Gamma radiation is a form of electromagnetic radiation. Gamma rays are high-energy (short-wavelength) photons. A gamma ray has no charge and no mass. When a gamma-ray photon is emitted from a radioactive atom, it does not change the mass number or the atomic number of the element. Gamma rays, are emitted in conjunction with other types of radiation. Lowest ionizing power, highest penetrating power. Positron Emission (composition, symbol, ionizing power, penetrating power)
