Are radioactive minerals on display?

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.
