e. The population of land crabs should be sharply reduced because of their high content of sr??, f£. If pandanus trees 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 cst? and gr?° at the end of the first year of residence on the Atoll and as appropriate thereafter. Baseline surveys prior to relocation would be desirable. Resurveys of environmental radiation levels on the Bikini Atoll and estimates or radionuclides in food should be made periodically. Special efforts should be made to ensure a balanced and adequately nutritious diet. A dietary supplement of powdered milk would materially reduce sr?? uptake by relieving the calcium deficiency usually associated with their diet. Respectfully submitted: Shields Warren John C.
