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 bromide from such a large amount of material, it was difficult to find a large quantity of radium. This was the reason radium bromide became one of the most expensive materials on earth. It was desired by many all around the world and there was very little to go around. In 1921, it was stated in "Times" magazine that radium cost 17,000,000,000 Euros per ton compared to gold at 208,000 Euros and coal, as diamond, at 400,000,000 Euros. A common reason that radium was added into almost everything at the time, including water and toys, was that people saw radium as
