~~ . 8. Plutoniumcontaminated soil on IRENE should be handled the same as on YVONNE and using the sama general criteria for removal except it is not expected that pieces of plutonium metal will be found. Since it {s recommended that replanting of food crops be limited to certain islands, test plantings of pandanus, breadfruit, coconut, and arrowroot should be made, as soon as growth can be assured, on each of the islands indicated for such crops by the Enewetak people. As edible parts of these plants become available, their concentrations | of 905, 13766 | 239,240, and any other significant radionuclides should be measured and compared with the radiological survey predictions. These studies will provide for a determination to be made of the earliest time at which planting of food and commercial crops can be made on islands other than those listed in 2b. and 2c. above. 10. An underground lens water sampling and analysis program should be ‘conducted in which samples are taken over a period of at least 12 calendar months. Bacterial content, salinity, and radionuclide content should be measured, but primary emphasis of the program should be placed on development of an understanding of processes which are operating ~- or which can be made to operate - to reduce the ecological . . half-life of 7050 and 13 "Cs below the radioactive half-life on the northern islands, especially JANET.
