Uraninite named, was either unknown, impossible or not economically feasible). The mineral has been known at least since the 15th century from silver mines in the Ore Mountains, on the German/Czech border. The type locality is the historic mining and spa town known as Joachimsthal, the modern day Jáchymov, on the Czech side of the mountains, where F. E. Brückmann described the mineral in 1772. Pitchblende from the Johanngeorgenstadt deposit in Germany was used by M. Klaproth in 1789 to discover the element uranium. All uraninite minerals contain a small amount of radium as a radioactive decay product of uranium. Marie
Naturally occurring radioactive material UK regulation is via the Environmental Permitting (England and Wales)Regulations 2010. This defines two types of NORM activity: (a)the production and use of thorium, or thorium compounds, and the production of products where thorium is deliberately added; or (b)the production and use of uranium or uranium compounds, and the production of products where uranium is deliberately added (a)the extraction, production and use of rare earth elements and rare earth element alloys; (b)the mining and processing of ores other than uranium ore; (c)the production of oil and gas; (d)the removal and management of radioactive scales and precipitates from equipment associated with
