Gamma ray (also called gamma radiation), denoted by the lower-case Greek letter gamma (Î³ or Î³ {\displaystyle \gamma } ), is penetrating electromagnetic radiation of a kind arising from the radioactive decay of atomic nuclei and consists of high-energy photons.
Unlike alpha and beta particles, which have both energy and mass, gamma rays are pure energy. Gamma rays are similar to visible light, but have much higher energy. Gamma rays are often emitted along with alpha or beta particles during radioactive decay. Gamma rays are a radiation hazard for the entire body. They can easily penetrate barriers that can stop alpha and beta particles, such as skin and clothing. Gamma rays have so much penetrating power that several inches of a dense material like lead, or even a few feet of concrete may be required to stop them.
