divers use it to calculate how far below sea level they are, you also use them for temperature, and business(profit, loss, etc.)
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
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.

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.
radium-226 isa radioactive element and has the form of a pellet or solution housed with in a ceramic outer housing

Today radium has only very limited uses: - preparation of neutron sources, Ra-Be - preparation of radon standard solutions - studies in research laboratories Possible use in the future as source for the radiotherapy of some cancers.
