10 CFR 835 and EPA 400-R-92-001

[Michael McNaughton <mcnaught@lanl.gov>]

Dear RadSafers

Can anyone explain why the dose conversion factors and dose response levels
in EPA 400-R-92-001 (Manual of Protective Action Guides) are not consistent
with the derived air concentrations in Appendix A of 10 CFR 835. The values
for uranium are consistent but the values for transuranics differ by about
a factor of 3.

Thank you, mike
