californium
Synthetic actinide metal
Californium is a synthetic radioactive element, atomic number 98, produced in nuclear reactors and particle accelerators.
It belongs to the actinide series and has no stable isotopes.
Californium-252 is used as a neutron source in nuclear reactors, cancer treatment, and detecting gold and silver ores.
Named for California, where it was first synthesized in 1950.
