Abstract
A counting tube for detecting radioactive radiation exclusively uses cathode pads for signal detection, which are disposed electrically insulated on the interior of an inner wall of the counting tube housing opposite the sample. A discrete electronic evaluation element is preferably allocated to each cathode element, which makes possible parallel evaluation of the counting tube signal. The cathode pads are in particular laminated in the form of a metal-coated conductive surface on a support plate made of an insulating material. The field of application of such counting tubes with the exclusive use of cathode pads is in particular in connection with multiple counting tubes where the partial areas of a total area to be measured are intended to be individually detected and evaluated.
