Radium chloride radium chloride is weakly paramagnetic with a magnetic susceptibility of 1.05. It also differs from barium chloride by the flame color, which is red as opposed to green for barium chloride. Radium chloride is still used for the initial stages of the separation of radium from barium during the extraction of radium from pitchblende. The large quantities of material involved (tonnes of ore for milligrams of radium) favour this less costly (but less efficient) method over those based on radium bromide or radium chromate (used for the later stages of the separation). It was also used in medicine to produce
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. Radium was also highly successful in led contests for the best type of Stock Horse. During WWII, at
