Californium is a man made element; usually found in nuclear physics/radiochemistry laboratories.
Californium is a radioactive transuranic element, and is 'man-made'. Although it is not naturally occurring on earth, it does seem to come about in other places in the universe (pretty cool, huh?). It is used in starting nuclear reactors and medical treatment of cancer.
Californium is able to form a critical mass.
Californium is a metallic chemical element of the periodic table, found in the actinide family. It is used to start nuclear reactors, for oil exploration, and the treatment of cancer. Although "discovered" or "found" is not perhaps the correct term, as Californium does not exist naturally on earth, it is created. The synthetic radioactive metal, californium, was first created in 1950 by Albert Ghiorso, Kenneth Street Jr. and Stanley G. Thompson. It was named after the University of California and the state of California.
The first isotope of californium was discovered in 1950 at Berkeley Radiation Laboratories, California, USA.
