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 Gilbert Radium Gilbert The Radium Gilbert was a tugboat built for transporting supplies to, and ore from, the radium and uranium mines in Canada's Northwest Territories. Like the other tugs in the Radium Line she was steel-hulled. She was named after Gilbert Labine, the prospector who discovered radioactive ore where Port Radium was built. She was built in Vancouver, in 1946 disassembled, so she could be shipped by rail to Waterways, Alberta. Like all vessels assembled in Waterways that operated on the Mackenzie River, and its tributaries, after she was reassembled she first proceeded downstream to Lake Athabasca, and down the
