recommends that studies be conducted as follows: e ‘A test planting program on Enjebi to determine when exposure would be within acceptable criteria without the removal of soil. This program has beeninitiated. e Case 3. === <A program to determine radioactivity levels in coconut and other food crops produced on Lujor, Kirunu, Bokoluo, Bokombako, and Runit (after plutonium cleanup). e Asan alternate to the preceding program, soil removal on _ jebj, followed by a test planting series to determine whether osure for Enjebi residents would be within acceptable criteria. e The assecnbly of a team of experts to make and interpret field radiation and activity measurements, advise on cleanup actions involvi i and other radionuclides, and advise on ~ necessary health physics support for protection of workers, decontamination of workers and equipment, and handling of collected contaminated materials. e <Acomprehensive underground wate Lin a » . - * program for a minimum period of 1 year. Bacterial content, salinity, and radionuclide content would be measured every twelve months. 3 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 ana '3’Cs below the radioactive half-life on the northern islands. This program has been initiated. e Anairconducted which would obtain samples representative of those that might be f- expected from the activities of the returned population. PY BEST AVAILABLE CO THE BEST COMBINATION OF FEATURES IS FOUND I IN THIS CASE CLEANUP IS PRACTICALLY COMPLETE; THE PROBLEMS OF CON TAMINATE D PANDANUS AND BREADFRUIT ARE MINIMIZED; RESTRICTION ON POPULATION MOVEMENT IS MINIMAL, EXCEPT FOR THE REST RICTION OF NO RESIDENCES OR AGRICULTURE ON ENJEBI: THE 30-YEAR DOSES ARE LOW; THE MAXIMUM ANNUAL DOSES FALL WITHIN GUIDELINES; AND THE INCREASED RADIOLOGICAL RISK, AEC EXPRESSED AS HEALTH EFFECTS, IS NO MORE THAN EQUAL TO THE RISK FRO M BACKGROUND RADIATION. ae eee ee ee ee oe | Kh 3 ‘s |
