Curtis:

Montana is a non-agreement state.  U.S. NRC regulations apply in this 
case.

§ 40.13 Unimportant quantities of source material
http://www.nrc.gov/reading-rm/doc-collections/cfr/part040/part040-0013.html

Note specifically 10CFR40.13(a) to see it applies to your situation.  You 
will need to evaluate the mass of thorium per mass of compound or mixture 
for the specific Thorium Oxalate for which you are determining whether or 
not an exemption applies.

10CFR40.22 Small quantities of source material
http://www.nrc.gov/reading-rm/doc-collections/cfr/part040/part040-0022.html

Note 10CFR40.22(b) if your institution's activities are covered under an 
existing source material license.

[ RadSafe ] nonregulated Th






I am almost certain that 1 uCi of Thorium Oxalate is nonregulated but I
am having trouble verifying this in the regs.  Can someone point me in
the right direction to obtain this info? 

 

Thanks,
