RE: Surplus uranyl-nitrate - Let's Talk

["Caracappa, Peter F (CRD)" <caracappa@crd.ge.com>]

If I read my 10 CFR 40.13 correctly, I don't see anything about Uranyl Acetate being exempt, unless
it contains less than one twentieth of one percent of Uranium (which it certainly may).

And if it is less than 1/20 of 1% source material, as far as any regulation I can find, it can be
disposed of in an unregulated manner - which can cause a little trouble if your TSD has a really good
radiation detector.  We ran into this problem recently when we disposed of an air receiver that had
been used in a sandblasting operation, that was disposed of while full of the sand shot.  It got
rejected at the Port of Albany for radiation (about 100 microR on contact) - and what nobody noticed
until it was all over was the line hidden in the middle of the MSDS for the shot that said "this
material may contain up to 0.05% natural uranium and thorium compounds" and made reference to some
section of the California Sate Public Code.

So is there some other exemption for Uranyl Acetate/Nitrate that I am missing?  Is it maybe a state
regulation?

	 	Uranyl Acetate is EXEMPT.  This is a question for the group.  The
	chemical companies sell this stuff without any license required however,
	trying to get rid of it continues to pose problems.

		If it is exempt, why can't it be disposed as regular chemical waste?
	Why do we always have problems trying to dispose of it?

		As indicated in the message below, "...someone who is authorized to
	possess this material", anyone is authorized to possess it.  Anyone!

		Let's discuss this issue a little and see if we can reach a
	consensus about the proper and required disposal method for Uranyl
	acetate/nitrate.

	Louie Tonry, CHP

	Southwest Research has about 11 pounds of surplus uranyl-nitrate in unopened

	containers. If there is someone who is authorized to possess this material 
	and would like to recycle it, please call or email me at 210-522-2633 or 
	jph@swri.edu <mailto:jph@swri.edu> .

	Thanks, John P. Hageman, Radiation Safety Officer, Southwest Research 
	Institute.
