Abstract

Density changes of simulated radioactive waste glasses, silica glass and Pyrex glass irradiated by an electron accelerator were measured by a "sink-float" technique. The density changes of the waste and silica glasses were less than 0.05%, irradiated at 2.0 MeV up to the fluence of 1, 7 × 10¹⁷e/cm², while were remarkably smaller than that of Pyrex glass of 0.18% shrinkage, Precision of the measurements in the density changes of the waste glass was lower than that of Pyrex glass possibly because of the inhomogeneity of the waste glass.
