摘要：
A radiation shielding sheet formed by filling a shielding material into an organic polymer material. The shielding material is an oxide powder containing at least one element selected from the group consisting of lanthanum (La), cerium (Ce), praseodymium (Pr), neodymium (Nd), samarium (Sm), europium (Eu) and gadolinium (Gd). The oxide powder has an average grain size of 1 to 20 μm, and a volumetric ratio of the shielding material filled in the radiation shielding sheet is 40 to 80 vol. %.
