摘要

The present work attempts the generalization of the computerized glow-curves de-convolution (CGCD) analysis of glow-curve received under an exponential heating function (EHF) used in stable temperature hot gas thermoluminescence (TL) readers. The analysis is based on single TL glow-peak analytical expressions derived for the EHF cases. A special normalization procedure is suggested which allows the deconvolution of very different glow-curves using the same set of the initial parameters during the CGCD analysis. More than two hundreds of glow-curves corresponding to TL measurements for dose response, for quality control, for low TL statistics, for background and finally glow-curves with undesired spurious signals. The results show that the CGCD analysis, which is widely used in the case of linear heating, can be used and be equally effective for the case of EHF as well.
