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 Girls to release their data. At the urging of the companies, worker deaths were attributed by medical professionals to other causes. Syphilis, a notorious sexually transmitted infection at the time, was often cited in attempts to smear the reputations of the women. The inventor of radium dial paint, Dr. Sabin A.
