Radioactive decay
Large unstable atoms can become more stable by emitting radiation. This process is called radioactive decay. This radiation can be emitted in the form of a positively charged alpha particle, a negatively charged beta particle, or gamma rays or x-rays.

Radioactive decay
The spontaneous disintegration of certain atomic nuclei by emission of either 2 protons bound with 2 neutrons (a helium nucleus), known as alpha decay , or of an electron, known as beta decay . If the emitted beta particle is the antimatter positive electron the disintegration process is termed positron emission. Radioactive decay is sometimes accompanied by the emission of gamma rays and is always accompanied by the transmutation of the atomic nucleus into another element which is more stable. The rate of decay, known as the halflife , together with the energy of the emitted particle, is unique to the radionuclide (the species of unstable nucleus).
