Cobalt-60 (radioisotope)

Cobalt-60 is a radioactive isotope of cobalt, meaning it has an unstable nucleus that emits radiation as it decays. It is produced artificially in nuclear reactors and primarily used in medical treatments like cancer radiotherapy, as well as in industrial applications for sterilizing equipment and food. The radiation emitted is gamma rays, which can penetrate tissues or materials to destroy cancer cells or eliminate microbes. Despite its usefulness, handling Cobalt-60 requires strict safety precautions due to its radiation emission, which can be harmful if not properly managed.
