A radiation shielding wall is provided to enhance a shielding force of radiation or reduce a thickness of a concrete wall by filling an inside of the concrete wall with a mixture of metal ball and liquid based gap remover and then hardening the mixture. In a concrete structure body, a ground face, a sidewall face, and a ceiling are built with a concrete wall(111) for sealing an inner space thereof and a steel or stainless based door is formed at one side of the concrete wall(111). A radiation shielding wall(100f) is formed by filling the concrete wall(111) and the door with a ball-shape metal ball(120), convenient for a carriage and handling when carrying out a construction work for shielding a radiation. |
