WebWhat is the decay process of cobalt-60? 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. WebThe decay scheme shows the transition from a high to a lower energy state and the alteration of the composition of the atomic nucleus. The atomic number (number of protons in the atomic nucleus) for cobalt changes to the atomic number of nickel due to the emission of a negatively charged beta particle and neutron is transformed to a proton.
