! ] t II. III. b. no imported food c. no imported food plus water shortage Live on Eneu Island - all food grown on Ineu except not all coconut from lineu (plus imported food): a. 10 percent Bikini Island coconut and coconut milk b. 50 percent Bikini Island coconut and coconut milk. Live on Bikini Island - all food grown on Bikini plus fish from lagoon (plus imported food). The age group in the population receiving the highest annual dose should be used. Average values should be used for external radiation levels (by island) as well as for contamination levels of items of the diet. The diet used for previous Bikini estimates should be updated for these predictions where needed. The aerial radiological survey data from the Bikini portion of the Northern Marshalls survey should be used. If for Options I, II, and IIT above there are any significant differences in the dietary intake within the population that could cause a few individuals (as opposed to consideration of differences among age groups) to receive higher doses, these should be evaluated. Annual whole body and bone marrow doses (in the highest year) for such individuals would be predicted. Finally, the exposure history for those who have already lived on Bikini Island must not be overlooked. In calculating 30year exposures for all three options, this past exposure must be included. Since the standard applies to the average exposure of a population, it is suggested that an average value be developed for those who lived on Bikini Island. This value will be included in all 30-year dose estimates.
