Due to safety concerns, we do not have radioactive minerals on display. However, the MGMH does have radioactive minerals in its collection, which are all stored in a thickly walled radioactive storage room designed to minimize potentially harmful exposure to radioactivity. Minerals in the radioactive collection include world famous uraninite crystals from the Swamp #1 Quarry in Topsham, Maine as well as other top specimens such as autunite from the Daybreak Mine in Washington, and torbernite from Cornwall, England and Katanga, Zaire.
