- 16 Bikini, and any exposure which may occur at Enewetak, however slight, we can expect the incidence of these conditions to increase in direct proportion to the amount of the exposure. BEIR Report 58-60, 87-91. The Sources of Ionizing Radiation The sources of ionizing radiation with which we are concerned here are of two kinds. First, the relatively brief, high exposure of the people as a result of the fallout from Bravo. Second, the long-term, low-level exposure at all of the islands from terrestrial sources of radiation and, of greater significance, the internal exposure of residual radiation via the food web. For those who received relatively high exposures, there is nothing to be done but observe and treat any ill effects that may have resulted from the initial exposure. Future potential doses through the diet, however, are subject to modification, if enough is known about the environmental sources of the radiation and the movement of the radionuclides through the food web. Summary of Needs It seems to us that, in varying degrees, the people of Enewetak, Bikini, Rongelap and Utirik have the same needs. - They are four-fold: ve gs hye “os - wu
