Abstract
A method for automatic drift stabilization in radiation measurement with a detector, a pulse amplitude integral of measured radiation being produced as a standard for the radiation energy absorbed by the detector, using control devices connected to the output side of the detector to adjust the amplification of the detector output on the basis of a defined threshold in the detector output pulse energy spectrum in such a manner that the rate of all detector output pulses having a pulse height greater than the threshold is kept constant, and the measurement result is correspondingly corrected thereby, wherein the threshold is located in the vicinity of a peak in the pulse amplitude spectrum that is caused by the energy loss of naturally occurring cosmic radiation or a component thereof in the detector.
