Probably after 1910, for luminescent paints.
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 in toothpaste, cosmetics, etc. These applications are not permitted now because radium is strongly radioactive and dangerous.
Probably in 1906, at Jachimov (Czech Republic), for water (containing natural radon) bathing.

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.
The first name was radium; some isotopes had in the past other names.
The name radium comes from a Latin word radius, which means ray. It was named this because the chemists found that photographic effects were similar at light rays.
Today radium-226 is not used for radiotherapy.
Radium is not used in asphalt.
Probably after 1910, for luminescent dial paints.

It isn't used for anything anymore--they have better, safer isotopes to do the things radium was once used for.
Radium is not used to produce energy.
Radium was first discovered in an ore called pitchblende
Today radium-226 is not used for radiotherapy.
Radium (Ra) atomic number 88
Polonium is not used for the treatment of cancers. Radium is used to treat bone cancers.
