Scope: (a) 200 Word Summary: A comprehensive radiological safety program will be maintained for the inhabitants of atolls in the northern Marshall Islands contaminated as a result of the U.S. Pacific Testing programs. The following items and services will be provided: 1. Environmental and personnel monitoring to provide data for BNL dose assessments and determination of radiological trends. 2. Individual and population dosimetry based on actual measurements. These data will be used to modify dose commitment prediet-ivemodels so that they accurately reflect future trends. ... 3. Suggestions based on field experience to mitigate doses via the more critical pathways. 4. A flexible resource of radiological expertise to independently review radiation protection programs associated with rehabilitation efforts in the northen MarshalIs, and for related health physics interests of OES in the Pacific Basin. Program activities for the coming fiscal year will emphasize the followi,no. 0. 10 .— In vivo counting of Bikini and Enewetak residents. These efforts will define baseline body burdens of gamma-emitting nuclides for new residents at both atolls, and will periodically assess changes in body burdens over time which might result from various exposure pathways. 2. Urine bioassay to define radionuclide excretion patterns from individuals, and to estimate ‘OSr and transuranic nuclide burdens. (See Continuation Sheet) . ----- . . . . . )
