Inhalation, injection, or body exposure to radium can cause cancer and other body disorders. Stored radium should be ventilated to prevent build-up of radon. Lead is a final product of disintegration. Radium loses about 1% of its activity in 25 years, being transformed into elements of lower atomic weight. Some of these sources are much more powerful, and others are safer to use.
Some of the more recently discovered radioisotopes, such as 60Co, are now being used in place of radium.

Radium is used in the producing of self-luminous paints, neutron sources, and in medicine for the treatment of disease. This is purged from the radium and sealed in minute tubes, which are used in the treatment of cancer and other diseases.
One gram of radium produces about 0.0001 ml (stp) of emanation, or radon gas, per day. Twenty five isotopes are now known radium 226, the common isotope, has a half-life of 1600 years. The curie is defined as that amount of radioactivity which has the same disintegration rate as 1 g of 226Ra. One gram of 226Ra undergoes 3.7 x 10 10 disintegrations per s. Atomic Symbol Ra Name Origin Latin: radius (ray). Sources Found in uranium ores at 1 part per 3 million parts uranium. Uses Used in treating cancer because of the gamma rays it gives off. Radium emits alpha, beta, and gamma rays and when mixed with beryllium produce neutrons. 226,0254 Learn more about the atomic mass. Radium imparts a carmine red color to a flame. It is a member of the alkaline-earth group of metals. It exhibits luminescence, as do its slats it decomposes in water and is somewhat more volatile than barium. The pure metal is brilliant white when freshly prepared, but blackens on exposure to air, probably due to formation of the nitride. Radium is obtained commercially as bromide and chloride it is doubtful if any appreciable stock of the isolated element now exists. Large uranium deposits are located in Ontario, New Mexico, Utah, Australia, and elsewhere. Radium is present in all uranium minerals, and could be extracted, if desired, from the extensive wastes of uranium processing. The carnotite sands of Colorado furnish some radium, but richer ores are found in the Republic of Zaire and the Great Lake region of Canada. In Chocolate Food products containing radium, like the Radium Schokolade chocolate bar manufactured by Burk & Braun and Hippman-Blach bakery’s Radium Bread, made with radium water, were. Originally, radium was obtained from the rich pitchblende ore found in Joachimsthal, Bohemia. Curie and Debierne by the electrolysis of a solution of pure radium chloride, employing a mercury cathode on distillation in an atmosphere of hydrogen this amalgam yielded the pure metal. There is about 1 g of radium in 7 tons of pitchblende. Curie in the pitchblende or uraninite of North Bohemia, where it occurs. radius, ray) Radium was discovered in 1898 by Mme.
