WebThe anhydrous compound can be prepared by the action of fluorine on thorium metal or thorium carbide, or by the action of anhydrous hydrogen fluoride on various thorium compounds. Ammonium hydrogendifluoride, NH 4 HF 2 will react with thorium dioxide to give the ternary fluoride NH 4 ThF 5: this decomposes at 300 °C to give ThF 4. WebThere are a significant number of lenses produced from the 1940s through the 1970s that are measurably radioactive. Main source of radioactivity is the use of thorium oxide (up to 30% by weight) as a component of the glass used in the lens elements. Thorium oxide has a crystalline structural similar to calcium fluoride (fluorite). Like fluorite, its optical …
