RE: Source for Uranium Nitrate
Dick is sensible. I wonder how many people I have sat next to on the bus who have diagnostic and even therapeutic radioactive isotopes in their bodies and sharing them with their fellow-travelers? How much radon do I consume every time someone kindly offers me a cool glass of water from his well? The list goes on... Few of us were yet born when workers refused to go into the factories that had those new Edison light bulbs? There are many real things to worry about, and I do not dismiss those lightly, but we need to keep a perspective on real dangers and not focus on the miniscule and trivia.

It now needs to be shipped as a radioactive substance in approved lead lined containers and all of that crap. I am not even sure if can go on airplanes. We quit shipping it several years ago. Cole Parmer used to carry it but they quit when the shipping went sky-high. http://www.coleparmer.com/catalog/product_view.asp?sku=00043XC You can see they discontinued it as well. I think it is all a big bunch of hooey. It is in fact slightly radioactive but only slightly. All the good bomb making stuff has already been taken out, and that makes logical sense. I have my own special horde of it, about 300 gms left that we can't sell, and I once showed the bottle to some students visiting and their professor freaked and virtually ran out of the room. Like most airport security, it's all show. --Dick Sullivan Mark Booth wrote: > I am seeking a good source for purchasing Uranium Nitrate for creating > a Uranium toner solution.
