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 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
