white-ish silvery.
The first name was radium; some isotopes had in the past other names.
Ra stands for Radium on the periodic table. Radium is a radioactive element with atomic number 88 and is commonly used in medicine for some cancer treatments.
Radium primarily forms compounds with oxygen, such as radium oxide (RaO), radium peroxide (RaO2), and radium hydroxide (Ra(OH)2). It can also form compounds with other elements, such as radium chloride (RaCl2) and radium sulfate (RaSO4). These compounds are generally highly radioactive due to the nature of radium as a radioactive element.
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.
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.
The first name was radium; some isotopes had in the past other names.
Possible use of radium isotopes for the radiotherapy of some cancers.
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
Ra stands for Radium on the periodic table. Radium is a radioactive element with atomic number 88 and is commonly used in medicine for some cancer treatments.
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).
Radium primarily forms compounds with oxygen, such as radium oxide (RaO), radium peroxide (RaO2), and radium hydroxide (Ra(OH)2). It can also form compounds with other elements, such as radium chloride (RaCl2) and radium sulfate (RaSO4).

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.
