Abstract

The invention relates to a method for detecting photon spectra using at least two semiconductor detectors, at least one of said semiconductor detectors being covered with a metal filter. The aim of the invention is to provide a method enabling the radiation dosage to be detected throughout the relevant energy range in real time. To this end, the integral counting rates of the semiconductor detectors are used as input values for the ANN (artificial neural network) -compatible topology, said topology having been trained for this problem definition, and a photon spectrum is allocated to said input values by said ANN.
