Description

Einrichtung zur Strahlenabschirmung Die Erfindung betrifft eine Einrichtung zur Strahlenabschirmung unter Verwendung von Strahlenschutzwerkstoff geringer Eigenradioaktivität für Räume mit geringem Strahlungsniveau (low-levelrooms), wie sie bei der Messung minimaler Radioaktivitäten, namentlich des menschlichen Körpers (Whole-Body-Monitoren), benötigt werden.Device for radiation shielding The invention relates to a device for radiation shielding using radiation protection material with low intrinsic radioactivity For rooms with a low level of radiation (low-level rooms), such as those used for measurements minimal radio activity, namely of the human body (whole-body monitors), are needed.

Abschirmeinrichtungen gegen Strahleneinwirkungen der eingangs erwähnten Art sind in einigen Ausführungen bekannt. Zur Herstellung der Bauelemente, die zum Aufbau der bekannten Abschirmeinrichtungen gegen Strahleneinwirkungen dienen, wurden bisher verschiedene Werkstoffe verwendet. Die bisher verwendeten Werkstoffe, insbesondere Stahl, Blei, Quecksilber, Beton und Wasser, entsprechen nicht in allen Fällen, vor allem nicht bei Räumen mit geringem Strahlungsniveau, den geforderten Bedingungen der modernen Meßtechnik.Shielding devices against the effects of radiation mentioned at the beginning Art are known in some designs. To manufacture the components that are used for Construction of the known shielding devices against the effects of radiation are used different materials used so far. The materials used so far, in particular Steel, lead, mercury, concrete and water, do not match in all cases especially not in rooms with a low level of radiation, the required conditions of modern measuring technology.

Der wichtigste Nachteil dieser Werkstoffe besteht dabei in ihrer zu hohen Eigenstrahlung bzw. in den Schwierigkeiten bei der Beschaffung von strahlungsarmem Werkstoff, insbesondere des am häufigsten verwendeten Werkstoffes Stahl, der, wenn er sehr eigenstrahlungsarm sein soll, nur mit hohem Kostenaufwand für Material und Transport zu beschaffen ist, noch dazu, wenn der Bedarf durch Importlieferungen gedeckt werden muß.The main disadvantage of these materials is their too high natural radiation or in the difficulties in obtaining low-radiation Material, especially the most commonly used material steel, which, if it should be very low in intrinsic radiation, only with high costs for material and Transport is to be procured, especially if the need is through import deliveries must be covered.

Aufgabe der Erfindung ist es, die Herstellung von Abschirmeinrichtungen der bezeichneten Art wesentlich vorteilhafter, insbesondere billiger und technologisch einfacher zu gestalten und die geschilderten Mängel zu beseitigen.The object of the invention is to produce shielding devices of the type described, much more advantageous, in particular cheaper and technologically easier to design and to eliminate the deficiencies described.

Erfindungsgemäß wird dieser vorteilhafte Aufbau derartiger Abschirmeinrichtungen dann erreicht, wenn aus Gips hergestellte Bauelemente Verwendung finden. Für Aufbauten mit speziellen Forderungen ist es von weiterem Vorteil, wenn die Gipsbauelemente mit Bewehrungen oder dünnen Schutzmänteln versehen sind.According to the invention, this advantageous structure of such shielding devices becomes achieved when components made of plaster are used. For superstructures with special requirements it is of further advantage if the gypsum building elements are provided with reinforcement or thin protective sheaths.
