Uses & Benefits
- Currently known uses of Fermium metal are limited to research purpose only.
- It is used for research purpose. Very small amount of this metal is used in atomic batteries.
- Its radioactive decay is used for a phosphor to give off light. The light emitted is converted into electricity.
