The United States nuclear weapons production workforce has been provided a compensation program which covers claims from workers for radiation-related cancer. The compensation decision is made through individual dose reconstruction followed by an estimate of the likelihood that a cancer was as least as likely as not due to the worker's occupational exposure. This program, which was established under the U.S. Energy Employees Occupational Illness Compensation Program Act of 2000 (EEOICPA), compensates workers for cancer incurred as a result of exposure to ionizing radiation at over 300 U.S. Department of Energy and contractor facilities. Under the EEOICPA, the U.S. National Institute for Occupational Safety and Health (NIOSH) has been designated as the agency responsible for reconstructing the radiation doses received by these workers. To date, NIOSH has received more that 25,000 cases that require individual dose reconstructions to specific organs or tissues that developed a cancer. Because the risk models used to compute causation are time dependent, all doses are reconstructed on an annual basis. The reconstructed doses include exposures from all possible pathways, including internal, external, environmental and medical exposures. To ensure that these cases are expeditiously processed in a fair and scientifically defensible manner, NIOSH has adopted a triage process that expedites processing and a reconstruction method that, to the extent possible, relies on standard consensus models. This paper provides a discussion of: 1) our experience with the application of standard ICRP models to these dose reconstructions; 2) a description of the techniques employed to efficiently process the large volume of cases we have received; 3) the progress made to date in the completion of dose reconstructions; and, 4) the current distribution of compensation rates by cancer type.
