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.
Beta decay. Beta decay (Î² -decay) is the spontaneous inter-conversion of protons and neutrons. It occurs within the nucleus and is accompanied by the emission or absorption of electrons (e â) or positrons (e +) and neutrinos (ve) or antineutrinos (vÌe): (1) Electron Î² - -decay: n â p Î²- = e - + vÌe.pontaneous fission. Spontaneous fission is the spontaneous decay of heavy nuclei into two or, less frequently, three or four fragments, which are the nuclei of elements in the middle of the periodic system. Spontaneous fission and alpha decay limit the possibilities of obtaining new transuranium elements.
