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 (horse) campdrafting without a bridle. In circa 1928, Radium was sold to Herb O’Neil, who, as a friend of Donald Beaton, had ridden the horse in competitions for Beaton when he had been unable to get away from his property. Herb O’Neill competed extensively with Radium, winning over a large area of the state. Just prior to the Second World War (WWII), Radium won a Championship Campdraft at Kempsey, New South Wales with the next ten placings going to Radium’s sons and daughters.
