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.

Abstract: A provision device (100) in a provision system providing a user conducting activities through a service with reactions of other users to the user is configured as follows. A presenter (101) presents a current state of the reactions from the other users to the user that have occurred while the user is conducting activities through the service to the user via the service while the user is conducting activities through the service. A notifier (102) gives notice of a summary of the reactions from the other users to the user that have occurred while the user is not conducting activities through the service to the user with no intervention of the service while the user is not conducting activities through the service. Then, as the user conducts a given operation on information contained in the notified summary, the notifier (102) prompts the user to start conducting activities through the service.
