-11- ingestion pathway evaluation for these islands. The various possible living patterns toward which we are directing our. assessment efforts are listed in Table 1. These living patterns cover a range of possible exposures which could be incurred by a sizeable portion of the returning Bikini population and are the composite of information obtained from the Bikini people, Trust Territory personnel and from experience at Enewetak Atoll. In addition to living patterns, another major factor in determining the potential dose to the returning population is the assumed diet. A considerable effort was made in the 1972 Enewetak Survey (6) to establish a likely diet for the returning Enewetak population. Based upon those efforts and discussions with the Bikini people, Trust Territory personnel and our observation of the few families presently living on Bikini Island, the diets listed in Table 2 should reflect a reasonable estimate of the potential diet of the returning population. Two diets are listed: One for 1975 and another for 1980. The difference in the diets reflects our estimates of the availability of certain food products. For example, on Bikini most of the coconut trees are presently not bearing fruit and for the most part coconut fruit availability will be limited throughout the next 5 years. By 1980, however, sufficient coconut will be available so there should be no limitations on dietary intake of coconut due to unavailability. Similarly, Pandanus and breadfruit are not fully matured on Bikini Island and since it will be a few years before these plants are very productive, only a few fruit are occasionally available. Once again by 1980 the availability of both iP 5009886
