Large Active Radian-Barite Specimen from the Czech Republic
Large Active Radian-Barite Specimen from the Czech Republic
Description: Radian-Barite (aka Radiobarite) is is comprised of radium and barium sulfate. It is considered by some to be the “most radioactive substance found in nature” and webmineral.com in fact lists it as a whopping 444,528 mR/hour for 1000 grams.
However, since Radium has a half-life of about 1600 years, this level of activity is rarely found in mineral deposits. 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.
