A true rarity for all collectors of radioactive minerals, this is a fine tetragonal fergusonite crystal. One end shows a crystalline fracture while the other is flat terminated. Those prismatic tetragonal shaped crystals form at temperatures around 575 – 765°C otherwise they don’t disclose a crystal habit. This specimen is well sized and terrific shaped for this mineral species. The emitted radioactivity dosage for gamma particles is 1,6 µSv/h and include beta and alpha particles 4,8 µSv/h. A rare specimen from the Sakangyi area.
