Background. Cobalt-60 (60 Co) is a synthetic radioisotope that has been used in both external beam radiation therapy and brachytherapy.60 Co decays via (beta) decay to an excited state of Nickel-60 which then emits two high energy (1.17MeV and 1.33MeV) gamma-rays. It is these energetic gamma rays which are primarily important for use in radiation therapy.
