Radian Barite
Item number: MIN0361
Price: EUR 125.00
Smaller tabular, yellow brown slightly translucent Radian Barite crystals up to 0,9 cm grown 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 0,080µSv/h the α+β+γ radiation shows 0,323 µSv/h.
