C Protocol 1974 Continued Page Seven Personnel Monitoring: Whole-body counts: 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, Measure-~ ments will be made on the following estimated numbers of people: at Utirik 30, Rongelap 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 Urinalvses: 24-hr urines for radiochemical analysis will be collected as follows: in Utirik 12, Rongelap 15, Bikini 20. Pooled samples may also be obtained. for iodine excretion studies. Diet: 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 expected that the Bikini diet will contain any native foods.) Aliquots of these diets will alsc 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.) Soil: 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 Utirik will also be checked including some of the northerflislands of Rongelap,. It is anticipated that a member of the Health Physics Department at BNL and someone from the University of Washington School of Fisheries will be designated to assist in the radiological surveys. Starting Fiscal 1975 it is expected the environmental radiation surveys will be directed by Mr. Charles Meinhold of the Health Physics Department at BNL. One objective is closer coordination with the medical surveys. It is hoped that the U. Washington personnel who have contributed so much in the past will continue to participate.
