Whole body counting of people living at Bikini, Rongelap and Utirik has been conducted to determine whether or not body burdens for 13766 are within the federal guidelines and to directly estimate whole body doses. 4. Objectives of On-going DOE Monitoring, Research and Dose Assessment Programs in the Marshall Islands. A. Terrestrial Program The broad goals of this program are to develop the necessary data base for radionuclide concentration, transport and cycling in the terrestrial environment of northern Marshall Island Atolls. These data are the input for radiological assessments of alternate living patterns which serve as part of the information base for evaluating resettlement options at Enewetak and Bikini Atoll. The specific objectives are to: * Determine the concentration of radionuclides in local food products and assess the relative importance of currently used food products and proposed food products to the estimated food chain doses. : Delineate the rates of uptake, redistribution and removal of radionuclides in the ecosystem, and develop or refine the concentration factors for the critical radionuclides; ° Develop further understanding of radionuclide cycling in the terrestrial foodchains and derive guidelines for agricultural practices that will minimize population exposure via terrestrial foods; 12
