Spectral, Radiation-Optical and Shielding Properties of Phosphate Glasses with High Lead Content

Abstract:

Spectral, radiation optical, and radiation shielding properties of new phosphate glasses, TPF, with high lead content (up to 40 mol. % PbO) were studied. They are characterized by the heightened radiation optical resistance at exposure doses up to 5*107 R, and by the improved radiation shielding properties as compared with similar data of silicate glasses with the same lead content. A TPF boundary of semi-transmission for a 1 cm thick glass layer lies approximately at 355 nm, its absorption coefficient, µ, for γ-quanta of 137Cs (0.663 MeV) and 60Co (1.25 MeV) reach 0.373 and 0.240 cm-1 whereas µ’s of the Russian radiation resistant strong flint TF110 (40 mol. % PbO) are equal to 0.355 and 0.214 cm-1. These properties allowed to use TPF instead of strong silicate flints as material for observation radiation schielding windows of facilities of special usage.
