Description

BLEIFREIES RÖNTGENSCHUTZ MATERIAL BESCHREIBUNGLEAD-FREE X-RAY PROTECTION MATERIAL DESCRIPTION

Die vorliegende Erfindung befasst sich mit der Herstellung eines Strahlenschutzmaterials, in dem kein Blei Anwendung zum Schutz vor ionisierender Strahlung findet.The present invention relates to the production of a radiation protection material in which no lead is used for protection against ionizing radiation.

Die vorliegende Erfindung ist dadurch gekennzeichnet, dass chemische Elemente mit einer Ordnungszahl grosser oder gleich 50, mit einem Polyvinylchlorid-Acrylnitrilbudatien-Synthesekautschuk-Gemisch zur Herstellung einer dünnen, hochelastischen, leichten, sehr flexiblen Bahnware dienen. Dieses Material hat gummiartige Eigenschaften mit gutem Rückstellvermögen.The present invention is characterized in that chemical elements with an atomic number greater than or equal to 50 are used with a polyvinyl chloride-acrylonitrile-butadiene synthetic rubber mixture to produce a thin, highly elastic, light, very flexible web material. This material has rubber-like properties with good resilience.

Das Gemisch der chemischen Elemente kann zu ungleichen Teilen aus Bariumfluorid, Wolfram, Wismut, Bariumsulfat, Wolframcarbide, Wolfram- borcarbid, Wolframboride, Wismuttrioxid und Wolframoxiden bestehen.The mixture of chemical elements can consist in unequal parts of barium fluoride, tungsten, bismuth, barium sulfate, tungsten carbides, tungsten boron carbide, tungsten borides, bismuth trioxide and tungsten oxides.

Das hergestellte Material wurde nach der DIN Norm 6845-Teil 1: Prüfung von Strahlenschutzstoffen für Röntgen und Gammastrahlung (Röntgenstrahlung bis 400 KV) durch das Bayerische Landesamt für Arbeitsschutz, Arbeitsmedizin und Sicherheitstechnik / München überprüft und zur Herstellung von Strahlenschutzzubehör bei medizinischer Anwendung von Röntgenstrahlen bis 300 KV freigegeben (DIN-Standard DIN-6813). The material produced was tested according to DIN standard 6845-Part 1: Testing of radiation protection materials for X-rays and gamma radiation (X-rays up to 400 KV) by the Bavarian State Office for Occupational Safety, Occupational Medicine and Safety Technology / Munich and approved for the manufacture of radiation protection accessories for medical use of X-rays up to 300 KV (DIN standard DIN-6813).

Die DIN-Standards 6845 , jetzt IEC-1331-1 (1994), IEC-1331-3 (1997) und DIN 6813, jetzt IEC-61331-3, wurden zwischenzeitlich in Europäische Normen umgewandelt und harmonisiert.The DIN standards 6845, now IEC-1331-1 (1994), IEC-1331-3 (1997) and DIN 6813, now IEC-61331-3, have since been converted into European standards and harmonized.

Gegenüber anderen bekannten bleifreien Materialien ist die vorliegende Erfindung dadurch gekennzeichnet, dass die Strahlungsschwächungswerte bei ansteigender KV-Röhrenspannung nicht abfallen sondern proportional ansteigen, ein Umstand, den andere Materialien nicht, erfüllen.Compared to other known lead-free materials, the present invention is characterized in that the radiation attenuation values do not decrease with increasing KV tube voltage but increase proportionally, a circumstance that other materials do not fulfill.
