a c. The objectives of the cleanup are two: (1) Recovery of the pieces of plutonium that have been ’ observed on or near the island surface. (2) Recovery of plutonium contaminated soil. ad. Recovery ofplutonium in soil at concentrations greater than 400 pCi/g ¢ s 40 Dy at any depth these levels are found. Also, recovery of contaminated soil sufficient to reduce surface levels to a value well below 40 pCi/g 239, 240py, After soil removal, all areas should be resurveyed to ensure ‘mo pieces or hot spots of plutonium. remain. eo me Plutonium contaminated soil on IRENE should be handled as on YVONNE. Pieces of Pu metal are 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 tirneg at which planting of subsisvence and commercial crops can be safely resumed. 10. Lens water sampling and analysis should be conducted, samples to be taken over a period of at least 12 calendar montns, Bacterial content, salinity, and radionuclide content should be measured, Radioactivity information will contribute to an understanding of processes operating-~- or which can be made to operate - to reduce the ecological half-life of 99Sr and 137Cs below the radicactive half-life on the northern islands, especially JANET. li. 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. 12. 137 Base-line surveys of body burdens and wrine content of Cs _ and 90S; should be made for the Enewetak people prior to return to Enewetak Atoll, and periodically thereafter. Resurveys of the environmental radiation and radioactivity should be made in the first year of return and repeated, for example, 139 +
