3 > CONCLUSIONS AND RECOMMENDATIONS RESULTING FROM 1967 RADIOLOGICAL SURVEY OF BIKINI ATOLL The exposures to radiation that would result from che repatriation of the Bikini people do not offer a significant threat to their health and safety. Such exposure may and should be further reduced by the following simple measures: a. Restrict rehabilitation for the present to the islands of the Bikini-Eneu complex. b. Establish the first village and immediate food crops on Eneu. No radiological precautions will be needed on Eneu because of its very low contamination level. ce. Any village construction on Bikini Island should involve the covering of the site with coral rock as is the local custom. d. Radioactive scrap metal should be removed from the islands e. The population of land crabs should be sharply reduced because £. adjacent to former shot sites. of their high content of Osr, If pandanus trees which produce edible fruit are planted on Bikini Island, two inches of topsoil should be removed from the planting sites. The area of removal from each site should be equal to the area covered by the crown of mature trees. Determinations should be made of body burdens of 1375 and sx at the end of the first year of residence on the Atoll and as appropriate thereafter. Resurveys of environmental radiation levels on the Bikini Atoll and estimates of radionuclides in food should be made periodically. These surveys will provide a* continual check of the radiation status of the people and environment and will help form a basis for decision as to the time of rehabitation of islands outside of the Bikini-Eneu complex. Special efforts should be made to ensure a balanced and adequately nutritious diet. For example, a dietary supplement of powdered milk would materially reduce 90sr uptake by relieving the calcium deficiency usually associated with their diet. -~ 10 = Attachment 5
