Uranium mining Cornwall. The first deliberate mining of radioactive ores took place in Jáchymov, a silver-mining city in the Czech Republic. Marie Curie used pitchblende ore from Jáchymov to isolate the element radium, a decay product of uranium. Until World War II uranium was mined primarily for its radium content; some carnotite deposits were mined primarily for the vanadium content. Sources for radium, contained in the uranium ore, were sought for use as luminous paint for watch dials and other instruments, as well as for health-related applications, some of which in retrospect were certainly harmful. The byproduct uranium was used mostly as
Uranium – Twisting the Dragon's Tail Uranium – Twisting the Dragon's Tail Uranium – Twisting the Dragon's Tail is a television documentary series about uranium, its history, and its uses. It was produced by Gene Pool Productions for PBS and SBS and premiered on both networks in late July and August 2015. The series was conceived, created, written and directed by Wain Fimeri, was shot in nine countries and is presented by Derek Muller. Derek Muller introduces uranium and its use throughout history. Uranium, originally sourced from pitchblende, became the subject of intense scientific study. Using computer-generated dragons as a metaphor for daughter isotopes, the episode
