Radium exist in extremely low concentrations in uranium and thorium ores.
Radium was used in the past as a radioactive source in the radiotherapy of some cancers.
In the past radium was used for the radiotherapy of some cancers or as a component of luminescent paintings. Now radium has very limited uses: source of neutrons as Ra-Be, source of radon, research laboratories.
Today radium hasn't many important uses: - radium-beryllium neutrons sources - radium solutions as radon source and standards - possible use in the radiotherapy of some cancers
Polonium was used as source of energy in thermoelectric generators.
As alpha source E. Rutherford used radium.
Because radium is a decay product of uranium or thorium.
Polonium applications: - neutron source (polonium-beryllium source) - in devices for the elimination of the static electricity - in devices for the elimination of the dust - initiator in nuclear weapons - isotopic heat source Radium has not today practical applications.
The Curie couple brought the source (pitchblende) from North Bohemia
Polonium is used in radioisotope thermoelectric energy sources.
Radium: treatment by radiotherapy of some cancers, luminescent paintings for dials, neutron source as Ra-Be, uses in research laboratoryPolonium: radioactive heat source, neutron source as Po-Be, devices to eliminate dust and static elecrtricity, neutron trigger in nuclear weapons, uses in research laboratory
Radium is most commonly combined with beryllium, to create a neutron source for various applications such as in neutron radiography and in some types of cancer treatment. Combining radium with other elements can be dangerous due to its highly radioactive nature.
Marie and Pierre Curie were co-discoverers of radium. Over the years they worked unprotected with pitch-blend (the source of radium), and she eventually developed cancer.
