Radium is atomicnumber 88

  • Appearence: A radioactive metal found naturally in uranium ores. It was extracted from this source for many years for cancer treatment and for the luminous paint applied to clock and watch dials. Production is now as little as 100 grammes per year
  • Biological Role: Radium has no known biological role. It is toxic due to its radioactivity.
  • Natural Abundance: Radium is present in all uranium ores, and could be extracted as a by-product of uranium refining. The usual source of pitchblende comes from Bohemia, but some radium-containing ores are found in Canada and the USA. Annual production of this element is less than 100 grams
