Annotation: This work presents the results of model research parameters of the radiometric measuring canal with a scintillation detection device. A detector is covered by feedback to stabilize its transmission coefficient at the peak of full absorption. It is shown that the inclusion stabilization circuit integral type in feedback of radiometric tract leads to distortion of the useful signal due to the parametric nature of the feedback. It was found that through the choice of the threshold discriminator in a feedback loop at various points of the reference peak, it is possible to reduce an error of these systems more than in 3-5 times due to the manifestation of the parametric nature of the feedback.
