    en.wikipedia.org/wiki/Autunite Autunite (hydrated calcium uranyl phosphate), with formula Ca(UO 2) 2 (PO 4) 2 ·10–12H 2 O, is a yellow-greenish fluorescent phosphate mineral with a hardness of 2– 2 1 ⁄ 2. Autunite crystallizes in the orthorhombic system and often occurs as tabular square crystals, commonly in small crusts or in fan-like masses.Due to the moderate uranium content of 48.27% it is radioactive and also ...
