LLL/EV-8 2-22 ~298~ federal guidelines (1). The apparent conflict between the restrictions indicated by this outcome and the strong desire of the people to resettle Bikini and Eneu Islands has created the need for more detailed and refined assessments addressing options at both atolls. It was also decided that prior to the end of the Trust Territory Agreement the U.S. should evaluate the radiological conditions of all “of the northern Marshall Islands Atolls downwind of the Pacific proving grounds. The field program was conducted from September through November 1978. Assessing the very large body of data produced will take the next two years. Reference l. e. W.L. Robison, W.A. Phillips, and C.S. Colster, Dose Assessment at Bikini Atoll, Lawrence Livermore Laboratory, Livermore, Calif., UCRL-51879.5 (1977). Approach A data bank of radionuclide concentrations developed from continuing research and survey programs will be maintained. These data will be used in conjunction with models for predicting doses to bone, lung, and whole body from l37cg, and other selected radionuclides. AS an example, 90cr, 24lan, the latest lung model from the 239424 Pu, International Commission on Radiological Protection is used to develop dose estimates to lung and bone via the inhalation pathway. Whole body 13les dose calculations are based on the two-component retention models developed by the ICRP for 137es body burdens. The most recent publications by Spiers, et al. (2) on 90sr distribution in bone are used to predict bone dosesfrom 2%sr, In addition, information on diet and land use associated with alternate living patterns will be developed for each atoll under consideration to complete the dose assessments.
