See 
    id. at 3.
    32
    B.   Tort Law
    Despite the regulations, defendants argue that, under
    traditional tort law principles, whether there has been a breach
    of duty is specific to each plaintiff.       Thus, defendants contend
    that the duty element requires a showing that each individual
    plaintiff was exposed to radiation exceeding the §§ 20.105 and/or
    20.106 permissible levels.
    Under Pennsylvania law0 and traditional tort
    principles, a negligence cause of action requires proof of four
    elements:
    1)   A duty or obligation recognized by the
    law, requiring the actor to conform to a
    certain standard of conduct for the
    protection of others against
    unreasonable risks;
    2)   A failure to conform to the standard
    required;
    3)   A causal connection between the conduct
    and the resulting injury; and
    4)   Actual loss or damage resulting to the
    interests of another.

    As we have noted, the 1988 Amendments retroactively required the
    applicable law for "public liability actions" be "the law of the
    State in which the nuclear incident involved occurs, unless such
    law is inconsistent" with federal law. 42 U.S.C. § 2014(hh)
    (1988). Although we have held that federal law preempts state
    tort law on the standard of care, 
    see supra
    part II, we find it
    useful to refer to state tort law in construing the relationship
    between the elements of duty and causation.
    33
    Prosser and Keeton on the Law of Torts § 30, at 164-65 (5th ed.
    1984).
    Whether a defendant owes a duty to a plaintiff is a
    question of law.   
    Kleinknecht, 989 F.2d at 1366
    ; see also
    Restatement (Second) of Torts § 328B (1965) (court determines
    whether "facts give rise to any legal duty on the part of the
    defendant" and "the standard of conduct required of the defendant
    by his legal duty").   Furthermore, the determination "whether to
    impose a duty is essentially one of policy."   Hoffman v. Sun Pipe
    Line Co., 
    575 A.2d 122
    , 125 (Pa. Super. Ct. 1990); see also
    Keeton et al., supra, § 53, at 358 ("[I]t should be recognized
    that 'duty' is not sacrosanct in itself, but is only an
    expression of the sum total of those considerations of policy
    which lead the law to say that the plaintiff is entitled to
    protection.").
    In this case, the applicable regulatory agencies
    already have weighed the competing policy considerations.     As we
    have noted, the Atomic Energy Commission viewed §§ 20.105 and
    20.106 as providing a balance between public safety and
    operational practicality.   See 25 Fed. Reg. 8595 (1960). Although
    the AEC noted that its regulations provided a "conservative
    standard of safety," it said it realized that "lower exposure
    limits would be used if considered practical" and "considerably
    higher exposure limits . . . would not have been considered to
    result in excessive hazards."   
    Id. Thus, the
    federal regulatory
    agencies have analyzed the competing policies in defining
    acceptable (and non-acceptable) conduct.   We hold that the duty
    34
    of care is measured by whether defendants released radiation in
    excess of the levels permitted by §§ 20.105 or 20.106, as
    measured at the boundary of the facility, not whether each
    plaintiff was exposed to those excessive radiation levels.
    Because defendants conceded that they violated §20.106,
    they violated their duty of care, thus satisfying the first and
    second elements of a negligence action.0   See 
    Griggs, 981 F.2d at 1434
    .   Of course, plaintiffs still must prove causation and
    damages before they may recover.     
    Id. This situation
    is analogous to the practice followed by
    many jurisdictions with negligence per se cases.   In such cases,
    where defendants violated the relevant statute or regulation,
    courts have held as a matter of law that plaintiffs have
    satisfied the first two elements of their cause of action: the
    duty and breach of duty.   Nevertheless, "[t]here will still
    remain open such questions as the causal relationship between the
    violation and the harm to the plaintiff . . . ."   Keeton et al.,
    supra, § 36, at 230; see also 1 J.D. Lee & Barry A. Lindahl,
    0
    We note that "the scope of the duty not to place others at risk
    is limited to those risks which are reasonably foreseeable."
    Maxwell v. Keas, 
    639 A.2d 1215
    , 1217 (Pa. Super. Ct. 1994); see
    also Keeton et al., § 43, at 280 (negligence "necessarily
    involves a foreseeable risk"). Thus, there may be cases in which
    plaintiffs were located far enough away from a defendant's power
    plant that any injuries from excessive radiation released at the
    boundary of the plant would be unforeseeable. See, e.g.,
    Palsgraf v. Long Island R.R. Co., 
    162 N.E. 99
    (N.Y. 1928).
    Nevertheless, we believe it is entirely foreseeable for nuclear
    power plant operators to expect that any excessive radiation
    releases might cause harm, even if the injured were not at the
    precise spots where the radiation exceeded federal levels, but
    instead were located in areas where radiation could spread via
    wind, rain, or water.

