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 is the process in which an unstable atomic nucleus spontaneously loses energy by emitting ionizing particles and radiation. This decay, or loss of energy, results in an atom of one type, called the parent nuclide transforming to an atom of a different type, called the daughter nuclide.
