Nuclear Decay Definition. Nuclear decay or radioactive decay is the emission of energy and matter because of change in the nucleus of atom. The nuclear decay involves the emission of ionizing particles or ionizing radiation.
Radioactive decay, also known as nuclear decay or radioactivity, is the process by which a nucleus of an unstable atom loses energy by emitting radiation.A material that spontaneously emits such radiation â which includes alpha particles, beta particles, gamma rays and conversion electrons â is considered radioactive. decay, or loss of energy from the nucleus, results when an atom with one type of nucleus, called the parent radionuclide (or parent radioisotope), transforms into an atom with a nucleus in a different state, or with a nucleus containing a different number of protons and neutrons.
