Surveillance of Facilities and Sites Marshall Islands Radiological Safety Program GK-01-01-52-3-(a Project Title: 14, Scope: (continued) 3, Definition of the annual contributions to dose via the inhalation pathway at Bikini, Rongelap, and Utirik. Special emphasis will be placed on continuous air sampling for wind- mediated resuspension of radionuclides in local soils; and on special measurements to define aerosol contributions re- sulting from human activity. 4. Development of radiological dose predictive models which involve both human and environmental monitoring data. (b) Supplement to 200 Word Summary: The FY 1979 budget request contains a significant increase over the FY 1978 allocation. This increase reflects a realistic assessment of operating costs imposed by the in vivo counting, bioassay, and air monitoring activities begun in FY 1978. Additionally, field trip activities and analytical laboratory services have substantially exceeded original estimates for the basic radiological safety program, and these costs are expected to continue. Finally, there are a number of peripheral programs of mutual interest to BNL and OES which will be cost-effective if included oe, | with the basic efforts, manpower and budget permitting. order of importance: l. These include in Definition of local diet patterns at all atolls of interest, and continuous monitoring of diets for seasonal changes and longert, term trends which might impact on realistic dose predictions. dee 2. Incorporation of public information and education programs into the total BNL effort to minimize the adverse psychological and sociological impacts of local radiological conditions and of our efforts to understand them. 3. Retrospective assessment of the radiological picture in the northern Marshalls prior to the establishment of the BNL program in FY 1975, 4, Continued collaboration with UW/LRE on OES radiological programs. 15, Relationship to Other Projects: This program will be logistically coupled wherever possible to the BNL Medical Program in the Marshall Islands. Technical collaboration will continue on matters of mutual interest. The radiological safety program will also bear directly on a retrospective reassessment of thyroid and whole body doses to the BRAVO fallout victims at Rongelap and Utirik, a new program for which funding is expected in FY 1978. The program will also interact cooperatively with related efforts at the University of Washington (LRE) and at Lawrence Livermore Laboratory. (See Continuation Sheet) Gy-Wt9
