white-ish silvery.
The first name was radium; some isotopes had in the past other names.
1. Radium was used in the past for the radiotherapy of some cancers. 2. But because radium is strongly radioactive uncontrolled irradiation or contamination with radium can lead to some cancers.
Radium is a natural chemical element, an alkali earth metal; but some isotopes of radium can be obtained artificially.
Some compounds of radium: RaF2, RaCl2, RaI2,RaBr2, RaO, Ra3N2, Ra(OH)2, etc.
Radium is not a common commercial product.

Possible use of radium isotopes for the radiotherapy of some cancers.
Radium is a natural chemical element, an alkali earth metal; but some isotopes of radium can be obtained artificially.
Radium was used in the past as a radioactive source in the radiotherapy of some cancers.
Radium exist in very small concentrations in some meteorites.
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
Some compounds of radium: RaF2, RaCl2, RaI2,RaBr2, RaO, Ra3N2, Ra(OH)2, etc.
Radium is not a common commercial product.
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 rarely in toothpaste, cosmetics, etc. These applications are not permitted now because radium is strongly radioactive and dangerous.
Today radium is not so important for practical applications: - radium-beryllium neutron sources - preparation of radon standard solutions - possible use in radiotherapy for some cancers
Radium was used in the past for the radiotherapy of some cancers, because radium is radioactive and emit gamma rays (also alpha and beta particles).
