Cobalt-60 - Wikipedia
60 Co undergoes beta decay to the stable isotope nickel-60 (60 Ni). The activated cobalt 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 − + 2 γ
Beta Decay Examples - HyperPhysics
Cobalt-60 decays to Nickel-60 plus an electron and an electron antineutrino. The decay is initially to a nuclear excited state of Nickel-60 from which it emits either one or two gamma ray photons to reach the ground state of the Nickel isotope.

Cobalt-60 is a nuclide that \(\beta^-\) decays in the following manner: \[\ce{^{60}Co \rightarrow ^{60}Ni + \beta^{-} + } \text{neutrino}.\] The neutrino is a particle emitted in beta decay that was unanticipated and is of fundamental importance. The neutrino was not ...
Cobalt-60 - Oncology Medical Physics
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.

Cobalt-60, a radioactive isotope, undergoes beta decay by transforming into an isotope of nickel, which is a more stable state. In practical applications, Cobalt-60 is widely used in radiation therapy to treat cancer, exploiting its beta decay property.
How does cobalt-60 change in the environment? Cobalt-60 decays by beta and gamma emission to non-radioactive nickel. Most of the radiation from the decay of cobalt-60 is in the form of gamma emissions; some is in the form of beta particles. Beta particles are generally absorbed in the skin and do not pass through the entire body. Gamma radiation,
