Provided is a radiation shielding material having excellent radiation shielding effect, which has fluidity that can be filled and extracted by a pump, exhibits the properties of a plastic body after filling, and has an extremely reduced possibility of occurrence of breathing. To do. A radiation shielding material comprising at least 100.0 parts by weight of water, 6.0 to 20.0 parts by weight of clay mineral powder, and 30.0 to 400.0 parts by weight of barium sulfate powder. . Also, a method for producing a radiation shielding material, comprising at least a step of blending water and clay mineral powder to obtain a suspension, and a step of blending the suspension and barium sulfate powder to obtain a fluid composition. It is. [Selection figure] None |
