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 jaw Theodor Blum, in 1924, who described an unusual mandibular osteomyelitis in a dial painter, naming it "radium jaw". The disease was determined by pathologist Dr. H.S. Martland in 1924 to be symptomatic of radium paint ingestion, after many female workers from various radium paint companies reported similar dental and mandibular pain. Symptoms were present in the mouth due to use of the lips and tongue to keep the radium-paint paintbrushes properly shaped. The disease was the main reason for litigation against the United States Radium Corporation by the Radium Girls. Another prominent example of this condition was the death of
