Radium of radium Curie used the residues after extraction of uranium from pitchblende. The uranium had been extracted by dissolution in sulfuric acid leaving radium sulfate, which is similar to barium sulfate but even less soluble in the residues. The residues also contained rather substantial amounts of barium sulfate which thus acted as a carrier for the radium sulfate. The first steps of the radium extraction process involved boiling with sodium hydroxide followed by hydrochloric acid treatment to remove as much as possible of other compounds. The remaining residue was then treated with sodium carbonate to convert the barium sulfate into
Radium Hot Springs Radium Hot Springs Radium Hot Springs, informally and commonly called Radium, is a village of 776 residents situated in the East Kootenay region of British Columbia. The village is named for the hot springs located in the nearby Kootenay National Park. From Banff, Alberta, it is accessible via Highway 93. The hot springs were named after the radioactive element when an analysis of the water showed that it contained small traces of radon which is a decay product of radium. The radiation dosage from bathing in the pools is inconsequential; approximately from the water for a half-hour bathing, around ten
