Abstract
Radium is one of the very rare metal elements which would probably still be undiscovered but for the fact that it is very radioactive. It is almost always found in association with uranium, deposits of which occur in Canada, the Congo and USA. The principal source is the Canadian pitchblende deposits which also contain silver and copper with some nickel. The extraction and purification of the metal is a long drawn out complex process resulting in very little metallic radium from many hundred tons of ore.
