Glow-curve de-convolution analysis of TL glow-curve from constant temperature hot gas TLD readers

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.

► Routine CGCD analysis of TL glow-curves from stable temperature hot gas TL readers.
► Normalization of glow-curves over intensity and temperature is used before analysis.
► Normalization allows CGCD analysis using the same set of initial values of fitting parameters.
► TL glow-curves from TL dose response, TL statistics and abnormal TL glow-curves were de-convolved.
