The element is named after the university and state of California where its discovery took place.

One microgram of californium-252 can generate 170,000,000 neutrons per minute.

The element was not available in weighable amounts until ten years after its discovery due to minute production in the laboratory

Californium is a very strong neutron emitter. It is used in portable metal detectors, for identifying gold and silver ores, to identify water and oil layers in oil wells and to detect metal fatigue and stress in aeroplanes.
