標 本 名: | ジルコン (Zircon- Hf)
| 化学組成: | ZrSiO4 (ca. 7% HfO2) | サ イ ズ: | | 重量: | | 透明: | | 数量: | | 産地: | Kyauk Pyat That, west of Mogok, ビルマ(ミャンマー) Burma (Myanmar) | This is an unusual radioactive zircon. The crystal or aggregate has geode-like shape with one round surface one face with radial pattern. This zirconium silicate is rich in Hafnium (around 7 percent). The radiation is caused by Uranium and Thorium content. The gamma radiation is 3 µSv/h and the total dosage is 2,7 µSv/h.
