Uranium tile Uranium tile Uranium tiles have been used in the ceramics industry for many centuries, as uranium oxide makes an excellent ceramic glaze, and is reasonably abundant on the earth's crust. Not long after Henri Becquerel discovered radioactivity in uranium salts, Madame Curie discovered both polonium and radium as two new radioactive elements also present with uranium. The relatively high specific activity and moderate half-life of 1,600 years of Ra-226, the main radioisotope of radium found in uranium ore, made for a material which when mixed with a phosphor allowed for a glow-in-the-dark substance. Thus, in addition to its medical usage,
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.

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
