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 Cruiser Radium Cruiser The Radium Cruiser was a Russel Brothers tugboat operated on the Mackenzie River system for the "Radium Line". She was constructed in Owen Sound, Ontario, in 1939, then disassembled and shipped by rail to Waterways, Alberta. Waterways is a river port, and was then the northern terminus of the North American railway grid. Waterways is on the Clearwater River, not far upstream from where the river empties into Lake Athabasca. The waters of Lake Athabasca flow into Great Slave Lake down the Slave River, and then down the Mackenzie River to the Arctic Ocean. A 16 mile series
