As of 2003, the two sites produce 0.25 grams and 0.025 grams of 252 Cf per year, respectively. [57] Three californium isotopes with significant half-lives are produced, requiring a total of 15 neutron captures by uranium-238 without nuclear fission or alpha decay occurring during the process.

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.
Transuranic elements are difficult and expensive to produce, and their prices increase rapidly with atomic number. As of 2008, the cost of weapons-grade plutonium was around $4,000/gram, [2] and californium exceeded $60,000,000/gram. [3] Einsteinium is the heaviest element that has been produced in macroscopic quantities. [4]
