,. under the the BNL Safety follow-up currently whole residing and body Environmental counting Protccti.on of on Ejit or }fajuro Kili Island (M1 79). former Bikini Division along Island residents with Islands, Majuro Atoll, and on Field Measurement of gamma-emitting radionuclide body burdens was accomplished with a trailer-mounted shadow--shield whole body counter. ,Dosc commitments were calculated from the measured body burdens for many persons residing at Bikini Island during the years 1969 throush 1978. In addition to retrospective dose equivalents, whole body counting and bioassy techniques provided the dose equivalent commitments were calculated. data base from which These calculations, to- gether with external radiation measurements, provided a complete assessment of dose to the Bikini population from chronic exposure to important fallout radionuclides in their home atoll environment. Results In the following tables, the dose equivalent during the residency imterval and dose equivalent couu.n;.tments to bone, bone.marrow and the total body are presented. The ulean for the dose equivalent and dose equivalen~ commitment was determined from individual data points which represent a wide distribution of residence intervals. The mean value corresponds to the mean residence interval (years) for the population described. Residence intervals were determined through verbal interro~ation of participants i.n the personnel monitoring program. 3
