Radioactivity is the process by which certain unstable atoms or elements undergo spontaneous disintegration, or decay, in an effort to attain a more balanced nuclear state. This decay can result in the emission and propagation of energy through space or a substance, which may take the form of waves or particles. However, the primary definition of radioactivity is related to the process of atomic decay.
