Properties of Radium

• Radium is an alkaline earth metal
• Radium has a melting point of 700C
• It has a boiling point of 1140C
• Pure, it is bright white, but it blackens upon
  exposure to air
• Decomposes in water
• It emits Alpha, Beta, and Gamma rays
• Produces neutrons when mixed with Beryllium
• 1 gram of Radium produces 0.0001 ml of radon gas
  a day, so it must be ventilated to prevent the
  build- up of such gas

Uses of Radium

• Is used to produce neutrons
• Used to make luminous paints
• Used in medical radioisotopes
• Also used as a gamma ray source
• One isotope, radium-226, is used commercially

4
Some Interesting Facts

• The name Radium comes from the Latin word radius,
  or ray
• Radium is found in pitchblende, or uraninite, and
  all uranium minerals
• The person who discovered it, Marie Curie, died
  later from being exposed to it.
• It was discovered in 1898 in France
