Radium bromide

Radium bromide is the bromide salt of radium, with the formula RaBr2. It is produced during the process of separating radium from uranium ore. This inorganic compound was discovered by Pierre and Marie Curie in 1898, and the discovery sparked a huge interest in radiochemistry and radiotherapy. Since elemental radium oxidizes readily in air and water, radium salts are the preferred chemical form of radium to work with. Even though it is more stable than elemental radium, radium bromide is still extremely toxic, and can explode under certain conditions.
