About Californium

Californium is an actinide and a radioactive metal which was discovered about 70 years ago by a group of scientists in one of the universities of California, so it has got its name after the state. This chemical element is very toxic and has no biological importance. It can be produced in the lab from a type of plutonium. There are 20 isotopes of Californium, and this element can produce a few compounds. It is used in nuclear reactors and is highly valued for its property to emit neutrons. Californium can be used in various kinds of detectors used for a variety of purposes like identifying certain components of ores, detecting oil or water layers, detecting material fatigue, etc.
