A unpredicted shift in winds shortly after the detonation of a large
thermonuclear device during Operation Castle at Bikini Atoll, Pactific
Proving Grounds, on March 1, 1954, caused deposition of significaht amounts
of fall-out on four nearby inhabited Marshall Isands . A survey was made to
determine the exposure of the island inhabitants. Twenty-eight American
servicemen on Rongerik Atoll received about 70 r and 23 Japanese fishermen
aboard their fishing vessel, the Lucky Dragon received significant
exposure. Sixty-four away from the detonation,
received an estimated dose
of fall-out equivalent to 175 r whole-body r radiation and BETA -ray
lesions of the skin, and slight internal absorption or radioactive
material. Eighteen people on a nearby island received about 69 r. The
status of 82 Marshallese people is reviwewed four years after their
exposure. Extensive physical examinations were carried out during the first
3 months after exposure, an repeated at six months and yearly intervals
thereafter. A brief summary of findings from these suveys is included.
Three deaths have occurred in the errosed group, but none was due to
radiation exposure. No abnormalities were observed in the 18 babies born to
exposed parents. During the discussion of this paper, M. Tsuziki reported
on the status of the 25 Japanese fishermen exposed in the same accident.
Examination four weeks after exposure showed leukopenia and r function and
jaundice; after 3 months, hyp- or asperima. One case was lost as a result
of severel hepaitis. After 4 years, all the surviving fishermen report
feeling well and appear to be good health. (C.H.)

On May 16, 1945, the day following the Runit Island test, a collection of
marine organisms was made from the reef area north of the test site within
the general fall-out pattern. Collecting methods, preparation of material
for counting, counting methods,
organisms are given.

Half life of the activity was approximately 180 days
and was tentatively identified as Na/sup 24/ and Ca/sup 14/.
