Abstract

In order to miniaturize the handheld radioisotope identification device and improve the accuracy of recognition results, the gamma spectrum deconvolution calculation based on cadmium zinc telluride (CdZnTe) detector was investigated in this study. The complete research method mainly included three steps: detector response function (DRF) establishment, detector response matrix (DRM) establishment, and deconvolution calculation analysis. According to the comparison between the reconstructed spectra and the measured spectra, all mean square error (MSE) values were less than 0.1%, which verified that the comprehensive analysis method was accurate and feasible.
