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 Cruiser Radium Cruiser The Radium Cruiser was a Russel Brothers tugboat operated on the Mackenzie River system for the "Radium Line". She was constructed in Owen Sound, Ontario, in 1939, then disassembled and shipped by rail to Waterways, Alberta. Waterways is a river port, and was then the northern terminus of the North American railway grid. Waterways is on the Clearwater River, not far upstream from where the river empties into Lake Athabasca. The waters of Lake Athabasca flow into Great Slave Lake down the Slave River, and then down the Mackenzie River to the Arctic Ocean. A 16 mile series
