Abstract
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/m2 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.

A radiation shielding material for shielding radiation, the radiation shielding material comprising:
- a main body having communication air holes, the main body being made of a base member constituting a three-dimensional reticulate skeletal structure;
- and
- a metal having radiation shielding capability, wherein the radiation shielding material has moisture permeability through the communication air holes, wherein the metal is applied to the base member by the steps of:
- roughening surfaces of the base member;
- allowing a catalyst to be absorbed by the roughened surfaces of the base member;
- and,
- forming layers of the metal on the surfaces of the base member using a plating process.
