標 本 名: | トール石 (トーライト ) (Thorite)
| 化学組成: | (Th,U)SiO4 | サ イ ズ: | | 重量: | | 透明: | | 数量: | | 産地: | secondary deposit: Onh Bin Yee Htwet , Le-Oo (Le U), northeast of Mogok, primary source might be: Oh Saung Taung, Le-Oo (Le U) ビルマ(ミャンマー) Burma (Myanmar) | Well this is a great Thorite crystal. Rarely seen in such shape and size. The crystal discloses a very sharp but distorted shape with very good preserved termination. Apart from the base no damages are present. The surface discloses some etching marks. The emitted dosage only for gamma particles is 18 µSv/h. All three particles together the dosage is 45 µSv/h. The crystal should be handled with care. This is a true rarity for all radioactive mineral collectors.
