    • Discovery Location: Berkeley California United States
    • Discovery Year: 1950
    • Name Origin:
      After the state and University of California.
    • Abundance of Californium:
      • Earth's Crust/p.p.m.: N/A
      • Seawater/p.p.m.: nil
      • Atmosphere/p.p.m.: N/A
      • Sun (Relative to H=1E12): N/A
    • Sources of Californium:
      Made by bombarding curium with helium ions. World production is only around a few grams per year.
    • Uses of Californium:
      Californium is available only in very small quanities so its uses are limited, however, it is used in nuclear research as a source of fission fragments. It is also useful as a neutron sorce for activation analysis to detect gold or silver. It can also be used in moisture gauges in oil wells.
