Radium chemicals and cause radioluminescence. Radium, in the form of radium chloride, was discovered by Marie and Pierre Curie in 1898. They extracted the radium compound from uraninite and published the discovery at the French Academy of Sciences five days later. Radium was isolated in its metallic state by Marie Curie and André-Louis Debierne through the electrolysis of radium chloride in 1911. In nature, radium is found in uranium and (to a lesser extent) thorium ores in trace amounts as small as a seventh of a gram per ton of uraninite. Radium is not necessary for living organisms, and adverse health
Radium Queen (ship) 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 "Radium Queen" towed barges from the railhead at Waterways, Alberta to a portage around the rapids. Cargo was unloaded there and transported by land, and loaded on barges on the lower river that were towed by the "Radium King", and later by
