Large Active Radian-Barite Specimen from the Czech Republic

Description: Radian-Barite (aka Radiobarite) is is comprised of radium and barium sulfate.  This large specimen (over 2700 grams) came from Lahošť (Jeníkov), Duchcov (Dux), Ústí Region, Bohemia (Böhmen; Boehmen) in the Czech Republic. This location is known for its Radium-Barite deposits. As shown above, the dark brown crystals of the material are readily identified by a Gamma spectrometer as Ra-226.  This type of large specimen is rarely seen on the market.
