Many thanks for the interesting formulas. This should useful when I need
to amuse myself during those cold winter months. BTW, the amount of
uranium nitrate retained by a print treated with it is very small, not enough
to make a GM survey meter react. (I know because I tried it on some
uranium prints and uranium-toned prints); however, a 100 gm bottle of the
stuff will make a counter dance a jig. It can be nasty stuff so all should
be careful with it so as not to ingest any or absorb any through ones
skin. i.e. keep your fingers out of any solution containing uranium nitrate
and don't breath in any "dust."
