Carson, Ed., pp. 742-7, Health Physics Society, Chapter, Boulder, Colorado, 1976. m A comprehensive and continuing radiological safety program is required for the Bikini and Enewetak people who desire to reinhabit their home atolls. The program includes analyses of external radiation levels, soil and ground water contamination levels, and radioactivity in terrestrial and marine biota . which comprise the human food chain. From these data, both external and internal doses and dose commitments will be made. In addition, projections of future radiological conditions will be postulated in order to provide appropriate guidance on projected land use and living patterns. Earlier dose assessments will be revised and updated, and dosimetry models will be refined to reflect actual trends as determined from the monitoring program. : Project personnel will provide a resource of expertise for establishment or independent review of radiation protection prograns associated with cleanup and rehabilitation efforts in the northern Marshall Islands, and for related health physics interests of the Division of Operational Safety. ,—., .,.. Field operations will be closely coupled with those of Brookhaven Medical Survey in the Marshall Islands, and Radiological Safety Program personnel will be of direct assistance to the Medical Survey whole body counting activities. Ancillary environmental radiological assessments will be made at Rongelap and Utirik atolls on an alternate year basis. 15. Relationship to Other Proiects: a) Surveys will be made in close conjunction with the BNL Medical Survey Team-. Assistance will be given to their effort. The annual sumey would be conducted during their visits to the Islands. b) Continued collaboration with the University of Washington, Laboratory for Radiation Ecology (LIU3)is anticipated on Division of Operational Safety environmental programs in the Pacific basin. c) Extensive use will be made of prior survey data. Consultations will be held with other participating agencies in developing the bases for the survey requirements. 16. 1 . i, w’ , Technical Progress in FY 1976 and Transition Period: A major survey was conducted at Bikini and Eneu Islands in February 1975 in response to Department of the Interior’s request for guidance on the siting of the second increment of housing construction at Bikini. This survey revealed unacceptable radiation levels at most of the proposed sites, suggested alternate sites, and laid the groundwork for a larger multiagency survey in (See Continuation Sheet) -- .__.. ———. ...- .. ...
