 Kammein und damit der Härte der   Röntgenstrahlen   entspricht. 



   Zur Vornahme einer Dosismessung wird die Bleiplatte d eingesetzt. Es dirt dann nur die dmch die Platten q und r eingeschlossene Kammer zur Messung. Durch vorübergehendes Schliessen eines   Druckknopfes t wnd   dem   Electrometer   eine   Ladung erteilt. Infolge   der Ionisierung der in der Kammer eingeschlossenen Luft findet eine allmähliche Entladung des Elektrometers statt.

 EMI2.1
 Kammein and thus corresponds to the hardness of the X-rays.



   The lead plate d is used to take a dose measurement. Then only the chamber enclosed by plates q and r is used for measurement. The electrometer is charged by temporarily closing a push button. As a result of the ionization of the air trapped in the chamber, a gradual discharge of the electrometer takes place.
 EMI2.2
   decreases, denotes the amount of total radiation.

PATENT-ANSPRUCH M : essgelät. zur Bestimmung der Härte und Dosis von Röntgenstrahlen, dadurch gekennzeichnet, dass in der Bestrahlungskapsel nebeneinander in Richtung der Röntgenstrahlen zwei lonisierungskammern angeordnet sind, deren eine für die Verwendung des Messgerätes ala Härtemesser mit einer Platte aus Röntgenstrahlen in gewissem Masse absorbierendem, aber wenig Sekundär- stjahlen aussendendem Stoff abgedeckt ist und für die Zwecke der Dosismessung dmch eine Platte aus für Röntgenstrahlen undurchlässigem Stoff gänzlich abgeschlossen werden kann. PATENT CLAIM M: Essgelät. for determining the hardness and dose of X-rays, characterized in that two ionization chambers are arranged next to each other in the direction of the X-rays in the irradiation capsule, one of which for the use of the measuring device as a hardness meter with a plate of X-rays absorbs to a certain extent, but little secondary steel emitting substance is covered and for the purpose of dose measurement dmch a plate made of X-ray opaque substance can be completely closed.
