A few weeks ago I found this radioactive ore in the "Schwarzwald" (Black Forest) in Germany. Since i found it i wanted to know what kind of ore it exactly was. I now strongly suggest it being Uranium because when I tried to dissolve it in 50% Sulfuric acid the acid was slightly fluorescing under ultraviolet light. The ore itself however shows no signs of fluorescens. Does anyone know what ore this might be or how to find out?
Thanks in advance.
