-ll- ' For example, if the Bikinians returned in 1979 to Eneu, if the diet consists of both local and imported foods as shown in Attachmenrc 1, and if they spend no time on and consume no food from Bikini Island, (Attachments 5-9, Curve 1) their predicted maximum annual whole body and bone marrow doses and their 30-year whole body doses (average for the population) would be within the federal guidance of 170 mrem/yr and 5000 mrem/30 yr. Under these same conditions, exposures of the highest individuals would be within the 500 mrem/yr federal guidance for whole body and bone marrow but would exceed the 250 mrem/yr Enewetak criterion. Without imported food (Attachments 5~9, Curve 4) both predicted average population and highest individual doses exceed the 170 and 500 mrem/yr federal guidance, while the 30-year estimate of 4700 mrem/30 yr just meets the 5000 mrem/30 yr federal guidance but exceeds the 4000 mrem/30 yr Enewetak criterion. Furthermore, it must be recognized that there is a significant degree of uncertainty in the dose estimates because of the need to predict lifestyles of peoples. For most situations it is estimated that these values may be realistic to within a factor of two; under unusual circumstances they may be within a factor of three.17 These, then, would be the approximate error bands associated with the curves in Attachments 5-9. ‘ A summary comparison of these curves with the federal guidance and with the Enewetak criteria is given in Attachment 10.
