Protocol 1974 Continued Personnel Monitoring: Whole-body counts: Page Seven Dr. Stanton Cohn and Mr. John Rothmann will carry out whole-body gamma spectrographic analyses on personnel using a shadow shielded detector in an air-conditioned trailer aboard the LCU which will be beached. A shower facility will be available and the subjects to be counted will be clothed in paper pajamas. Mcasurcments will be made on the following cstimatcd numbers of people: at Ucirik 30, Rongclap 80 and Bikini 40 workmen and a sample of Bikini people if they have returned. 40K samples will be used to evaluate lean body mass for the diabetic survey. Radiochemical Urinalyses: 24-hr urines for radiochemical analysis will be collected as follows: samples may also be obtained. for iodine excretion studies. Diet: in Utirik 12, Rongelap 15, Bikini 20. pooled Aliquots of these samples may also be used A number of typical Marshallese diets will be obtained at Rongelap and Utirik for radiochemical analyses. (It is not expectec that the Bikini diet will contain any native foods.) Aliquots of these diets will also be tested for iodine and CHO etc. for the diabetic study, Cocoanut crabs will be collected from various parts of Rongelap, Utirik and Bikini atolls for analysis, Drinking Water: analyses. Samples will be collected at Bikini for radiochemical Fruits: Cocoanuts, pandanus, arrowroot and other plants will be collected for radiochemical analyses at Utirik, Rongelap and Bikini. (Bikini samples will also be tested for Pu and Am.) Soii: Samples will be tested for radionuclides at all three atolls and at Bikini also for Pu and Am. Gamma Radiation Levels: A survey of Bikini Island for radiation levels will be an important part of the survey there. Levels at Rongelap and Ucirik will also be checked including some of the northerislands of Ronyelap. It is anticipated that a member of the Health Physics Department at BNL and someone from the University of Washington School of Fisherics will be designated to assist in the radiological surveys. Searting Fisca! 1975 it is expected the environmental radiation surveys will be directed by Mr. Gharles Meinhold of the Wealth Physics Department ac BNL. Onc objective is closer coordination with the medical surveys. It is hoped that the U, Washington personnel who have contributed so much in the pase will continue to participate.
