Page 4 offers much hope at the estimated current body burdens. However, if the revised projections indicate body burdens attaining nanocurie levels, then in-vivo counting of all residents would be desirable. The fourth question, regarding possible health risks, depends upon current and future body burdens of transuranics in Bikini residents. Data presented to the TTG suggests that the average burden is ~ 20 pCi 2392405), | but may be higher or lower by a factor of ten or more. Using risk factors in the BEIR and similar reports, estimates of the health risk associated with this level of plutonium can be calculated and would be very smal]. However, the TTG believes this would be premature. Such estimates would better wait until the body burdens of the Bikini residents can be ascertained with more confidence. Also, such estimates of possible health consequences must be done in context with other radiation exposure, such as from the beta-gamma radiation from fission products dispersed on Bikini. The TTG is aware that obtaining answers to the questions discussed above requires a considerable degree of cooperation from the Bikini people. Efforts to obtain this cooperation might result in psychological or sociological stresses far-exceeding the potential hazard from radiation. The TTG is in no position to evaluate this problem, but would feel that the overall welfare of the Bikini people should be placed above any concern for precise evaluation of minimal radiation risks.
