    Autunite is a radioactive orthorhombic mineral which results from the hydrothermal alteration of uranium minerals. Used as a uranium ore, it was first discovered in France in 1852. Autunite is one of the more attractive and popular radioactive minerals.

    Because of this tendency of radioactive minerals to disappear, some of them are so rare that crystals cannot even be formed with them anymore. This means that the more common the naturally radioactive material, the less radioactive it likely is. A good comparison is with uranium, tritium, and Technetium-99. Uranium takes a very long time to ...

    Radioactivity in minerals are caused by the inclusion of naturally-occurring radioactive elements in the mineral's composition. The degree of radioactivity is dependent on the concentration and isotope present in the mineral. For the most part, minerals that contain potassium (K), uranium (U), and thorium (Th) are radioactive.

    The following is a non-exhaustive list of minerals containing radioactive isotopes of elements such as mainly: . uranium;; thorium;; potassium;; bismuth (the radioactive isotope, 210 Bi, is found as a daughter product of Pb210 from Th in thorium minerals).; These minerals emit alpha, beta and gamma ionising radiations, as well as radioactive gases such as radon and thoron.

    The mineral is also studied for its unique crystallization, which forms under specific environmental conditions. Despite its small size and limited use in mining, torbernite continues to be a popular specimen for collectors interested in radioactive minerals. #7: Uranophane - Size: 1.5 inches (3.8 cm)

    Radioactive minerals can be identified with special instruments that detect radiation. The device used to measure this is the Geiger counter. Electric charges develop in a Geiger counter when it is placed near radioactive material; this can measure the presence and intensity of radiation. Geiger counters are normally used by scientists and ...

    Radioactive minerals are quite rare but many of them, like those seen in Figure \(\PageIndex{1}\), make spectacular mineral specimens. Torbernite (copper-uranium phosphate), autunite (calcium-uranium phosphate), and uraninite (uranium oxide) are three of the most common examples. Uraninite is the main ore for uranium; the specimen seen here ...

    Radioactive minerals like uraninite, carnotite, autunite, and torbernite often have interesting structures and varying degrees of fluorescence.They can be interesting specimens in a rockhound's rock collection.Fortunately, with the appropriate equipment and safety protocols, it is possible to keep those radioactive rocks while keeping yourself out of harm's way.

    Radioactive minerals emit alpha, beta and gamma radiation. The amount of that radiation is best measured with Geiger counters or scintillation counters. Warning: If you collect or possess radioactive minerals, you really should have a means of measuring radiation to determine if the extraordinary precautions are needed to store the mineral.
