| Applications | Californium is a byproduct of plutonium production. Two of the californium isotopes (Cf-249 and Cf-251) have half-lives longer than 20 years and are defined as transuranic wastes (TRU) produced in nuclear reactors. Of the ten known isotopes, only Cf-252 is used commercially in industrial radiography and in brachytherapy to treat cancer. About 3% of decays are by spontaneous fission producing neutrons and gamma rays. Cf-252 is a strong emitter of neutrons at a rate of 170 million neutrons per minute, The only californium isotope that has a commercial use is californium-252. Because this radionuclide is only available in very small quantities its uses are quite limited. Californium-252 is a very strong neutron emitter, with one microgram emitting 170 million neutrons per minute. Thin foils containing californium-252 can be used as a source of fission fragments for research purposes. Californium-252 can also be used as a portable neutron source to identify gold or silver ores through neutron activation analysis, and it can be used in moisture gauges to locate water and oil-bearing layers in oil wells. In addition, californium-252 is used in brachytherapy to treat various types of cancer |
