Abstract
Based on data concerning the density of glasses, the mass fractions of the chemical elements that enter into the composition of the glasses, and their mass attenuation coefficients of photonic radiation with a quantum energy from 20 keV to 3 MeV, the linear x-ray and gamma-ray attenuation coefficients of typical optical and radiation-resistant glasses are calculated. The chemical elements in the composition of the glasses are indicated that have the maximum effect on the linear attenuation coefficient of photonic radiation by glasses of the crown and flint groups. The thicknesses of the layers of these glasses are determined that attenuate the γ radiation of the radionuclides Co60 (1.25 MeV) and Cs137 (0.661 MeV) to one-half and one-tenth.
