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 jaw American golfer and industrialist Eben Byers in 1932, after taking large doses of Radithor, a radioactive patent medicine containing radium, over several years. His illness garnered much publicity, and brought the problem of radioactive quack medicines into the public eye. "The Wall Street Journal" ran a story (in 1989 or after) titled "The Radium Water Worked Fine until His Jaw Came Off". Radium jaw Radium jaw is an occupational disease brought on by the ingestion and subsequent absorption of radium into the bones of radium dial painters and those consuming radium-laden patent medicines. The symptoms are necrosis of the mandible
