Radium bromide the air causes this luminescence. Radium bromide is also very dangerous since the crystals occasionally explode. Helium gas evolved from alpha particles can accumulate within the crystals which cause them to weaken and rupture. Another property of radium bromide is its ability to crystallize from an aqueous solution. It forms a dihydrate, very similar to barium bromide. The chemical radium bromide is not found in nature; it is created. To extract radium from uranium or pitchblende ores, the most common practice is called the Curie method which it involves two major stages. The first stage is a chemical treatment to
Radium King King" was the first vessel to cross Great Slave Lake—arriving in Yellowknife on June 8. While the lake's ice had broken up, it hadn't moved out. Northern Transportation added additional vessels to her fleet, many of which, like the "Radium Charles" and "Radium Yellowknife" also bore the prefix "Radium", and the line was known locally as the "Radium Line". In 1956 the "Radium King" survived the explosion of mining supplies on a barge she was towing. In 1967 the boat was retired. Currently she is on display outside the Northern Life Museum in Fort Smith, Northwest Territories. The "Radium King"
