both available. Imports unavailable indicates a condition where there is an absence of imported foods. Local foods is an LLNL expression for the locally grown foods of the MLSC and BNL surveys. local food items. Under normal conditions, imported foods are preferred over When imports are unavailable, it is assumed that local food consumption increases and that the intake of imported foods would be much more limited. This condition is then projected over a lifetime. LIVING PATTERNS Doses have been estimated for the major islands at each atoll assuming a continuous residence on each island and all local food derived from that island. Some of the islands listed are only used part time for residence or for agricultural purposes, but we have estimated the dose assuming continuous occupation to indicate the dose relative to current residence islands. DOSE CALCULATIONS BODY AND ORGAN WEIGHTS Data from BNL have been summarized to determine the body weight of the Marshallese people. 27,28 The average body weights of adult males are listed in Table 13. The average, adult male body weight is 72 kg for Bikini, 71 kg for Enewetak, 61 kg for Rongelap, and 70kg for Utirik; these are very near the 70-kg value of reference man.?! As a result, we have used 70 kg as the average body weight in our dose calculations. The average body weight for 113 adult females in the Enewetak population is 61 kg; it is 67 kg for 30 Utirik females and 63 kg for 36 Rongelap females.-” DIET The dietary intake data from the BNL survey and the maximum dietary intake data determined for adult females from the MLSC survey are the values used in our dose calculations. When the daily food intake in grams per day (Tables 4 and I!) are multiplied by the radionuclide concentrations in the food products (Appendix A), we obtain the average daily intake of radionuclides for the various atolls and islands (Table 14). 32
