Effect of Elemental Composition of Glasses on the Methodology of Their Selection for Constructing Observation Radiation-Shielding Windows

A methodology for selecting glasses for constructing observation radiation-shielding windows (ORSWs) with a high attenuation multiplicity of photon ionizing radiation, acceptable transmittance, and an increased effective refractive index is proposed, which is based on taking into account the influence of the elemental composition of the glasses on their characteristics of X-ray and gamma radiation attenuation. It is suggested that it is advisable to design different types of ORSWs: for the energy ranges from 1.0 to 3.0 MeV and from 0.2 to 1.0 MeV, respectively. Two acceptable versions for ORSWs are proposed: a crown-flint version based on a pair of TKN1–TF200 glasses or a pure crown one on the base of TKN1 glass.
