3 Uses
3.1 Uses & Benefits
  • It is a highly radioactive metal; and sometime Radium-223 is used to treat prostate cancer.
  • It is used in luminous paints.
  • Magnets of Samarium cobalt alloy are stronger than that of Iron and hence, they are used in microwave application.
  • Samarium metal also used in optical lasers and infrared absorbing glasses and as a neutron absorber.
