This example shows that important features of the radiological picture at Enewetak can be missed if dose estimates are averaged over the entire Atoll. Table 5-9, page 5-51 DEIS Case 1 WB= 0.3 Rem in one year Bone= 2 Rem in one year (mineral bone) . These were determined for an average individual in the Atoll. AEC Case 1 . . WB= 1.6 Rem in one year Bone marrow= 2 Rem in one year See data for an individual on Belle, Section B, Volume II, pages 34-35, ‘current condition, living pattern-F. The significance of a bone marrow dose as high as the bone dose is that,traditionally, the standard for bone marrow is one third that for bone. Table 5-10, page 5-53 Annual dose for an average individual for the entire Atoll should not be used. to develop ratios to indicate comparisions with AEC annual dose criteria. There are several problems with this approach. First, use of estimates for an average individual ignores the fact that children are thought to be more sensitive to radiation injury than adults. Maximum annual doses presented in the Task Group report for use in the DEIS were derived through consideration of doses to the fetus and newborn, as well as to adults. Treatment of this important consideration seems to be missing in the DEIS except in material provided in the Appendix. Second, there are no standards for doses to an average individual for a geographical area containing a wide range of dose rates. The nearest category of Federal recommendations are guides for a population group where annual average doses are to be determined giving due consideration to the most sensitive members. .By way of comparison, basic dose guides for such a group would be one-third of the guides for the individuai. AEC criteria for annual exposures apply only to exposures of individuals using the condition specified by the Federal Radiation Council, namely, that this may be used when there is a sufficient level of radiological monitoring that exposures, including those of the most sensitive individuals, will be known. AEC criteria for exposures at Enewetak do not apply to an average individual on the entire Atoll or to a population group within which there would be a wide range of doses that make up the average.
