Discovered in 1950 by scientists in UC Berkeley’s Radiation Laboratory, Californium-252 (Cf-252) has the second-highest atomic mass of all produced elements and is very radioactive. It is the only isotope to spontaneously emit neutrons, and these neutrons can be used in nuclear reactor start-ups, material scanners, and oil well logging.

By 1968, most of the Pu-242 had been irradiated and transmuted to curium-244 (or Cm-244). Actinides vs fission products Californium-252 Californium-252 (Cf-252, 252 Cf) undergoes spontaneous fission with a branching ratio of 3.09% and is used in small sized 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. Kalifornium (chemická značka Cf, latinsky Californium) je desátý člen řady aktinoidů, šestý transuran, silně radioaktivní kovový prvek, připravovaný uměle ozařováním jader curia, který se v přírodě nevyskytuje.. Pro kalifornium za běžného tlaku existují tři krystalické formy: jedna nad a jedna pod 900 ° C (1650 ° F). Třetí forma existuje při vysok Frontier Technology Corporation. 23 likes.

We are developing californium-252 sources for possible use in neutron therapy. This radionuclide with a half-life of 2.6 years emits 2.4 × 10 12 neutrons per second per gram by spontaneous fission.

Unique metal allows to shine through reactors, aircraft parts, and to detect damages that usually carefully hide from the X-rays. It helps to find reserves of gold, silver and oil in the ground.

This element acts as the richest source of neutrons and has been used widely in the industries where the neutron requirement is a higher one. The radioactive equipments that need a start-up by way of neutrons has been considered with the element. compuestas, dan al Cf-252 una clara ventaja sobre otros tipos de generadores de neutrones. Como notas favorables se mencionaron el coste de adquisición relativamente bajo, la fácil manipulación, el embalaje sencillo y un espectro bien definido.

Progress in Californium- 252 Neutron Brachytherapy 35 Initially, Cf-252 was produced at HFIR/REDC from the neutron irradiation of Pu-242.

Californium-252 promises to be an effective radium substitute in brachytherapy. In certain situations, such as cancer of the uterus, the dose rate near a linear source may be of interest. Paterson and Parker have tabulated the number of milligram hours for various active lengths of radium sources to give 1000 rad at different distances from the centre of the source.
