calendar months. Bacterial content, salinity, and radionuclide content should be measured, but primary emphasis of the program should be placed on development of an understanding of processes which are operating — or which can be made to operate - to reduce the ecological half-life of are and 1376, below the radioactive half-life on the northe islands, especially JANET. ll. An air sampling program should be conducted during cleanup in support of cleanup operations and to add to the body of available information on radioactivity levels in air, Base-line surveys of body burdens and urine content of 1370, and 90s, should be made for the Enewetak people prior to return to Eneweta Atoll, after the first year of residence, and as appropriate there= after. Resurveys of the environmental radiation and radioactivity levels should be made starting in the first year ef return and repeated every other year. To be determined is the adequacy of the dict and the actual average daily dietary inteke of radioactivity for various age groups for comearison with estimated levels and how radioactivity levels in water, air, soil, plants, and animals are changing with time. (Included should be collection of additional information on the chemical form and size distribution of “~~ in the air.) Pu particl- Information from such surveys will provide a continuins c:: of the radiological status of the people and the environment an2z will assure that the exposure criteria is not being approached or exceeded, 13.
