Source Material
The conclusion is that any uranyl compound of reagent quality is "source
material.  A very quick look in merck tells me that most uranyl compounds
the U is in the 60% range.
The chem locker may need radioactive materials sticker!
We've gotten rid of all uranium compounds and my signature is needed for
any new purchases!
Cheers
