Abstract
A box-type structure includes a structure having neutron beam shielding performance. It is possible to accommodate an organism to be irradiated in the structure. The box-type structure includes shielding plates, which include a lithium-fluoride sintered body having neutron shielding performance. Edge portions of the shielding plates are joined by abutting against one another. The edge portions of the shielding plates have a halving joint structure, and the halving joint structure has a stepped or inclined cutout shape. The box-type structure has a plurality of surfaces, and at least one of the faces may be removable or there may be an opening portion in part of the surface.
