<p>A radiation shielding glass that consisting of a Bi<SUB>2</SUB>O<SUB>3</SUB> glass with no lead content, exhibits a shielding capability equal to or superior to that of lead glass. There is provided a radiation shielding glass containing, by mol%, 0.5 to 80% of Bi<SUB>2</SUB>O<SUB>3</SUB> and exhibiting a lead equivalent to 150 kV X-rays of 0.05 mmPb/mm or higher. A stabler glass with high radiation shielding capability can be obtained by realizing a SiO<SUB>2</SUB> content of 70% or below and a total content of SiO<SUB>2</SUB> and B<SUB>2</SUB>O<SUB>3</SUB> of 3 to 70%.</p> |
