Dr. Martin 8B. Biles 4. -2- Since the 20Sr concentration {n pandanus represents the largest single cantributor to the internal dose, the effectiveness of the protective measures referenced in No 3, above, should be evaluated by appreprfate resampling. Since certain foods aot presently growing on the atoll (e.g. squash) may be planted following the return of the Bikinfans, 1t 1s suggested that a test plot of such garden variety foods be established on Efkini Island during the agricultural development phase. The mature crops and softs fn which they are growina should be sampled periodically. It fs suggested that a small number (approximately 100) of coconut trees and a few pandanws be planted {fn the near future on Nam, Enidrik or other {stands which may be used as plantations. This will provide samples useful {n evaluating the feasfbility of the unrestricted use cf the atoll. One of the major uncerta{nties in the estimation of the potential internal dose is that assoctated with the actual composition of the dfet. To help ta remedy this deficiency it fis suggested that: &. A record be maintained of the kinds and amounts of food imported. b. The Trust Territory representatives attempt to arrive at better estimates of the datly diet than are currently avaflable. The recommendations of the Ad Hoc Committee for the detereination of body burdens and the assurance of a balanced and adequately nutritious dist should be followed. A celcfum supplement would be particularly {aportant. A minimum monitoring program to verify predictions of exposure rate reduction, to assess new items of foods and to evaluate the impact of clearing and covering the village area on the exposure rate should be established. This program would fnclude, but need not be limited to: a. Monitoring of external exposure rates on Sikinf, Eneman and Aan.
