Please don't fool with HF. I don't know you, reader, but I like you anyway. Bringing uranium into your life almost certainly won't yield the cerebral joy you might imagine. Once you have it, it is a liability and a social responsibility until you can dispose of it safely, probably at substantial cost. If you feel the need to purchase a radioactive source, a sealed source will be much safer and readily transferred/disposed-of. I've worked with HF and spent about a year coordinating the safe cleanup of someone else's uranium oxide. If offered $19 and the choice to buy a gram of yellowcake or a bottle of wine from the grocery store, I'll choose the bottle of wine every time. Seriously; neither one is worth fooling with unless absolutely necessary. (A tungsten cube on the other hand....)
