Method and device for monitoring an automated drift compensation

摘要

The method involves applying radiation from a working radiation source (40) with a working radiation source energy spectrum to a scintillator for automatic drift compensation. The radiation is applied from a monitoring radiation source (41) with monitoring the radiation source energy spectrum, which differs from the working radiation source energy spectrum to the scintillator. A counting rate is evaluated by the monitoring radiation source for the purpose of monitoring the automatic drift compensation. An independent claim is also included for an automatic drift compensation monitoring device.
