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 King Radium King The Radium King was built in 1937 to haul ore on the Mackenzie River, and her tributaries. This included uranium used in the US atom bombs of World War II. Later in her active career she hauled barges on Great Slave Lake. The "Radium King", and a sister ship, the "Radium Queen", were built in the Manseau shipyards in Montreal. They were then disassembled and the pieces were loaded on flatcars for shipment by railroad to Waterways, Alberta, which was then the northern terminus of the North American railway grid, to be reassembled and launched on the Mackenzie
