-3- The following areas will require further study: 1. A study is needed to answer questions regarding resettlement of Enjebi. How fast are the radioactivitylevels in the environment being reduced? What are the important contributors to this re- duction? Are there feasible remedial measures? What are the actual radioactivity contents for locally produced foods? Answers are needed within five years for Enewetak Atoll. The information also will be applicable to Bikini Atoll in verifying the long-term radiation dose predictions. Criteria have been provided to DNA for cleanup of plutonium. Additional guidanceis required on feasibility of reducing the quantity of material requiring disposal, e.g., can plutonium be removed from the contaminated soil, and what is the cost of such action? This information will have an impact on the method chosen for disposal of contaminated material and therefore on the cost of cleanup. Answers are needed so that DNA can effectively deal with plutonium cleanup and disposal during the cleanup of other debris, expected to require two to three years of field work. Otherwise, AEC may well inherit a long-term problem. 3. Not all islands at Bikini Atoll were returned free of restrictions and several important food items were not growing and could not be sampled. New foods never before grownin the Atoll have been planted. A long-term followup of the radiological status of the environment and people of Bikini Atoll is being done, It is essential to insure that doses to the people rernain within the standards. It is necessary to determine when restrictions may be removed for certain islands. Current environmental monitoring data will be needed to answer * questions and allay fears at both Bikini and Enewetak. This isa long-term effort with results needed today. There is a need for current data on external radiation levels on Bikini Island to bring information up to par with Enewetak Atoll, Also, questions are being asked about the current radiological status of other atolls that received signiticant fallout from the 1954 Bravo test. External radiation surveys using the aerial survey system and surveys of food items are neededfor Rongelap, Rongerik, Ailinginae, and Utirik Atolls. There is an increasing number of inquiries about the radiation levels in these A olla, and little or no current radiation data. ent of ERS Departmen. Office ~ pietoriant§ ue RE SHNVES. |
