Additional samples of soil, food and ash will be analyzed for I-129. S$r~90 and Pu-239, 240 analysis of teeth samples, especialiy that from exposed individuals, will be done. Data derived from the "“3ixini Ash” studies will be factored into the rafinement of che dose astimartea. fee and Living pattern studies will be updated. Expected Progress in FY 1982. Factors such as solubility of iodine isotopes in fallout, che sossibdle son sribucion from neutron induced activity, the imoact af thvroid seekers other than iodine isotopes on dose, and caniizence lavels far values oF derived quantities sucn as airborne aceivity concentrations during fallous will be invescizated. Otee and living pattarn studies will be updated. Expected Progress in FY 1983. Diet and living sattern studies and dose reassessment will continue until sompleted far all areas of iacarest in the Marshalls. Ze Future Accomplishments. The techniques and expertise developed in the course of this study could be sed to raassess doses to sonulations in other areas subjectad to exposure fron Tallouc or aven those cesulsing from occupational situations in the past. Addi-~ tionally, this study wili provide a better astinmate of the crue value for thyraid nodule incidence cer unizs rad enabling technically sound risk faccors to Se associated with ioniziag radiation exposure. Re RelLationshioa to Ocher Protects. ie This study wlll hels astabiish external and intarnal dose estimates from the cime of the incidence 9 the oresenc, and will complemenc che aerial survey : extarnal tadiation naeasuraments, over sthesa islands, which has Seen complatad. Togecher they should orssenc a raiiadle sicture of doses received dy she repulations and also enabie isse astimatas =o be srotected inca the future. *~ =» This study wili Se in close confuncetion with the 3NL Marshall Islands Radislogical Safety Progran (ZA—~)2-31-02). Conciaued collacoration with sche vaiversity of Washingcon, Laboratory of Radiation Zcolegy, and the Battelle Pacific Jorehwest Laboratory will Se maintained in the area of sample analysis and data sncargracacion.
