Although the data indieates thar ane 1376, body purdous did not increase between April and September 1978, ti" ~ 1). 2.3 Thee the body burdens would not have increased when new dietary items like pandanus and breadfruit became available for daily consumption. Furthermore, while the population may have been at equilibrium with their April-September dietary uptake, individuals within the population may not have been in equilibrium. This is apparent in the adult male 1376, body burden data where two individuals showed 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. Several possible explana- tions include 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 Septem- ber. These deviations from the norm do not alter the conclusion that equilibrium or near equilibrium had been reached for the population as a whole for mean value. 137 Cs.
