Uses & Benefits
- Technetium is a radioactive metal and hence it is used for medical studies and other research purposes.
- 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.
