Uses & Benefits
- Californium metal has a very strong neutron emitter. It is used as a metal detector.
-
It also used as an identifier to check Water and oil layers in oil wells.
- It is also used in insecticides, hair dyes and as an anti-knocking additive for petrol. But all these are banned by the government as Lead metal is known for detrimental to health.
