Bikini Island and Bikini Lagoon were contaminated
by fallout from nuclear weapons tests conducted at the
atoll by the United States from 1946 to 1958. The second
test,
Baker,
of the Crossroads
series was an underwater
detonation in 1946 that sank several ships in the lagoon,
including the USS Saratoga and the Japanese battleship
Nagato. The ships received high-intensity gamma-ray and
neutron bombardment from the Baker test, which induced
radioactivity in the metal structures. Some of the tests
conducted after the Baker shot
(there were 21 tests
in
all) injected contaminated carbonate particles into the
air, some of which were deposited across the lagoon
surface. Most of this contaminated soil then settled
onto the ships’ decks and other structures and on the
lagoon bottom. These sunken ships provide an interesting
location for divers. Recreational diving and swimming in
and around the ships raises the question of the
potential radiological dose from the radionuclides
801.
KEYWORD (S)
present in or on the ships and in the lagoon sediments.
The purpose of this paper, therefore, is to present an
analysis of the potential radiological dose to persons
who would dive near the sunken ships and live on Bikini
Island for a short period of time.
