Unstable nucleus.<\/p>\n<p>Radioactivity is the process by which an unstable atomic nucleus loses energy by radiation. This radiation can take the form of alpha particles, beta particles, or gamma rays. The type of radiation emitted depends on the type of atom that is radioactive.<\/p>\n<p>Radioactivity is caused by the instability of the nucleus. The nucleus is made up of protons and neutrons, and these particles are held together by the strong nuclear force.
