Radiation damage effects on the structure and properties of radioactive waste glasses

“…It is a technique that measures the absorption of radiation as a function of wavelength. It is a type of optical absorption technique in which the light of UV-Vis-nIR region (UV 190-400 nm, visible 400-800 nm, and near infrared 780-3300 nm) is absorbed or transmitted by the material [194,229,230]. This absorption results in the excitation of the electrons from the ground state to a higher energy state.…”
