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 does not occur naturally. It is produced as a result of nuclear explosions and nuclear experiments.
Yes, californium is a pure chemical element, not a compound or mixture.
Not californium, but neutrons emitted by californium.
