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.
The first name was radium; some isotopes had in the past other names.
Radium chloride is a compound made of radium and chlorine. It is a radioactive substance known for its luminescent properties. Due to its high radioactivity, it is used in scientific research and medical applications, but must be handled with extreme caution.
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.
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.
The atomic mass of the radium isotope 226Ra is 226,025 409 8(25).
The first name was radium; some isotopes had in the past other names.
Radium is not used in asphalt.
Probably after 1910, for luminescent dial paints.
Radium chloride is a compound made of radium and chlorine. It is a radioactive substance known for its luminescent properties. Due to its high radioactivity, it is used in scientific research and medical applications, but must be handled with extreme caution.
Radium is not used to produce energy.
It isn't used for anything anymore--they have better, safer isotopes to do the things radium was once used for.
Radium was first discovered in an ore called pitchblende
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.
Polonium is not used for the treatment of cancers. Radium is used to treat bone cancers.
Radium was used in the past as a radioactive source in the radiotherapy of some cancers.
Radium was discovered in 1898 !
Radium is used today to treat Cancer and other medical caused deseases. It is also used in watch hands and gauges in airplanes. Radium is RADIOACTIVE and is not something to mess with.
