There are several, of which the radioactive ones I have all fluoresce various shades of green.
I have Autunite, Andersonite, Schroeckingerite, which are all uranium salts. There are many other minerals (Quartz/Chalcedony/Onyx/Agate/Opal) that fluoresce green due to trace amounts of uranium salts in the mineral...
None of my minerals are at all dangerous. The amount of radioactivity given off is pretty low... Would I have them next to my pillow at night? Nope. But are they dangerous? Nope.
