60 Co undergoes beta decay to the stable isotope nickel-60 (60 Ni). The activated nickel nucleus emits two gamma rays with energies of 1.17 and 1.33 MeV, hence the overall equation of the nuclear reaction (activation and decay) is: 59 27 Co + n → 60 27 Co → 60 28 Ni + e − + ν e + gamma rays. See more Cobalt-60 ( Co) is a synthetic radioactive isotope of cobalt with a half-life of 5.2713 years. It is produced artificially in nuclear reactors.
