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

Аннотация

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.
