Californium a nuclear explosion. Californium is not a major radionuclide at United States Department of Energy legacy sites since it was not produced in large quantities. Californium was once believed to be produced in supernovas, as their decay matches the 60-day half-life of Cf. However, subsequent studies failed to demonstrate any californium spectra, and supernova light curves are now thought to follow the decay of nickel-56. The transuranic elements from americium to fermium, including californium, occurred naturally in the natural nuclear fission reactor at Oklo, but no longer do so. Californium is produced in nuclear reactors and particle accelerators. Californium-250 is
Californium (video game) Californium (video game) Californium is an exploration game co-developed by Darjeeling and Nova Productions, and released in February 2016 for Microsoft Windows and OS X. "Californium" was developed as a tribute to science-fiction author Philip K. Dick on the 30th anniversary of his death.
