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 Express (ship) Radium line were found to be free of contamination, with the exception of the "Radium Gilbert". The 2005 study said the "Radium Express" was being stored, in Hay River. Radium Express (ship) The Radium Express is a Russel Brothers tugboat operated by the Northern Transportation Company. The vessel was built in Owen Sound, Ontario, disassembled, and then shipped by rail to Waterways, Alberta, which was then the terminus of the North American railway grid. Like the other vessels in the "Radium Line", she was reassembled in Waterways, on the Clearwater River, a tributary of the Mackenzie, and then proceeded up
