Monitoringand Assessment Program The radiological monitoring and assessment program in the Marshall Islands consists of field operations, laboratory studies and analyses, exposure assessments, and advisory services. During FY 79 three trips are being conducted to carry out whole-body counting activities among the Rongelap, Utirik and Bikini peoples, and to begin acquisition of baseline information from Enewetak people planning to return to their atoll. The approximate numbers of people included in this activity are: e Rongel ap ~100 plus controls Utirik ~100 plus controls — Bikinians ~ 200 ptus controls Enewetak ~ 100 TOTAL ~ 500 It is expected that two or three trips a year will be continued, with four or five professional staff participating on each trip. If circumstances require (e.g,, including all resettled Enewetak people, other atoll peoples), additional effort may be required. Environmental monitoring is conducted on the atolls of Enewetak, Bikini, Rongelap and Utirik. Included are studies of radionuclide transport mechanisms and exposure pathways to man (e.g., foods and food chains) from both the terrestrial and the marine environments. components on the several atolls. Also included are studies of the dietary At present, these efforts require four trips per year to the Enewetak and Bikini atolls, and two trips per year to the Rongelap and Utirik atol}s. Depending upon the specific purpose of each trip, five to seven professional staff persons participate. These “trips result in 2000-3000 samples of various types being rcturned from eee _ Antn al analytical examination each year.
