Abstract
A radiation detector circuit, which comprises a radiation detector containing a scintillation crystal and a photomultiplier tube for real time photon measurement having a pulse output, and which also includes a plurality of pulse counters each having a pulse input and a count signal output. Between the pulse output of the photomultiplier tube and the pulse inputs of the pulse counters a time multiplexer is provided for connecting each pulse input of each counter in succeeding time periods with the pulse output of the photomultiplier tube. Furthermore, an evaluation circuit is connected with the count signal outputs of the counters for evaluating each count signal of each counter measured during each of said succeeding time periods in the sense of error estimates and trend analysis.
