During the rehabilitation and repopulation years, the medical services provided by R.A. Conard and the Brookhaven Medical Team at Rongelap and Utirik were expanded to include sick call and body burden measurements at Bikini. Body burden measurements were made in 1974 (Co75) and in 1977 (Co77). In August 1977, the responsibility for providing body burden measurements was transferred from the Medical Department to the Safety and Environmental Protection Division of BNL. The 1978 and 1979 body burden measurements of the Bikini population were conducted by the latterorganization. In August 1978, the Bikini people were relocated, to Kili Island and Majuro Atoll following increasing body burdens of 13 Ss. Removal of the Bikini population from Bikini Atoll eliminated the Cs source term from the diet and limited the dose equivalent received by this population. The scheduling of the first Enewetak nuclear test necessitated the removal of the people in 1947, On December 3, 1947 the Governor of the Marshalls flew to Enewetak and proposed to the chiefs that they move to Ujelang Atoll, which was then being prepared as a relocation site for the Bikini people. The two chiefs, Johannes and Abraham, were flown to Ujelang on December 4th and later returned to Enewetak after selecting sites for dwellings and comminity buildings. Temporary living quarters were ready for the people of Enewetak when they went to Ujeland on December 21, 1947. Permanent facilities on Ujelang were constructed in the spring of 1948, On May 28, 1948 resettlement was completed. The first three nuclear test, the Sandstone series, were completed by May 14, 1948 and no additional tests were conducted at Enewetak until 1951. The last test was completed in July 1958. In September 1974, the people of Enewetak and their advisors returned to Enewetak for a meeting with representatives from the Defense Nucler Agency, the Department of the Interior, and the Atomic Energy Commission. The purpose of the meeting was to present the draft environmental statement regarding the proposed project to rehabilitate the atoll, and to return the former residents there. In February 1980, members of the BNL Marshall Islands Radiolocial Safety Program conducted a field trip to Japtan and Enewetak Islands, Enewetak Atoll and Ujelang Island, Ujelang Atoll. The purpose of this trip was to obtain baseline radionuclide body burden data on the Enewetak population prior to the repatriation in April 1980. The people of Enewetak repatriated the islands on the southern part of the atoll. Certain northern locations of the atoll have been off limits except for short visits. Most of the food is imported at this time. Monitoring of inhabitants has occurred on an annual basis since the people's return. 39
