1977. Current in vivo data indicate that the equilibrium body burdens for 137¢s will range from3 Cito 30 uCi in the Bikini population. This corresponds to a 30-year internal dose equivalent that falls in the range of 11 to 110 rem. Bioassay data obtained from Bikinians during 1978 indicate that bone marrow dose $0.s0c10° for 30 years of habitation would be between 0.4 and 1.0 rem from Sr-90y10 Reviewing the Bikini dose commitment in this light, one immediately realizes that the inhabitants would receive a total body dose equivalent exceeding the ICRP eriteria®, Thus, for Bikini Atoll, we concur with the UCRL recommendation? that more must be done to lower the total body and bone marrow radiation exposures so that the Marshallese can live within the population dose equivalent recommendations.
