In March 1946, the United States relocated the Bikini people to
Rongerik Atol] to conduct a nuclear testing program at Bikini Atoll.
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
