Radium seventh of a gram of radium. One kilogram of the Earth's crust contains about 900 picograms of radium, and one liter of sea water contains about 89 femtograms of radium. Radium was discovered by Marie Sklodowska-Curie and her husband Pierre Curie on 21 December 1898, in a uraninite (pitchblende) sample. While studying the mineral earlier, the Curies removed uranium from it and found that the remaining material was still radioactive. They separated out an element similar to bismuth from pitchblende in July 1898, that turned out to be polonium. They then separated out a radioactive mixture consisting mostly of two
Badoit radium-226 and 713 Bq/m3 of radium-228. After treatment, it contains 5.45 mg/m3 of uranium, 28 Bq/m3 of radium 226 and 44 Bq/m3 of radium 228. Badoit Badoit is a brand of mineral water obtained from natural sources at Saint-Galmier, France. The water is naturally carbonated, on its journey through granite rocks and subterranean gas deposits. Badoit is named after Auguste Badoit, who began bottling the water of Saint Galmier in 1838. In 1971, Badoit became part of Evian SA, which later became a fully owned subsidiary of Boussois Souchon Neuvesel. Today, Badoit is a product and brand of the Danone
