Basis for DOT Contamination Limits

[Hans D Oldewage <HDOLDEW@SANDIA.GOV>]

Does anybody know the technical basis behind the external alpha and
beta surface contamination limits specified by DOT/NRC?  Also, the basis
for the factor of 10 increase allowed for exclusive use shipments?  

We are beginning a Federal Register search to see if this information is
available, but any assistance from this forum would also be appreciated. 

Because I work for a contractor to the U.S. Government,  I have no
budget to offer for your time.   I am just relying on your sense of
patriotism, and your trust that this is good cause.

Please respond to me directly, and to the list if you think the information
may be useful to others.
