Uranium Glass
Here is a photo of the antique uranium glass cups I mentioned in an earlier post. They are also called vaseline glass. If they are really vaseline glass, uranium is used to tint the glass the yellow-green color. Also, if they are real, they are supposed to fluoresce bright green under UV light. It gives off a tiny amount of alpha particles (helium-4 nucleus) from the uranium and beta particles (high energy electrons) from the decay products, but is at harmless levels.
