Gamma rays

Gamma rays are more penetrating rays.  Gamma rays are electromagnetic radiation and other two type of natural radioactivity are alpha and beta radiation. Gamma radiation is the product of radioactive atoms. Gamma-rays were first observed in 1900 by French chemist Paul Villard.  Gamma-rays are produced primarily by four different nuclear reactions: Fusion, Fission, Alpha, Decay and Gamma Decay.
