Californium does not occur in nature, but it was discovered in 1950 by Stanley G. Thompson, Kenneth Street, Jr., Albert Ghiorso, and Glenn T. Seaborg at the University of California, Berkeley, as a product of the helium-ion bombardment of curium-242.			Uses - neutron source, source of fission fragments for research, moisture gauges for the determination of water and oil-bearing layers in oil wells
