BROOKHAVEN NATIONAL LABORATORY ASSOCIATED UNIVERSITIES, INC.. UPTON, L.I.. N.Y. 11973 MEDICAL DEPARTMENT TELEPHONE: (516) 345-3577 Division of Biomedical & Environment a1 Rese arch With regard to the plutonium problem on Bikini we would like to bring you up to date on (1) sample collections planned for Sept.-Oct. survey in the Marshall s ; (2) samples still being analyzed from previous surveys, and ( 3 ) summary Tables of previous d a t a comparing Rongelap and Uti rik findings. Samples for Sept.-Oct. 1976: Urines 1. Bikini : 5gal. carboys on 5gal. pooled samples; 6. Majuro: 5 - 5gal. pooled samples and samples on 50 Bikini people planning to return in the near future. You will note we are collecting samples from a number of atolls not directly envolved inthe 1954 fallout. Whole body gamma spectroscopy on Bikini people (for 137Cs body burdens) originally planned for October are being delayed until April i n hope that the advance group of Eniwetak people will have returned to their atoll and can also be counted during that operation. N. Greenhouse, J. Naidu and V. Nelson plan on collecting soil and plant samples i n Sept.-Oct. from Wotje, Ailuk, Uti rik, Rongelap and Samples presently being analyzed are animal samples (pig, chickens, crabs from Rongelap and Bikini, water from Bikini cisterns,soil from Rongelap. Autoradiographs for alpha tracks of animal lung and liver tissues are being run.

The enclosed Tables have been compiled by N. Greenhouse, J. Naidu and me and include data from various sources. Many of the Tables are incomplete. We are attempting to pull together in one file all available data from personnel and environmental radiological surveys on Rongelap, Uti rik and Bikini atolls. When this is accomplished we should be able to make more comprehen sive comparative Tables on these atolls.We hope these data will be on hand for your planned meeting of the experts,
