Radioactivity Radioactivity is the spontaneous emission of energy and particles from an unstable atomic nucleus. Atoms with unstable nuclei can undergo a process called radioactive decay, in which they release energy in the form of radiation as they try to become more stable. There are three common types of radiation emitted during radioactive decay: alpha particles, beta particles, and gamma rays. Alpha particles consist of two protons and two neutrons and are the least penetrating type of radiation. Beta particles are high-energy electrons or positrons and can penetrate deeper into materials than alpha particles. Gamma rays are high-energy electromagnetic radiation and are the most penetrating type of radiation. Radioactivity occurs naturally in certain elements, such as uranium and thorium, as well as in some isotopes of other elements. It can also be artificially induced in isotopes by bombarding them with particles in a process called nuclear activation. Radioactivity can have bot
