After soil removal, all areas should be ” “Sesurveyed to ensure nopieces or hot spots of!jplutonium remain. . Plutonium contaminatedsoil on IRENE should be handled as on YVONNE. Pieces of Pu metal are not expected to be found. Test plantings of food crops may be conducted on each of the ™no crops'! islands as designated by the Enewetak people. As édible 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 CzOPS can be safely resumed. 10. Lens water sampling andanalysis should be conducted, samples fo be taken over a periodof at least 12 calendar months, Bacterial content, salinity, and radionuclide content should be , measured. Radioactivity information will contribute to an tinder standing of processesoperating - or which can be made to Operate - to reduce the ecological half-life of Oy and +3’c5 below the radioactive half- life on the northernislands, _especially 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. 12. Base-line surveys of body burdens and urine content of 1376. and Sr 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, every other year. - 13. Methods of disposal of plutonium contaminated soil and scrap will have to be decided. Pending a decision, it is recommended that cleanup should accomplish the recovery of plutonium contaminated soil and scrap with storage on YVONNE. If disposal is deferred for further study, such study should be initiated promptly.
