Radioactivity
By: lilticklemeelmo_23
Radioactivity a.k.a. radioactive decay, is the steps taken in which the atomic nuclei of unstable isotopes release fast-moving particles and energy. There are three types of radioactive decay: (each based on which kind of radiation released by the nucleus) alpha decay, beta decay, and gamma decay.
Gamma rays, also called gamma radiation, are the most energetic radiation. In a radioactive isotope, the gamma rays come from the nucleus of the atom. There are two ways radiation can travel either as particles or waves. It does not change the atomic mass…
