Along with thorium, radium is found in uranium ore (pitchblende) as a decay product of uranium. It was first isolated in 1898 by Marie Curie, Pierre Curie, and Gustave Bemont, in Paris France. Smaller amounts have been extracted from the mineral carnotite (potassium uranium vanadate).

Radium is obtained from the residue of Uranium ores after the Uranium has been extracted. It may be of interest to know that Mme. Marie Curie needed 10 Tonnes (10 000Kg) of Pitchblende residue and 3 years of refining to produce 0.1 grammes of pure Radium Chloride.

Don't try this at home.

Today radium has only limited applications in research laboratories, for example for the preparation of radon standard solutions, in neutron sources of the type Ra-Be, etc.

Possible use in radiotherapy of some cancers.

Radium was used in the past for luminescent painting of watches and other instruments, was used in toothpaste, cosmetics, etc. These applications are not permitted now because radium is strongly radioactive and dangerous.

It is present in small amounts as a part of uranium ores (like pitchblende).

Why did Marie Curie discover polonium and radium?

Studying residues of uranium ores, Marie Curie and Pierre Curie found that these residues are more radioactive than uranium; they attributed this radioactivity to unknown elements. They isolated these elements and named these elements polonium and radium.
