RE: 15 or 25 mrem per year?
ER then things have changed a bunch. I attended a local chapter meeting on
a clean up project [I think it was part of the Rocky Flats clean up but
maybe not.] Anyway the contractor assumed that if they documented meeting
the EPA's 15 mrem that would be acceptable to the NRC. I hope nobody is
surprised that they were wrong and had to do a whole separate report
documenting that they had met the 25 mrem figure for the NRC.
Of course things change and this was say 3 to 5 years ago.

Considering all the uncertainties in the calculations, it should not make a
bit of difference. Of course the folks at the EPA would then insist that
conservative is better.
Actually, I think on at least one occasion EPA has agreed to 25 mrem. On
October 10, 2002, NRC News No 02-120 was released in which the NRC announced
that that the NRC and EPA had reached an agreement in which the EPA agreed
to defer exercise of authority under CERCLA Act for the majority of NRC
facilities to be decomissioned. This I have taken to mean that they are not
going to argue with the NRC. The copy of the MOU I have doesn't get
specific on doses, so presumably the NRC number is the controlling one.
However, there is a table of permissible contamination levels for
radionuclides in soil. How the numbers were devied is not stated.
