In recent years (1974 to present), the medical services pro- vided by R. A. Conard and the Brookhaven Medical Team were expanded to include sick call and body burden measurements of the returning Bikini population. Body burden measurements were made in 1974 (CO 75) and in 1977 (CO 77). In August 1977, the responsibility for providing body burden measurements was transferred from the Medical Division to the Safety and Environmental Protection Division at Brookhaven National Laboratory. The 1978 and 1979 body burden measurements of the Bikini population were conducted by the latter organization.
