Californium-252

Californium-252 is a man-made isotope that is produced in nuclear reactors. It has a relatively short half-life of 2.65 years. It emits alpha radiation, and is a strong emitter of neutrons.

Californium-252 has several medical and industrial applications, including its use in cancer therapy. It is also used to detect explosive devices in airline luggage. The alpha radiation emitted by californium-252 can be harmful to the human body if inhaled or ingested in large enough amounts, raising the risk of cancer.
