Description
Verfahren zum messen aktivischer Strahlenmengen. Die Erfindung betrifft ein Verfahren, -%velches zum Messen aktivischer Strahlenmengen dient. Das Verfahren besteht darin, daß eine Schicht Silbernitrat oder Silbernitrit den zu messenden aktivischen Strahlen ausgesetzt wird. Hierdurch tritt, wie bekannt, allmählich eine gleichmäßige, mehr oder weniger kräftige Bräunung ein, welche als Maßstab für die Messung dient. Die Bräunung nimmt proportional mit der auf- oder durchfallenden Lichtmenge zu, und umgekehrt-wird bei Anwendung gleicher Silbernitrat- oder Silbern 'tritschichten durch gleiche Lichtmengen gleiche Bräunung erzielt, so daß auch auf diese Weise Vergleiche gezogen und Messungen vorgenommen werden können.Method for measuring active amounts of radiation. The invention relates to a method -% velches is used to measure active amounts of radiation. The procedure is that a layer of silver nitrate or silver nitrite is the one to be measured is exposed to active rays. As is well known, this gradually causes a even, more or less vigorous browning, which serves as a benchmark for the Measurement is used. The tan increases proportionally with the amount of color that is noticeable or noticeable The amount of light increases, and vice versa, when the same silver nitrate or silver is used 'Tritschichten achieved the same tan by the same amount of light, so that on in this way comparisons can be drawn and measurements can be made.
Ein besonderer Vorteil dieser Substanzen für die Messung besteht darin, daß sie im Gegensatz zu den sonst verwendeten festen Silberderivaten (Silberhaloiden) löslich sind. Dadurch wird erreicht, daß die Veränderung der Schicht durch das Licht weit gleichmäßiger wird als bei den festen Silberderivaten, und damit auch die Messung genauer und leichter durchzuführen.A particular advantage of these substances for the measurement is that that in contrast to the otherwise used solid silver derivatives (silver haloids) are soluble. Thereby it is achieved that the change of the layer by the light is far more uniform than with the solid silver derivatives, and thus also the measurement more accurate and easier to perform.
Das Verfahren wird im Prinzip derart ausgeführt, daß man gleichmäßige Schichten von Silbernitrat- oder Silbernitritgelatine auf irgendeiner Unterlage, wie Glaspapier, Kollodium usw., eintrocknen läßt. Je nach der Wahl der Unterlage kann dann die Färbung in auffallendem oder durchfallendem Licht betrachtet werden.In principle, the method is carried out in such a way that uniform Layers of silver nitrate or silver nitrite gelatin on any surface, such as glass paper, collodion, etc., to dry up. Depending on the choice of pad the color can then be viewed in incident or transmitted light.
Die Herstellung der Schichten geht z. B. in folgender Weise vor sich.The production of the layers goes, for. B. in the following way.
0,z70 g Silbernitrat werden in einer ioprozentigen Gelatinelösung gelöst und in einer Menge von 1o ccm für i qdm auf einer Glasplatte zur Trockne gebracht. Die Platte wird dann so lange belichtet, bis ein bestimmter, als Normalfärbung gewählter Farbton erreicht ist. Die zur Erzeugung dieses Farbtons notwendige Lichtmenge wird als Einheitsmenge den Messungen zugrunde gelegt.0, z70 g of silver nitrate are in a 10% gelatin solution dissolved and in an amount of 10 ccm for 1 qdm on a glass plate to dryness brought. The plate is then exposed to light until a certain color is considered normal selected color is achieved. The amount of light needed to produce this hue is taken as the basis of the measurements as a unit quantity.
