This paper is related to problems concerning thermoluminescence (TL) dating procedures. In our TL dating laboratory the annual dose rates are determined from the high-resolution gamma spectrometry measurements. For spectral investigations a Canberra spectrometer with the HPGe detector and Marinelli geometry (0.5 l capacity) with a shield is used. The method for spectral analysis of radioactivity is based on the Sampo90 computer program. The results of deconvolution of composite gamma-emission lines with strongly overlapping peaks are presented in detail. The typical peak table of environmental samples, which is used as a reference table in our dating procedure, is shown with the respective gamma-ray intensities. Identification procedure is discussed in the context of the natural nuclide and series activity calculation.
