Kinetics of Radiation-Induced Optical Absorption Spectra in LPX-100, -200 Protective Glasses

The results of studies of the kinetics of radiation-induced optical absorption spectra of commercially produced glasses LPX-100 and -200 (Lemer Pax Co., France) after γ-irradiation to 1 MGy in the wavelength range 320–1000 nm are reported. The restoration of light transmission was monitored for 120 days. The linear coefficients of attenuation of γ-radiation by glasses were measured using a KRONA-II-04 γ-spectrometer with OSGI standard radiation sources 60Co (1.173 and 1.333 MeV) and 137Cs (0.661 MeV). The experimental data make it possible to determine with adequate accuracy the applicability of the studied glasses under other conditions of irradiation. A brief comparative analysis of the results obtained for TK100 and TF103 glasses by other authors is given.
