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.adioactive decay is a stochastic (i.e. random) process at the level of single atoms, in that, according to quantum theory, it is impossible to predict when a particular atom will decay.
  Radioactive decay is a natural process that occurs because a given atomic nucleus is unstable. The instability in the nucleus will eventually result in some kind of nucl â¦ ear change (depending on the atom), and we call this radioactive or nuclear decay.adioactive decay is the spontaneous change or disintegration of an unstable atomic nucleus as it transforms itself to lose energy.
