Radium is the element discovered my Marie and Pierre Curie in 1898. Based in Northern Bohemia, they found the element naturally in deposits of pitchblende. To isolate radium Curie used radium chloride and the process of electrolysis with a mercury cathode. Once distilled through hydrogen a pure white metal was discovered. Marie Curie earned two Nobel prizes for her research on Radium focusing primarily on its radioactive nature.
Radium is used in radiotherapy for treatments of cancer with a half life of only four days. Currently deposit sites have been found in the Carnotite sands of Colorado, the Democratic Republic of Congo and Great Bear Lake in Canada.Learn more about Chemistry
