摘要
A radiation shielding glass consisting esentially of 40.0% to 60.0% SiO.sub.2, 25.0% to 45.0% of PbO, 1.5% to 2.0% CeO.sub.2, 4.5% to 12.0% Na.sub.2 O, 2.0% to 9.0% K.sub.2 O, 0% to 5.0% B.sub.2 O.sub.3, and 0% to 10.0% BaO, Na.sub.2 O/(Na.sub.2 O+K.sub.2 O) being 0.5 to 0.8. The glass has a high radiation shielding capacity and is excellent in a resistance to browning by the gamma ray irradiation and an improved dielectric breakdown. The glass is useful for a window glass of an irradiation room of the gamma ray.
