an individual departed from B3ixini Atoll. The dose equivalent commitment as de termined from these calculations are listed in Table 41, Column 4. The total body dose equivalent commitment listed in Column 6, Table 41 is the sum of Columns 4 and 5. The total bone marrow dose equivalent commitment re- ported in Column 7 was obtained by summing the data in Columns 3, 4 and 5. Figures 1 through 3 illustrate the distribution of the dosimetric information obtained from Table 41. Figure 1 describes the distribution of residence interval, net external exposure, 905, bone marrow dose equivalent commitment, 13705 total body dose equivalent commitment, the total bone marrow and total whole body dose equivalent commitments for the Bikini population sampled in April 1978. Figure 2 presents this information for males only while Figure 3 presents the female dose distribution. Discussion of Results 905. body burdens do not appear to be significantly different for males, females and adolescents; however, the 13705 bedy burden as summarized in Table 13 indicates that male versus female adult body burden means are significantly different. There was also a small difference between the body burdens of the adult females and all children. These differences suggest chat dietary and liv- ing patterns change as an individual matures thus effecting the body burden. This problem was addressed for external exposure in an earlier report (GU 77) and an estimated living pattern was developed for children, adult females and adult males. This information indicates that the adult males spend 5% more of their time in an environment which is radiologically substantially higher in activity than do the adult females. If one assumes that 5% more of the dietary uptake of radioactive materials occurs due to the longer duration of time spent in the interior section of the island, then one would expect that the mean adult 14
