30-year cumulative dose (Eneu, .27 rem; Bikini, 3.5 rem) (6) is relatively further below the standard (5 rem) than the initial annual one. Although the above external dose estimates are quite adequate for planning, it is to be noted that specific beta-ray exposure measurements at ground level (0-10 cm above surface) have not been published for Bikini. The Committee is therefore recommending that such measurements be made to make the estimates complete. 3.2 Internal Dosage: Food Food consumption not clear what (Appendix D). the is the Bikinians primary determinant of dose, will eat when they resettle but Bikini it is Atoll The Lawrence Livermore Laboratory team has assumed that the dietary estimates made by a Micronesian Legal Services investigator in 1979 for the Enewetak Bikini. people, then living on Atoll, would apply to The estimate were made for conditions under which imported foods might or might not be available. For practical reasons the committee uses a "planning diet" which assumes that local that Ujelang imports are available 75 percent produce is always available and of the year. The local produce includes coconut, some pork and chicken, pandanus and breadfruit, and fish. Very important imports are rice, flour and sugar as well as canned meats and fish. Knowing the composition of the diet and the average radionuclide content of the various foods in it, the daily intake strontium-90 can be estimated in pCi/day per person. of the diet to remain constant, the 30-year dose calculated initial by multiplying the (e.g., of cesium-137 Assuming the nature in rem 1987) (whole-body) daily intake cesium-137 by the conversion factor .00045 rem/pCi (Appendix D). to bone marrow will be about 7 percent consumption. 9000023 - greater and owing to is of The dose strontium-90
