The oral intake associated with the maximum urinary output 38 pCi/d of plutonium-239, or 76 pCi/d of the three transuranics would be (plutonium-239,-240; americium-241). It would seem impossible to eat this much; the minimum quantity would be 5.6 kg of clams every day (Table 4.2 #2). The 30-year whole-body dose from 76 pCi/d would be 2.96 ren. On the other hand, the median excretion of about 1 x 10-4 pCi/d would require eating 1.2 pCi/d of all three transuranics. This would be about 3 times the currently estimated oral input used by Livermore, based on the community type B diet, and Presumably would be possible. The 30-year whole-body dose would be .045 rem. It is curious and may be of some significance that the median of such an extended distribution should be within a factor of three of the diet method's single estimate. Summary. In summarizing the Brookhaven results, two estimates have been made to cover the uncertainties surrounding the transuranic determinations, one based on the median, the other based on the range from ninimum to maxinun.

The estimate falls below the 5 rem guide for 30 years even when the maximum transuranic estimate is used - one which would appear to be dietetically impossible. 9000640 |
