Followup Studies and Actions Bikini Resettlement l. Coconut crab population reduetion in Bikini Atoll a. Collection of crabs, recording of data on size, weight, radionuclide content, island of collection. db. Study on current crab diet, radiomuciide retention half-time. c. Disposal of crabs. Note: the intent is to achieve a signifi- ‘ cant reduction in manber of crabs available for mman consumption, not to remove the specie from the atoll. - Population diet study &. Identification of items of the diet, quantity consumed, radio~ nuclide content. Initial determinations to be made when natives first return. Re-sampling to occur periodically and particniarly when locally produced food crops such as coconut and peandanas become available. Analysis to include determination of tritium intake. b. Determination of potassium and calcium intake. Determination of population body burdens a. Yearly determinations of body content of biologically important radionuclides (identified in Gustafson's reports) as a function of age and sex. First measurements to be made at time of return of population (when first group of families return). b. From data in a. above, determination of retention half-times for these radionuclides. Poison fish study a. A determination of fish of the reef and in the lagoon that may and may not safely be eaten. This study should be campleted and results made available to the population prior to their return. Medical studtes a. Physical examinations. bd. Study of radionuclide content of blood and urine. Radiation surveys a
