PROBLEM TO BE SOLVED: To provide a radiation shield structure which is more excellent in radiation shield performance.SOLUTION: A radiation shield structure is configured so that, sheet-state materials having an insulation property are arranged in a longitudinal direction with an angle, for securing a radiation passage distance in each material, to a radiation which enters from a front face, and when the materials are arranged, a radiation which enters from an oblique direction passes plural material cross sections, thereby radiations from all directions to the faces of the materials are attenuated.SELECTED DRAWING: Figure 1 |
