Industry:Mining
High-energy, short-wavelength, electromagnetic radiation emitted by a nucleus. Energies of gamma rays are usually between 0.010 and 10 million eV. X-rays also occur in this energy range but are of nonnuclear origin. Gamma radiation usually accompanies alpha and beta emissions and always accompanies fission. Gamma rays are very penetrating and are best attenuated by dense materials like lead and depleted uranium.
