Californium - Cf

Californium (Cf)

Californium is a radioactive actinide produced in very small quantities. It does not have a standard atomic weight; the bracketed value below identifies a representative isotope mass number.

Uses and applications

Californium-252 is a strong neutron source used in specialised applications, including neutron activation analysis and some well-logging instruments. Californium sources require specialised shielding, containment, and radiation-safety controls.

Californium and water management

Californium is not a water-treatment reagent. Some californium neutron sources have been used in well logging to identify subsurface water and oil-bearing layers; this is a measurement application, not a water-purification process.

Occurrence and environmental context

Californium is a synthetic actinide with no stable isotopes. Its occurrence outside controlled production is extremely limited. Environmental assessment, if relevant, depends on isotope, activity, chemical form, and the specific source.

Health and safety

Californium requires specialised radiological controls. Exposure risk depends on isotope, activity, chemical form, and exposure route. Follow applicable radiation-protection procedures and institutional requirements when handling radioactive materials or waste.
