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.
We have never stopped using radium. Many "trivial" uses and certain "inappropriate" medical uses were stopped decades ago. While many valid uses of radium have have stopped because better or safer materials (e.g. tritium, cobalt-60, caesium-137, promethium-147) have been found for those purposes, radium still has certain specialized medical and industrial uses where nothing else can yet take its place.
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.
Radium is a chemical element, not a compound.
Radium is not a common commercial product.
Radium chloride, RaCl2, was the first radium compound to be prepared in a pure state and was the basis of Marie Curie's original separation of radium from barium. The first preparation of radium metal was by the electrolysis of a solution of radium chloride using a mercury cathode.
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
Radium Cheung is 5' 8".

Now radium hasn't any use at home and in the industry.
There are 2 valence electrons in Radium. There are 2 valence electrons in Radium.
Marie Curie identified the element, Radium, and developed uses for that radioactive material.
