Uses & Benefits
- In some nuclear reactors sodium is used as a heat exchanger.
- Compound of Sodium metals called Salt (Sodium chloride) is used in Food.
- 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.
