diet and consumption patterns at each of the atolls. Current information is timited but indicates that dietary habits may be atoll specific and that application of dietary information developed at one atoll may not be appropriate for another atoll. The Ujelang Diet Survey developed at Ujelang Atoll] is the best information available on the dietary habits of the Enewetak people. However, it is not clear that this diet will accurately reflect the diet of the people who have (or will) returned to Enewetak. Similarly, the diet of the Bikini population should be evaluated if they return to Bikini Atoll; if return to Bikini Atoll will be delayed for some time then preliminary evaluation of the diet of the population at their current places of residence would be in order. The diets of the Rongelap and Utirik populations also need to be studied in more detail. The data will have to be obtained in two ways: (1) have people live at the atolls for extended periods of time (months) and observe, estimate and measure where possible the dietary intake of the people; and (2) use questionnaires to help develop the information required on diet preferences and habits. One atoll per year would be an appropriate goal. Thus it would take 4 years to complete the initial work at the 4 atolls and some follow-up work in subsequent years would undoubtedly be required. 5.) External Gamma Exposure Rate Measurements External gamma exposure rates at Bikini, Rongelap and Utirik were measured in late 1978 as part of the Northern Marshall? Island Survey (NMIS); exposure rates at Enewetak were measured during 1979 and 1980 as part of the clean-up project. 1981. The data from the NMIS are being summarized and will be published in The external exposure rates at Enewetak are currently in press. 33 These
