~ 2 -. from BNL accompanying the team. Medical examinations have not been done, since they were not indicated in view of the low levels of radiation to which the people are exposed. However, when physicians from the BNL medical team are at Bikini they have, for humanitarian reasons, examined and treated many individuals at the request of the individuals or health aide. No health problem or sickness has been noted which could be related to radiation exposure. The results of bioassay procedures have been most. important in forming a basis for reassurance of the people living at Bikini regarding their radiological safety. In order to assess the radiological hazard the following bioassay procedures have been carried out: 1. Radiochemical analyses on urine samples: pooled samples). (individual 24 hour and These analyses require sophisticated chemical procedures and are performed by the ERDA Health and Safety Laboratory in New York City. Such radiochemical analyses have also been carried out on water and indigenous food products. Analyses were made for 700n, 13765 and Pu, On one occasion nasal swabs taken on Bikini workmen were taken to the U.S. to be analyzed for Pu. 2. Direct measurement of radiation in the people by gamma spectro~ graphic analysis: To perform this analysis tons of radiation~free lead bricks were shipped to the Marshalls and a shielded counting facility set up in one of our air-conditioned trailers and transported to Bikini on our vessel (LCU-Liktanur). The measurement of body radiation by such analysis is very sensitive and requires complex electronic equipment and scientific personnel from BNL who are experts in this technique. D0tb bo
