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 Ore Revigator with water overnight, which would be irradiated by the uranium and radium in the liner, and then consumed the next day. This was marketed as a healthy practice which could prevent illnesses including arthritis, flatulence, and senility. The Revigator contained carnotite K(UO)(VO)·3HO. Water stored overnight in a vintage Revigator was analyzed by ICP/MS and radiation detectors. Although the water contained higher levels of radon, the health risk from radiation was low. Even so, the water contained detectable levels of arsenic, lead, vanadium, and uranium. Radium Ore Revigator The Radium Ore Revigator was a pseudoscientific medical device consisting of a ceramic
