Q. What is 'Californium', recently seen in news?
Answer:
A highly radioactive element
Notes: Bihar police recently seized 50 grams of californium, a highly radioactive element. Californium is a synthetic, silvery-white metal with atomic number 98, first synthesized in 1950 at the University of California, Berkeley. It is not naturally occurring and is produced by bombarding curium with helium ions. It is known for its intense radioactivity. Californium is valuable but hazardous. It is used in starting nuclear reactors, detecting metal fatigue in airplanes, and treating certain cancers. Californium's isotopes include Cf-251, the most stable with a half-life of 898 years, and is used in various industrial and scientific applications.
