No adverse health effects associated with radiation exposure, including cancer of any type, were found during these examinations. In May 1979, the notification and medical examination program was expanded to include the DESERT ROCK Volunteer Observers (Officer Volunteers). The volunteers received exposures ranging from a few millirem to about 17 rem; however, they were closer to ground zero than any other participants at the time of detonation, and some could have received neutron exposures. There were 43 officer volunteers (Tab HH). Subsequent research has shown that this count includes one person who participated in three shots and was listed three times, thus our current officer volunteer list contains the names of 41 individuals. Formal notification is scheduled to begin on July 31, 1979. Outside of this formal program, however, we have established informal contact with 16 of the officer volunteers over the past year. Twelve of these contacts came through toll-free telephone lines; one was contacted for aid in research; one was identified through his reputation (a recently retired Army Lieutenant General); and two were located through medical records. to be deceased--one by kidney tumor in 1967 Two are known (survivors awarded VA compensation in 1968), and one by heart attack in 1978. Eight are known to be, or have indicated that they are, in good or fair health. Three have indicated that they have developed medical problems that are not. related to radiation. One has indicated he has cancer. The health status of two is unknown. In June 1979, after careful evaluation to ensure the pilot over-25-rem program was functioning well, the notification and medical examination program was expanded to include all participants with annual exposures in excess of 5 rem. This threshold was chosen because 5 rem is the current Federal guideline for most radiation workers and is the best Single standard to represent permissible exposure levels for most DoD personnel at the time of the tests. Notification will be based not only on film badge records, but also on dose calculations or dose estimates which show a possible over-5rem exposure. It is initially estimated that about 783 DoD personnel will be involved in this program (Tab I). Initial notifications are programmed to begin in early August 1979, and the notification process will continue as NTPR research identifies additional personnel with over-5-rem exposures.
