recommends that studies be conducted as follows: A test planting program on Enjebi to determine when exposure would be within acceptable criteria without the removal of soil. A program to determine radioactivity levels in coconut and other food crops produced on Lujor, Kirunu, Bokojuo, Bokombako, and Runit (after plutonium cleanup). As an alternate to the preceding program, soil removal on Enjebi, followed by a test planting series to determine whether exposure for Enjebi residents would be within acceptable criteria. _ The assembly of a team of experts to make and interpret field yadiation and activity measurements, advise on cleanup actions involving plutonium and other radionuclides, and provide necessary health physics support for protection of workers, decontamination of workers and equipment, and packaging and handling of collected contaminated materials. It is recommended that this program be conducted under the auspices of ERDA. A comprehensive underground water lens sampling and analysis program for a minimum period of ] year. Bacterial content, salinity, and radionuclide content would be measured every twelve months. However, the primary emphasis would be on the development of understanding those processes which are operating or can be made to operate to reduce the ecological half-life of 9 Sr and +3’Cs5 below the radioactive half-life on the northern islands. Case 3 reasonably insures a safe habitation plan for the proposed return of the islanders and provides a means of eventual improvement of the environment for the benefit of all of the Enewetak people. Further, the controlling criteria for radiation exposure developed by the AEC Task Group can be best met by this particular alternative. This is most likely to provide the lowest possible exposure in accordance with accepted guidelines.
