Transuranics. Based on Table 4.2 #1, the plutonium-239,-240
exposure is 0.293 pci/d, and the 30-year doses are: whole-body,
-Ol11 rem;
red marrow,
.017 rem;
bone surfaces,
doses will be 35% of the plutonium-239,-240 ones.
dosage is therefore .015 rem, whole-body.
..14 rem.

Water. In the case of catchment water (Noshkin et al 1981), the
radionuclide levels are no higher than 3% of the guides. In the case of
ground water, the same is true except for strontiua-90, whose level is
about 25% of the guide (8 pCi/liter).
(These levels have been scaled to
1990.)
Inhalation. It is the transuranics that are of consequence. The
original estimates of respired dust were very mu: too high (Shinn et al
1980) and they have been reduced to make them mor. -ealistic (Robison
1988). The matter is discussed in Note 10. Takin. “he daily intake to
be 0.006 pCi/d, the 30-year adult dose is .027 rem iole-body,
.041 to
the red marrow, and .005 rem to the bone surfaces.
Summary.
The individual doses have been multiplied by 1.33 to
scale them back from 1990 to 1978, the year in which DOE-1982's samples.
were collected. It should be recalled that the following estimates
depend directly on the assumed diet.
