    Californium-252 production diagram Californium-252 (Cf-252, 252 Cf) undergoes spontaneous fission with a branching ratio of 3.09% and is used in small neutron sources . Fission neutrons have an energy range of 0 to 13 MeV with a mean value of 2.3 MeV and a most probable value of 1 MeV.

  3. Californium neutron flux multiplier - Wikipedia

    en.wikipedia.org/wiki/Californium_neutron_flux...

    Rather than relying solely on a large amount of californium for neutrons, the multiplier effect of 3.5 pounds of uranium initiated by only a few milligrams of 252 Cf provided a higher ultimate neutron flux at a lower cost. The CFX was designed by IRT Corporation, [1] with two devices manufactured.

  4. Californium - Wikipedia

    en.wikipedia.org/wiki/Californium

    Californium is a silvery-white actinide metal [12] with a melting point of 900 ± 30 °C (1,650 ± 50 °F) and an estimated boiling point of 1,743 K (1,470 °C; 2,680 °F). [13] The pure metal is malleable and is easily cut with a knife. Californium metal starts to vaporize above 300 °C (570 °F) when exposed to a vacuum. [14]

  5. Neutron source - Wikipedia

    en.wikipedia.org/wiki/Neutron_source

    Some isotopes undergo spontaneous fission (SF) with emission of neutrons.The most common spontaneous fission source is the isotope californium-252. 252 Cf and all other SF neutron sources are made by irradiating uranium or a transuranic element in a nuclear reactor, where neutrons are absorbed in the starting material and its subsequent reaction products, transmuting the starting material into ...

    The most important isotopes of these elements in spent nuclear fuel are neptunium-237, americium-241, americium-243, curium-242 through -248, and californium-249 through -252. Plutonium and the minor actinides will be responsible for the bulk of the radiotoxicity and heat generation of spent nuclear fuel in the long term (300 to 20,000 years in ...
