Description
KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Den Gegenstand der vorliegenden Erfindung bildet ein Verfahren zur Befestigung radioaktiver Masse auf Faserstoff. Diese Fasern können die Form von Fäden oder Geweben haben und für wissenschaftliche, medizinische und industrielle Zwecke verwendet werden.The subject of the present invention is a method for the attachment of radioactive Mass on fiber. These fibers can take the form of threads or fabrics and used for scientific, medical and industrial purposes.
Nach dem neuen Verfahren werden die radioaktiven Stoffe auf den Fasern befestigt, ohne daß für die Fixierung — wie bisher —According to the new process, the radioactive substances are attached to the fibers, without the need for fixation - as before -
to Firnis, Leim oder irgendein anderes fremdes Bindemittel verwendet wird, wodurch die Ausstrahlungen und die Emanation beeinträchtigt werden.to varnish, glue, or any other foreign binder is used, reducing the radiations and the emanation will be impaired.
Das Verfahren wird in der Weise ausgeübt, daß man einen Faden oder ein Gewebe aus Faserstoff sorgfältig durch bekannte Mittel reinigt und alsdann mit oder ohne künstliche Erwärmung trocknet. Die so vorbereiteten Fasern werden dann in eine geeignete Beize, beispielsweise eine Tanninlösung von 10 Prozent oder eine konzentrierte Alaunlösung gebracht und hierauf von neuem je nach ihrer Art mit oder ohne künstliche Erwärmung getrocknet. The procedure is carried out in such a way that a thread or a fabric is made Carefully clean pulp by known means and then with or without artificial ones Warming dries. The fibers prepared in this way are then put in a suitable stain, for example a tannin solution of 10 percent or a concentrated alum solution and then dried anew, with or without artificial heating, depending on their type.
Man taucht sie hierauf in eine ammoniakalische Lösung von 2 Prozent Ammoniak von 22° Be. oder, wenn die Vorbehandlung mit Alaun erfolgte, in Wasser.They are then immersed in an ammoniacal solution of 2 percent ammonia 22 ° Be. or, if the pretreatment was with alum, in water.
Man läßt sie nunmehr von neuem trocknen und taucht sie dann in eine Lösung eines Radiumsalzes, welche je nach der gewünschten Dosierung titriert ist. Wenn es sich beispielsweise um Catgut handelt, so kann die Lösung 0,000020 g Radiumbromür auf den KubikZentimeter enthalten. Für Seide, Wolle oder Baumwolle kann die Lösung entsprechend stärker gewählt werden.They are now allowed to dry again and then immersed in a solution of a Radium salt, which is titrated according to the desired dosage. If it is, for example In the case of catgut, the solution can be 0.000020 g of radium bromine per cubic centimeter contain. For silk, wool or cotton, the solution can be chosen correspondingly stronger.
Im allgemeinen brauchen die Fasern nicht länger als eine halbe Stunde in dem Bade zu verbleiben. Das Radium wird hierbei auf den Fasern fixiert und es erübrigt nur noch eine Trocknung der Fasern.In general, the fibers do not need more than half an hour in the bath remain. The radium is fixed on the fibers and it is only superfluous a drying of the fibers.
Die Fixierung der radioaktiven Stoffe auf den Fasern in genau bestimmbarer Menge wird zweckmäßig so ausgeführt, daß man nach der oben erwähnten sorgfältigen Reinigung der Fasern, Fäden oder Gewebe dieselben in eine Lösung von Barium - Radiumchromat in Chromsäure eintaucht. Die Stärke dieser Lösung ist abhängig von der in Aussicht genommenen späteren Verwendung der Fasern. Hierauf setzt man tropfenweise eine Lösung von essigsaurem Natron zu, wodurch langsam das Barium-Radiumchromat aus der Lösung ausgefällt wird und sich auf den Fasern niederschlägt, denen es fest anhaftet.The fixation of the radioactive substances on the fibers in a precisely determinable amount is expediently carried out so that after the careful cleaning mentioned above of fibers, threads or tissues in a solution of barium - radium chromate in Chromic acid dips. The strength of this solution depends on the one envisaged later use of the fibers. A solution of acetic acid baking soda is then added drop by drop, which slowly causes it the barium radium chromate is precipitated from the solution and is deposited on the fibers, to which it is firmly attached.
Man kann hierauf das Radiumchromat in Sulfat überführen, indem man die gemäß vorstehender Beschreibung vorbehandelten Fasern in eine Lösung von Schwefelsäure von geeigneter Zusammensetzung eintaucht, die beispielsweise zwischen den Stärken 1: 10 und ι: 100 schwanken kann.You can then convert the radium chromate into sulfate by using the above Description pretreated fibers in a solution of sulfuric acid of suitable Composition dips, for example between the strengths 1: 10 and ι: 100 can fluctuate.
