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.

Abstract: An adhesive having shielding properties can provide a bonded part of a structure with neutron shielding properties. The shield adhesive having neutron shielding properties contains a lithium fluoride powder having lithium fluoride purity of 99% or more. The shield adhesive can be a two-pack curable adhesive and contain an epoxy resin as a main component. This shield adhesive can be a two-liquid curing type adhesive, which may contain an epoxy resin as a main component and may contain a modified silicone resin as a curing agent.

Abstract: A dosimeter container comprising a housing portion and a shield portion that surrounds the housing portion is provided. The housing portion houses a radiation dosage measuring device for measuring a dosage of predetermined radiation other than neutron radiation. The shield portion is composed of a member made of a material that transmits predetermined radiation and shields neutron radiation. The shield portion is a LiF sintered body, in particular, a 6LiF sintered body. Further, the shield portion includes at least two or more shield portion components (a body portion and a lid portion), in which adjacent members can abutt against each other. The housing portion is same size as or larger than the size of the radiation dosage measuring device; and the housing portion extends over the entirety of the components. The dosimeter container is preferably used as a dosage measuring body having a radiation dosage measuring device stored in the housing portion.
