RE: DAC Values and Chemical Toxicity

[Craig Reed <CReed@novoste.com>]

Radsafers:

There is an expanded explanation of chemical vs. radiological toxicity
for acute and chronic exposures for Solubilty Classes D, W, and Y as a
function of U-235 enrichment in section 2.5 of the DOE HP Manual of Good
Practices (EGG-2530, UC-41, DE88 013620) for those radsafers unfamiliar
with uranium enrichment and that want a reference.

Although the 10CFR20, Appendix B values are based on radiological
considerations,
footnote 3 of Appendix B adds that for uranium with less than 5%
enrichment, the
chemical toxicity may be the limiting factor.

The opinions expressed are strictly mine.
It's not about dose, it's about trust.
