A radiation shielding article 10 is in the form of a plurality of radiationnshielding glasses 11 that are stuck together with resin films 12 therebetween,nrespectively. Each radiation shielding glass 11 is made of glass essentially freenof Pb and having a lead equivalent of 0.03 mmPb/mm or more relative to an X-raynof 100kV. Further, each radiation shielding glass 11 has a compositionncontaining, by mass%, 50 to 65 % of SiO 2 , 5 to 15 % of Al 2 O 3 , 0.1 to 9 % of ZrO 2 ,n10 to 27 % of MgO+CaO+SrO+BaO+ZnO, and 7 to 15 % of Li 2 O+Na 2 O+K 2 O. |
