They were moved to Kwajalein Atoll in March 1948 and eventually to Kili Island in fall 1948. A second testing site was made available in 1947 when the Fnewetak people were moved from Enewetak to Ujelang Atoll. From 1946 through 1958, 43 tests were conducted at Enewetak and 23 at Bikini Atoll. The atolls of the Northern Marshall Islands are shown in Fig. 1. Some of the Bikini people elected to return to Bikini Atoll in 1971 after a limited radiological survey had been conducted and a radiological dose analysis completed. Housing was built and coconut, breadfruit, and Pandanustrees were planted on Bikini Island (B6). Coconut trees were also planted on Eneu Island (B12, see Fig. 2). In 1972, the Enewetak people requested to return to their home atoll. It was decided that prior to any resettlement, a thorough radiological survey should be conducted and potential doses estimated for Taka Atoll eous Atoll SVG Frongerik Ato Ailingmnae Atoll 9 Ailuk Atoll @ CY e Fig. 1.
