Radium bromide the air causes this luminescence. Radium bromide is also very dangerous since the crystals occasionally explode. Helium gas evolved from alpha particles can accumulate within the crystals which cause them to weaken and rupture. Another property of radium bromide is its ability to crystallize from an aqueous solution. It forms a dihydrate, very similar to barium bromide. The chemical radium bromide is not found in nature; it is created. To extract radium from uranium or pitchblende ores, the most common practice is called the Curie method which it involves two major stages. The first stage is a chemical treatment to
Radium Queen (ship) all but one of the surviving vessels of the Radium line were found to be free of contamination, with the exception of the "Radium Gilbert", but whether the "Radium Queen" had been contaminated could not be determined, as she had been scrapped. Radium Queen (ship) The Radium Queen and her sister ship the "Radium King" were built in Sorel, Quebec in 1937, for the Northern Transportation Company, a subsidiary of Eldorado Gold Mines. The "Radium Queen" was a cargo/tug ship that served on the Slave River. It made runs between Lake Athabaska and Great Slave Lake is generally navigable. The
