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-the spontaneous disintegration of a radioactive substance along with the emission of ionizing radiation. disintegration, decay. alpha decay-radioactive decay of an atomic nucleus that is accompanied by the emission of an alpha particle.beta decay-radioactive decay of an atomic nucleus that is accompanied by the emission of a beta particle.nuclear reaction - (physics) a process that alters the energy or structure or composition of atomic nuclei. 1  Facebook.2  Twitter.aÂ·diÂ·oÂ·acÂ·tive decay. The spontaneous breakdown of a radioactive nucleus into a lighter nucleus. Radioactive decay causes the release of radiation in the form of alpha particles, beta particles, or gamma rays. The end result of radioactive decay is the creation of a stable atomic nucleus.
