Radium bromide Institute had four grams of radium total, which at the time was more than half the world supply. Countries all over the world set out to make as much radium as possible, a time consuming and expensive task. It was reported in "Science" magazine in 1919 that the United States had produced approximately 55 grams of radium since 1913, which was also more than half the radium produced in the world at the time. A principal source for radium is pitchblende, which holds a total of 257 mg of radium per ton of UO. Obviously with so little product recovered
Radium bromide those two chemicals are chosen for the fractional crystallization. Once the radium is separated, radium bromide can be formed by dehydrating the dihydrate with a dry air stream at 200°C. Another method is to heat radium chloride to red heat with a dry hydrogen bromine gas stream. Radium and radium salts were commonly used for treating cancer. However, many treatments that were used in the early 1900s are not used anymore because of the harmful effects radium bromide exposure caused. Some examples are anaemia, cancer, and genetic mutations. Health effects from harmful amounts of radium exposure are tricky to diagnose
