(which is very low) and from radionuclides remaining in the soil from nuclear tests at Bikini Atoll; 2) internal irradiation from radionuclides deposited in the body as a consequence of eating foods from the island area (including foods grown in the contaminated soil and marine life from the lagoon) and from inhaling airborne radionuclides. Because of metabolic characteristics of the predominant radionuclides and strontium-90) at Eneu, bone marrow doses the (cesium-137 are expected to be slightly greater than whole body doses, and will be the limiting exposure. The external radiation dose rate has been determined from data obtained during a recent aerial radiological survey. The external doses to whole body and bone marrow for Eneu residents were calculated using measurements of external radiation and estimates of time spent in various areas of the island (e.g., village, island interior, on the lagoon, etc.). The internal radiation doses were calculated from estimates of the amounts and kinds of food in the diet (with and without imported foods) and from measurements of drinking water the radionuclide content of these foods (see Attachments 1, 2, 3, and 4). and of Levels of radio~ activity in food shown in these attachments were obtained from analysis of samples collected on Eneu Island, except for pandanus which was not yet available. Since pandanus would be a diet constituent, the contributed dose is calculated from uptake coefficients and soil concentrations of radionuclides. The 30-year dose commitment is calculated assuming only radioactive decay with no reduction from other possible mechanisms.
