bucdens would not have increased when new dietary items like pandanus and breadfruit became available for daily consumption. Furthermore, while the population may have been near equilibrium with their April dietary uptake, individuals within the population may not have been. This was apparent in the adult male 1376, body burden data where two individuals show no decline in activity between the April 1978 and January 1979 whole body count. In one case, the individual was present on Bikini for only 5 months prior to the April 1978 count. This places the individual at approximately 60% of his equilibrium body burden value. In the second case, there seems to be no clear explanation for the lack of any reduction in the body burden, however 1. the individual may have lived away from Bikini prior to the April count; hence, equilibrium was not established at the time of counting, or 2. the individual changed his diet pattern between April and September. These deviations from the norm do not alter the conclusion that equilibri- um or near equilibrium may have been reached for the population as a whole for 13766, Indeed, they illustrate variations about a mean value. Data collected between January 1979 and August 1980 also indicate that certain individuals have been ingesting 1376, at a rate which axceeds that of the sample population. This could in large part be due to visits to 3ikini or other contaminated atolls between measurement dates. The individual dosimetric data presented here clearly illustrates that at least 19% of the Bikini residents would have received a dose equivalent in excess of 5 mSv (0.5 rem) due to the ingestion of 1376, had the April 1978 activ. . . . 137 . ity ingestion rate of Cs continued. . : : .
