Zur Behandlung von radioaktiv strahlendem Material werden Handschuhboxen eingesetzt. Hierbei handelt es sich um allseits geschlossene Behälter, in denen mit eingesetzten Handschuhen versehene Öffnungen angebracht sind. Diese Handschuhe sind also mit dem Behälter fest verbunden und gestatten es, daß von außen im Behälterinneren Arbeiten vorgenommen werden können, ohne daß die Atmosphäre des Behälterinneren mit der Atmosphäre außerhalb des Behälters in Berührung kommt.Glove boxes are used to treat radioactive material. This is all about closed containers with openings provided with gloves in place. So these gloves are firmly connected to the container and allow that work can be carried out from the outside inside the container without the atmosphere inside the container comes into contact with the atmosphere outside the container.
Manche radioaktiven Materialien senden eine Neutronenstrahlung aus, die die zulässige Arbeitszeit an einer Handschuhbox durch die für das Personal auftretende Strahlenbelastung zeitlich sehr reduziert.Some radioactive materials emit neutron radiation that takes the permissible working time through a glove box the radiation exposure that occurs for the staff is greatly reduced in terms of time.
Aufgabe der neuen Anordnung ist es, eine Neutronenabschirmung zu schaffen, die mindestens teilweise auch während des Arbeitens innerhalb der Handschuhbox wirksam ist und trotzdem die Arbeiten innerhalb der Handschuhbox nicht wesentlich erschwert.The task of the new arrangement is to create a neutron shield, which is at least partially also during work is effective within the glove box and nevertheless does not make work within the glove box significantly more difficult.
Die Neuerung betrifft damit eine Neutronenabschirmung für eine Handschuhbox, in der sich spaltbares Material befindet, unter Verwendung einer borhaltigen Glasschicht.The innovation thus relates to a neutron shield for a glove box in which there is fissile material, underneath Use of a boron-containing glass layer.
Das Neue besteht dabei darin, daß die Abschirmung aus mehreren an einem Rahmen befestigten Türsegmenten besteht und daß als Türsegmente Platten aus miteinander verklebten Acrylglasschichten mit einer auf die äußere Schicht aufgeklebten borhaltigenThe novelty is that the shield consists of several door segments attached to a frame and that as Door segments Panels made of acrylic glass layers glued together with a boron-containing layer glued to the outer layer

Ein Ausführungsbeispiel ist in Figur 1 in einer Seitenansicht und in Figur 2 in einer Aufsicht dargestellt.An embodiment is shown in Figure 1 in a side view and in Figure 2 in a plan view.
Die Handschuhbox 1 ist oben mit Deckeln 2 abgeschlossen und weist an ihren Seitenwänden 3 Öffnungen 4 auf, in die Gummischläuche, deren Abschluß eine Handschuhform hat, eingesetzt sind. Zur Abschirmung gegen Neutronenstrahlung ist vor den Seitenwänden ein Rahmen 5 vorgesehen, an dem mehrere Türsegmente 6 befestigt sind. Die Türsegmente 6 sind dabei so angeordnet, daß sich vor jeder Öffnung 4 ein Türsegment befindet. Die einzelnen Türsegmente bestehen aus mehreren Schichten 7, dir aus Acrylglas bestehen und miteinander* verklebt sind. Die äußere Schicht 8 besteht aus einem borhaltigen Glas, die die in den Acrylglasschichten verlangsamten Neutronen auffängt. Werden nun eine oder mehrere Öffnungen benötigt, um Arbeiten innerhalb der Handschuhbox auszuführen, so genügt es, nur die Türsegmente aufzuklappen, die vor den betreffenden öffnungen angebracht sind; Dabei bleibt die in der Handschuhbox arbeitende I-eraori weitgehend durch die übrigen Türsegmente vor Neutronenstrahlung abgeschirmt, so daß die Strahlenbelastung pro Zeiteinheit auf ein Mindestmaß beschränkt ist.The glove box 1 is closed at the top with lids 2 and has 3 openings 4 on its side walls, into which rubber hoses, the end of which has a glove shape are used. To shield against neutron radiation is in front of the Side walls a frame 5 is provided to which several door segments 6 are attached. The door segments 6 are arranged so that that there is a door segment in front of each opening 4. The individual door segments consist of several layers 7, dir consist of acrylic glass and are glued together *. The outer Layer 8 consists of a boron-containing glass that captures the neutrons that are slowed down in the acrylic glass layers. Will now One or more openings are required to carry out work inside the glove box, so it is sufficient to only open the door segments unfold, which are attached in front of the relevant openings; The I-eraori working in the glove box remains largely shielded by the remaining door segments from neutron radiation, so that the radiation exposure per unit of time a minimum is limited.
Die aus Glasschichten bestehende Neutronenabschirmung ist durchsichtig. Dadurch ergibt sich der besondere Vorteil, daß diejenigen vor den in der Handschuhbox angebrachten Glasplatt er/ angeordneten Türsegmente oder Türsegmentteile beim Arbeiten in der Handschuhbox nicht geöffnet werden müssen. Die Öffnung der Abschirmung wird dadurch auf diejenigen Oberflächenteile beschränkt, die dem Zugriff zum Innern der Handschuhbox dienen.The neutron shield, made up of layers of glass, is transparent. This has the particular advantage that those in front of the glass plate / arranged door segments or door segment parts in the glove box when working do not have to be opened in the glove box. The opening of the shield is thereby exposed to those surface parts limited, which are used to access the interior of the glove box.
