Californium is a radioactive element, which does not occur naturally on earth. Therefore it needs to be produced artificially. It is named after the city of Berkeley, California, where it was discovered. It is considered as one of the most expensive materials on earth: One gram of the isotope Californium-252 costs up to 60 million US$!
