The most stable of californium's twenty known isotopes is californium-251, with a half-life of 898 years. This short half-life means the element is not found in significant quantities in the Earth's crust. 252 Cf, with a half-life of about 2.645 years, is the most common isotope used and is produced at Oak Ridge National … See more Californium is a radioactive chemical element with the symbol Cf and atomic number 98. The element was first synthesized in 1950 at Lawrence Berkeley National Laboratory (then the University of California Radiation … See more Californium was first made at University of California Radiation Laboratory, Berkeley, by physics researchers Stanley Gerald Thompson See more Californium is produced in nuclear reactors and particle accelerators. Californium-250 is made by bombarding berkelium-249 ( 97Bk ) with neutrons, forming berkelium-250 ( 97Bk ) via neutron capture (n,γ) which, in turn, quickly beta decays (β ) to californium-250 ( … See more Physical properties Californium is a silvery-white actinide metal with a melting point of 900 ± 30 °C (1,650 ± 50 °F) and an estimated boiling point of 1,745 K (1,470 °C; … See more Traces of californium can be found near facilities that use the element in mineral prospecting and in medical treatments. The element is … See more Californium-252 has a number of specialized uses as a strong neutron emitter; it produces 139 million neutrons per microgram per minute. This property makes it useful as a See more Californium that bioaccumulates in skeletal tissue releases radiation that disrupts the body's ability to form red blood cells. The element plays no natural biological role in any organism due … See more WebThe most stable is Cf-251 with a half-life of 898 years. Cf-249 has a half-life of 351 years, and Cf-250 has a half-life of 13 years. The remaining isotopic compounds only have half-lives no greater than 2.7 years. Most of those only have a half-life of less than 20 minutes.

This isotope decays with a half-life of 9 h producing the isotope C-250 which has a half-life of 19 days and can decay into Pu-251. This then decays into Am-241 which beta decays to produce neutrons. Californium could theoretically be used in self-powered lighting and pacemaker batteries. rain vfx
