The analysis of γ -ray spectra can be an arduous task, especially in the case of room temperature semiconductor detectors, where several distortions and instrumental artifacts conceal the true spectral shape. We developed a genetic algorithm to perform the unfolding of γ -spectra in order to restore the true energy distribution of the incoming radiation. We successfully validated our approach on experimental spectra of four radionuclides ( 241 Am, 57 Co, 137 Cs and 133 Ba) acquired with two CdZnTe -based detectors with different contact geometries (single pixel and drift strip). The unfolded spectra consist of δ -like peaks in correspondence with the radiation emissions of each radioisotope. [ABSTRACT FROM AUTHOR]
