Purpose Weapons testing in the Marshall Islands has resulted in residual radiological contamination on some atolls. The objective of this program is to assess radiological doses at Bikini, Enewetak, and other northern Marshall Islands atolls for each exposure pathway for alternate living patterns. These assessments will provide a basis for decisions on resettlement options. d. Background From 1947 through 1958 the evacuated Enewetak and Bikini Atolls in the northern Marshall Islands served as the U.S. nuclear proving grounds. In 1969 a limited clean-up and an initial phase of housing construction was begun at Bikini Atoll with the subsequent return of some of the Bikini people to Bikini Island. In 1972, the Enewetak people requested that they be allowed to return to Enewetak Atoll; a major survey and assessment program was undertaken to evaluate the radiological consequences of such resettlement. The conclusions were that the northern half of Enewetak Atoll was not suitable for resettlement and that terrestrial food chains were potentially the most critical radiological dose pathway. In 1975 during evaluation of plans for a second phase of housing construction on Bikini Atoll, cr =... af it was decided that a more detailed survey of Bikini and Eneu Islands was needed. The results of this survey indicated that people residing on Bikini Atoll would receive doses exceeding the U.S.
