摘要： A radiation shielding material includes a main body having communication air holes and made of a base member constituting a three-dimensional reticulate skeletal structure, and a metal having radiation shielding capability. The radiation shielding material has moisture permeability through the communication air holes. The base member contains fibers, a foam material, a porous material, or a spongy material. The metal is provided in the form of a film so as to cover the surfaces of the base member of the main body. The radiation shielding material has a degree of moisture permeability of 1 g/m 2 h or higher measured through the A-2 method that is a water method in accordance with JIS L 1099 where the temperature is modified to 20°C and the humidity is modified to 65% RH.
