Uses & Benefits
- Currently known uses of Nobelium metal are limited to research purpose only.
- Polonium metal has different Allotropes, it is used in antistatic devices and for research purpose.
- A 1 gram of Polonium can reach a temperature of 500°C, hence it is used as a heat source for space equipment.
