Uses
Uses & Benefits
  • Currently known uses of Nobelium metal are limited to research purpose only.
  
  • Strontium metal is used to producing ferrite magnets as well as refining zinc.
  • By-product of nuclear reactors called Strontium-90 is a radioactive isotope; it is absorbed by tissues and destroys bone marrow and cancer growth.
