After soil removal, all areas should be resurveyed to ensure no pieces or hot spots of plutonium remain. 8. X Plutonium‘contaminated soil on Boken (Irene) shouldbehandled ag onRunit.(Yvonne). Pieces of Pu metal arg not expected to be found. 9. Test plantings of food crops may be conducted on each of the "no crops" islands as designated by the Enewetak people. As edible parts of these plants become available, concentrations of significant radionuclides should be measured and compared with the radiological survey predictions. These studies will indicate times at which planting of subsistence and commercial crops can be safely resumed. 0. Lenswater sampling and analysis should be conducted, samples to be taken over a period of at least 12 calendar months. Bacterial content, salinity, and radionuclide content should be measured. Radioactivity information will contribute to an understanding of processes operating - or whigh can be ymade to operate - to reduce the ecological half-life of Ose and 137s below the radioactive half-life on the northern islands, especially Enjebi (Janet). . ll. A comprehensive air sampling program should be conducted ‘over a period of 12 consecutive months under conditions closely approximating human habitation and expected soil disturbance to provide information on radioactivity levels in air. This program could be conducted coincident with and support cleanup. 137... 12 ._ Base-linesurveysof body burdens andurine content of Sr should be made for the Enewetak people prior to and j return to Enewetak Atoll, and periodically thereafter.
