CHEM120 Week 6 Discussion: Radiation – Radioactive Isotope: Cobalt-60 (Option 1) Option 1 Cobalt-60 a. What type(s) of radioactive decay does your isotope undergo? Radioactive decay occurs when an unstable nucleus changes into a stable nucleus by emitting radiation. The cobalt-60 isotope undergoes a beta decay and produces gamma rays as it decays. The half-life for cobalt-60 is 5.27 years. This is how long the decaying process takes to get to Nickel-59, a more stable isotope ("Cancer Therapy,...
