Between 1946 and 1958, the United States conducted 23
nuclear tests at the Bikini Atoll in the Marshall
Islands. The single largest detonation was the Bravo
test, which resulted in extensive radioactive
contamination of a number of islands and prevented the
timely resettlement of the native population.
Since
1958,
many studies have been conducted to assess clean up
options and the internal and external radiation doses
the Bikinians would likely receive, should they resettle
the islands. Although the external dose rates from
{beta}
and
{gamma}
radiation have been previously
determined by aerial and ground measurement techniques,
technical constraints limited the assessment of external
{beta} dose rates from the Cs-137 and Sr-90/Y-90
contamination on the islands. Now, because of the recent
development of very thin thermoluminescent dosimeters
(TLDs), these external {beta} dose rates can be
measured.

This report is intended as a resource document for the
eventual cleanup of Bikini Atoll and contains a summary
of the data for the concentrations
of
{sup 137}Cs,
{sup
90}Sr, {sup 239+240}Pu, and {sup 241}Am in vegetation
through 1987 and in soil through 1985 for 14 islands at
Bikini Atoll. The data for the main residence island,
Bikini, and the most important island, Enew are
extensive; these islands have been the subject of a
continuing research and monitoring program since 1974.
Data for radionuclide concentrations in ground water,
cistern water, fish and other marine species, and pigs
from Bikini and Eneu Islands are presented. Also
included are general summaries of our resuspension and
