单词	gamma radiation
释义	gamma radiation Electromagnetic radiation emitted by excited atomic nuclei during the process of passing to a lower excitation state. Gamma radiation ranges in energy from about 10-15 to 10-10 joule (10 keV to 10 MeV) corresponding to a wavelength range of about 10-10 to 10-14 metre. A common source of gamma radiation is cobalt–60: The de-excitation of nickel–60 is accompanied by the emission of gamma-ray photons having energies 1.17 MeV and 1.33 MeV
