Californium-252 was prepared for the first time in 1954 by Diamond, H; Magnusson, L.; Mech, J.; Stevens, C.; Friedman, A.; Studier, M.; Fields, P.; and Huizenga, J.
Californium applications - neutron source to start-up nuclear reactors (Cf-252) - neutron source for neutron diffraction instruments (Cf-252) - neutron source for neutron spectroscopy instruments (Cf-252) - raw material for the preparation of heavier chemical elements (Cf-249) - source for portable neutron activation instruments (Cf-252) - source for radiation therapy with neutrons (Cf-252) - source for neutron radiography (Cf-252) - source for moisture detectors (Cf-252) - source for gold and silver detectors (Cf-252) - source for analysis instruments of coals, cements etc. (Cf-252)
The most radioactive isotope known to date is Californium-252.
Californium is a highly expensive element, with estimated market prices around $25-30 per microgram. This makes it one of the most expensive elements in the world due to its rarity and complex production process.
I believe there is only one element named after a state, and that is Californium. However, there is in fact an element named Berkelium (check spelling?) that originates from Berkely, Calfornia.
