-23. Determinations should be made of body burdens of cesium 137 and strontium 90 at the end of the first year of residence on the Atoll and as appro- priate thereafter. Baseline surveys prior to relocation would be desirable. Resurveys of en- vironmental 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. 4. Special efforts should be made to ensure a balanced and adequately nutritious diet. For example, a dietary supplement of powdered milk would mate- rially reduce strontium 90 uptake by relieving the calcium deficiency usually associated with their diet.
