Abstract
Provided is a radiation-shielding glass, including a glass composition in % by mass of 10 to 35% SiO, 55 to 80% PbO, 0 to 10% BO, 0 to 10% AlO, 0 to 10% SrO, 0 to 10% BaO, 0 to 10% NaO, and 0 to 10% KO, in which the radiation-shielding glass has a total light transmission at a wavelength of 400 nm at a thickness of 10 mm of 50% or higher. Also provided is a radiation-shielding glass which has the similar glass composition and can be used for a gamma-ray shielding glass for a PET examination.
