10 CFR 71 Question

["Roy A. Parker" <70472.711@compuserve.com>]

Ruth,
 
The simple and direct answer to your question is that I do not know, but
...
 
The A1/A2  values in  10 CFR Part 71 are derived from 49 CFR 173.435 and
those in  turn are derived from IAEA Safety Series 6 Regulations for the
Safe Transport of Radioactive Material 1985 Edition (Amended 1990).
 
Maybe Rick Rawl at IAEA can tell us.

Subject: 10 CFR 71 Question
 
 
Dear RADSAFERs,
 
Does anyone out there in RADSAFE land have an idea of the philosophy
underlying the exclusion of various radionuclides from tables of A1
and A2 values of 10 CFR Part 71?  In some cases the A1/A2 value for a
parent radionuclide is appropriate, but not for all exclusions.  We at
Sandia Transportation Technology Department would appreciate any
thoughts you might have.
