No edible land plants were found on the complex. REEF STRUCTURES Several large structures, mostly reinforced concrete, constructed on the coral reef are found between Nam and Iroij and one is located near the sand bar, Bokbata, southwest of Nam. All of these structures were surveyed withthe following results: 1. Able (Bokbata) Reef Structure - one small door and several metal pieces on reef 200-300 uR/hr. 2. Remainder 5-40 uR/hr. Charlie (Nam), Dog (Iroij) Reef Structure #1 - several small metal plates on top of concrete foundation 100-500 uR/hr (these are awash at high tide}. Remainder 5-10 yR/hr. Structures #2 and #3 - all readings less than 10 yR/hr. These structures were judged to constitute no radiological hazard and Trust Territory representatives assessed the physical hazard as insufficient to justify the costly and time consuming effort which would be required to remove them. DOSE ASSESSMENT The traditional living pattern of the Bikinians centers around communal life on the island of Bikini where the permanent village and social and religious centers were located. other islands, primarily Eneu. Temporary settlements were located on In view of the Ad Hoc Committee's recommendation to limit initial resettlement to these two islands, it is assumed that the doses received from brief visits to other islands in the Atoll] will be small relative to that received from residence on Bikini. In addition the uniformly low exposure rates encountered on Eneu represented a potential exposure which is negligible even for continuous occupancy. For this reason, the treatment of dose considera- tions will be limited to the island of Bikini. EXTERNAL DOSE ASSESSMENT As indicated previously the island of Bikini was extensively monitored with portable gamma survey meters. Because the soil samples indicated 32