    ("Under the per se rule, the violation of an applicable statute
    is conclusive proof of negligence, leaving only the question of
    causation to be determined.") (footnote omitted).
    But defendants contend that, if individual radiation
    exposures are not considered in determining breach of duty, they
    will be forced to stand trial on potentially thousands of
    meritless claims.   We disagree.    As part of the causation
    inquiry, each plaintiff must demonstrate exposure to radiation
    released during the TMI accident.       See In Re Paoli Railroad Yard

    In Paoli, plaintiffs claimed they were injured by
    exposure to high levels of polychlorinated biphenyls, better
    known as PCBs.   We agreed with the district court that
    plaintiffs' prima facie case consisted of four elements:
    1) that defendants released PCBs into the
    environment; 2) that plaintiffs somehow
    ingested these PCBs into their bodies; 3)
    that plaintiffs have an injury; and 4) that
    PCBs are the cause of that injury.

    926 F.2d 262

    The first element represents a combination of the
    traditional duty and breach of duty elements, as stated in
    
    Griggs, supra
    ; it assumes that defendants had a duty not to
    release PCBs into the environment but did so anyway.      The
    remainder of the Paoli factors breaks up the causation and injury
    requirements into three elements, adding an "exposure" prong into
    the causation and injury inquiry.    As in Paoli, this analysis is
    useful here, where the substance that allegedly injured
    plaintiffs also occurs naturally in the environment.      This

    overturned the award. The court noted the plaintiff's evidence
    as to causation was insufficient because he failed to produce
    adequate evidence showing that he actually was exposed to dioxin
    and that dioxin caused his illness.

    Translated to this case, the Paoli factors require
    plaintiffs to show that: 1) defendants released radiation into
    the environment in excess of the §§ 20.105 or 20.106 levels; 2)
    plaintiffs were exposed to this radiation (although not
    necessarily at the levels prohibited by §§ 20.105 and 20.106); 3)
    plaintiffs have injuries; and 4) radiation was the cause of those
    injuries.   Although defendants concede the first element here,
    summary judgment still may be entered on any of the remaining
    issues, just as it ordinarily might be entered on the question of
    duty or breach thereof.   See, e.g., In re Agent Orange Prod.
    Liab. Litig., 
    611 F. Supp. 1290
    (E.D.N.Y. 1985) (granting summary
    judgment to defendants because, even accepting plaintiff's claim
    that he was exposed to Agent Orange, "there is no proof that the
    diseases and symptoms suffered by him were caused by Agent
    Orange"), aff'd on other grounds, 
    818 F.2d 210
    (2d Cir. 1987),
    cert. denied, 
    484 U.S. 1004
    (1988); Latimer v. SmithKline &
    French Labs., 
    919 F.2d 301
    , 304 (5th Cir. 1990) (affirming
    summary judgment on causation element for defendant in case
    alleging injury from pesticide "because the evidence in the
    record does not establish the requisite exposure").   Therefore,
    contrary to defendants' assertions, our holding on the scope of
    their duty will not require them to stand trial on meritless
    claims.
    38
    VI.   Conclusion
    In sum, defendants violated their standard of care if
    they released radiation exceeding the levels permitted under
    §§20.105 and 20.106 -- whether or not individual plaintiffs were
    harmed.   Once defendants exceeded the federal standards on
    radiation emission, they breached their duty.   Plaintiffs'
    exposures to radiation remain relevant, but only to prove
    causation and damages.
    For the foregoing reasons, we will affirm in part and
    reverse in part.
