Radian Barite crystals up to 2,3 cm grown densely on the Quartz-porphyry (Paleoignimbrite) matrix. Due to comparatively short decay of Radium (226Ra half-life = 1600 years) the specimen indicates a minor radioactivity. At background of 0,080 µSv/h the α+β+γ radiation shows 0,252 µSv/h. Rare and unusual good specimen.
