APPENDIX A CHRONOLOGY OF SELECTED EVENTS RELEVANT TO THE NTPR PROGRAM Early 1977 Centers for Disease Control (CDC) identified a former participant in U.S. atmospheric nuclear weapons testing who had leukemia. CDC suspected an abnormal incidence of leukemia among participants in Shot SMOKY, conducted on 31 August 1957 as part of Operation PLUMBBOB. 6 May 1977 Ad hoc Department of Defense (DOD) committee met to formuTate goals and an agenda for conducting a detailed review of troop participation in the atmospheric nuclear test program. The committee was chaired by the Director of the Defense Nuclear Agency’s (DNA’s) Armed Forces Radiobiology Research Institute (AFRRI) and included representatives from various Army organizations, such as the Office of the Surgeon General, Office of the Deputy Chief of Staff for Operations and Plans, and Office of the Chief of Public Affairs. 3 June 1977 DOD, Department of Energy (DOE), Reynolds Electrical & Engineering Company (REECo), and Los Alamos National # Laboratory (LANL) representatives met at the DOE Nevada Operations Office (NVOO) in Las Vegas to determine the availability of information on personnel exposures to ionizing radiation during the atmospheric nuclear tests. 15 June 1977 AFRRI provided initial participant information to CDC concerning the Provisional Company, 82nd Airborne Division, which was one of the Army contingents that had been at Shot SMOKY. 3 November 1977 Interagency committee, involving DOD, DOE, the Veterans Administration (VA), and the U.S. Public Health Service, met to discuss the possible long-term health effects resulting from participation in atmospheric nuclear weapons testing. The attendees recommended that a major epidemiological study of test participants be undertaken under the direction of an independent scientific organization and that a central administrative unit be established within DOD to coordinate all related activities. 1 December 1977 Meeting convened by the Assistant Secretary of Health for Health Affairs to address the atmospheric nuclear weapons testing program and the possible relationship between participation in the program and an increased incidence of disease attributable to radiation exposure. Participants included representatives from the military services, Defense Nuclear Agency (DNA), DOE, VA, CDC, and National Research Council (NRC) of the National Academy of Sciences (NAS), as well as epidemiological consultants from Walter 197
