OPINION
This appeal is a companion to In re Hanford Nuclear Reservation Litigation, 292 F.3d 1124, also decided today, and also involves the claims of multiple plaintiffs exposed to radiation from the Hanford Nuclear Reservation in southeastern Washington between 1943 and 1987. The facts underlying these claims are set forth in detail in our opinion in In re Hanford Nuclear Reservation Litigation. The plaintiffs in this case, originally part of the group of plaintiffs in Hanford, were severed from Hanford during the second phase of discovery on September 20, 1996, for reasons we need not detail here. The record in this appeal includes an expert’s report that is not in the Hanford record. The same district judge who handled Han-ford also granted partial summary judgment in favor of the defendants in this case, and also on the erroneous premise that only those plaintiffs who were shown to have been exposed to radiation that exceeded what is termed a “doubling dose” could recover. We therefore, as in Han-ford, reverse the grant of partial summary judgment. We also deal with claims for emotional distress and medical monitoring not litigated in Hanford.
I. “Doubling Dose”
A “doubling dose” is a level of radiation that doubles the risk of the disease or injury in question when compared with the risk experienced by the general population as a whole. As we explained in Hanford, reliance on that standard was error because the “doubling of the risk” is a measure courts use to determine whether a substance is capable of causing harm in the absence of any evidence other than epidemiological evidence of toxicity. Hanford at 1134-37. Here, we deal with a substance, radiation, that is known to be capable of causing harm. See Hanford at 1136-37. Indeed, there is no threshold harmful dosage level for radiation because it can cause harm at any level. In re Three Mile Island Litig.,
What differentiates these plaintiffs’ causation cases from Hanford is the evidence relied upon by the plaintiffs. Plaintiffs in this case submitted a report prepared by Dr. F. Owen Hoffman, Ph.D. Dr. Hoffman’s report established a generic methodology that was intended to be used to estimate doses and risks to specific individuals. Dr. Hoffman, using “representative” plaintiffs, also provided ranges of the estimated probability that certain diseases were caused by the radiation exposure, depending upon gender, year of birth, age at first exposure, time since first exposure, and whether the exposure was acute or chronic.
The district court held that the only plaintiffs who could proceed were those whose median, or central value probability of causation (“PC”) estimates, exceeded 50%, reasoning that this threshold equated to a showing of more than “doubling the risk” of disease. The 50% level corresponds to a probability that an individual has a disease caused by radiation that is twice the probability of such disease in the population as a whole. For example, according to Dr. Hoffman’s estimates, a woman born in 1945 and living in Richland, Washington, who ingested milk from a backyard cow and was diagnosed with thyroid cancer in 1955, has a range of PC estimates from 59% to 99%. The median
The district court’s adoption of a “doubling of the risk” standard was error. We explained in Hanford that generic causation is only part of the causation inquiry. Hanford at 1133. In order to establish causation, a plaintiff must show that the radiation was both capable of causing his or her disease and that it in fact caused his or her disease. See Bonner v. ISP Technologies, Inc.,
Nor is epidemiological evidence the sole method of establishing causation. See Glastetter v. Novartis Pharm. Carp.,
II. Emotional Distress Claims
The district court held that plaintiffs’ claims for emotional distress and medical monitoring are cognizable under the Price-Anderson Act even if plaintiffs had not suffered any known physical injury. Although the defendants did not file a cross-appeal, our consideration of this issue is nevertheless appropriate. Parties may raise challenges to subject matter jurisdiction at any time. May Dept. Store v. Graphic Process Co.,
First, the statutory language of the Price-Anderson Act provides jurisdiction in federal courts for an “action arising out of or resulting from a nuclear incident.” 42 U.S.C. § 2210(n)(2). A “nuclear incident” is defined in the Act as “any occurrence, including an extraordinary nuclear occurrence, within the United States causing, ... bodily injury, sickness, disease, or death, or loss of or damage to property, or loss of use of property.” 42 U.S.C. § 2014(q). Physical harm to persons or property is thus a jurisdictional prerequisite.
[5] The Act also provides that “the substantive rules for decision in such action shall be derived from the law of the State in which the nuclear incident involved occurs, unless such law is inconsistent with the provisions of such section.” 42 U.S.C. § 2014(hh). Thus, although Washington law permits emotional distress claims in the absence of physical injury, see Whaley v. State,
In fact, Washington law respects binding restrictions on claims for emotional distress. The Washington Supreme Court interpreted a provision of an insurance contract with identical language to that contained in the Act and concluded that “bodily injury” precludes recovery for “purely emotional injuries.” Daley v. Allstate Ins. Co.,
We turn from the statutory language to the legislative history of the Price-Anderson Act. The legislative history indicates that Congress added the words “sickness” and “disease” after “bodily injury” in order to clarify what it meant by “bodily injury.” Congress intended to make clear “that the extent of bodily injury was the same as the definition of bodily injury as specified by the standard NE-LIA insurance policy.” S.Rep. No. 296, 85th Cong. 1st sess. 1817-18. NELIA is the Nuclear Energy Liability Insurance Association, an association that provided a specialized form of nuclear energy liability insurance. 10 C.F.R. § 140.91, Appendix A. NELIA policies insured against bodily injury or property damage caused by nuclear incidents. Id. Since NELIA policies did not provide coverage for purely emotional injuries, we conclude that Congress intended the same scope for the Act.
Finally, we take guidance from the jurisprudence interpreting a similar provision in the Warsaw Convention. The Convention is an international treaty that governs liability concerning “all international transportation of persons, baggage, or goods.” Carey v. United Airlines,
Article 17 of the Convention provides that an airline is “liable for damage sustained in the event of the death or wounding of a passenger or any other bodily injury suffered by the passenger” if caused while on the aircraft or while “embarking or disembarking.” Carey,
Our decision is in harmony with other federal court decisions. See Dodge v. Cotter Corp.,
III. Medical Monitoring Claims
The district court also determined that it had jurisdiction to consider claims to recover costs of medical monitoring for plaintiffs who do not yet have a detectable illness but who were exposed to radiation dosages that exceeded federal dose limits. The district court correctly observed that the Washington Supreme Court had not yet recognized such a cause of action for medical monitoring. Defendants argue on appeal that claims for medical monitoring, like emotional distress claims, are not included within the Price Anderson Act’s jurisdictional provisions, absent “bodily injury, sickness, disease, or death ... or property damage.” 42 U.S.C. § 2014(q). They ask this Court to affirm the district
We agree with defendants that a cause of action for medical monitoring because of a future risk of disease, and absent a present physical injury, also fails to meet the jurisdictional requirements of the Price Anderson Act. We see no defensible distinction between emotional distress claims for plaintiffs who do not demonstrate “bodily injury, sickness, disease, or death ... or property damage,” and medical monitoring causes of action brought by such plaintiffs.
The court in Duncan v. Northwest Airlines, Inc.,
Our conclusion is consistent with our decision in Durfey v. E.I. DuPont De Nemours & Co.,
IY. Conclusion
We affirm the district court’s dismissal of medical monitoring claims because they are not cognizable under the Priee-Anderson Act. We affirm for the same reason the district court’s dismissal of some of the emotional distress claims and remand for dismissal of the remaining emotional distress claims, i.e., those of plaintiffs who claim no physical injury. We reverse the district court’s partial summary judgment in favor of the defendants on causation issues. We recommend that the district court on remand reconsolidate these plaintiffs’ claims with the claims of plaintiffs in the accompanying Hanford appeal.
AFFIRMED in part, REVERSED in part, and REMANDED. Costs are awarded to the Plaintiffs-Appellants.
