Explanation:

Cobalt therapy or cobalt-60 therapy is the medical use of gamma rays from the radioisotope cobalt-60 to treat conditions such as cancer. Gamma radiation is widely used for sterilization of medical products. Cobalt-60 is the main isotope used since it is an energetic gamma emitter. Half life of cobalt 60 is only 5.26 years and thus it can‘t be used for radio-active dating.
