Using the computerized glow curve deconvolution method and the R package tgcd to determination of thermoluminescence kinetic parameters of chilli powder samples by GOK model and OTOR one

Determine dose-saturation level from thermoluminescence curves by the GOK and OTOR models

“…Both saturated and unsaturated samples were simulated and computed basing the R package tgcd [4,9]. The simulated samples include the saturated samples with a spectral peak (TL1), the unsaturated samples with a spectral peak (TL2), the saturated samples with two spectral peaks (TL3) and the unsaturated samples with two spectral peaks (TL4).…”

“…In addition, the two TL curves of the chilli powder sample irradiated at a dose of 8 kGy and preserved 360 h and 720 h after being irradiated were used to determine saturation. TL curves of the chilli samples fitted to both the GOK and OTOR models are mentioned [4]. The chilli powder samples irradiated with a dose of 8 kGy were tested for their saturation.…”

“…When the figure of merit of two models is relatively small that allows us to compute the dynamic parameters of the TL spectrum by GOK and OTOR models. The kinetic parameters of TL glow peaks of chilli powder irradiated by gamma rays with the different doses of 0, 4 and 8 kGy have been calculated and estimate by computerized glow curve deconvolution method and the R package tgcd by using the TL glow curve data [4]. From these parameters, calculating the saturation ratio between the initial number of trapped electrons (n 0 ) and the total concentration of trapping states (N) are presented.…”

“…This empirical TL curve is the overlap of many complicated TL peaks that were conducted to separate peaks each other and determine the saturation values of each peak based on this study results. In addition, the TL curves of irradiated pepper samples with 8 kGy dose with 360 and 720 h [4] after irradiation were also included to determine dose-saturation level.…”

Nghiên cứu XỬ LÍ phổ NHIỆT PHÁT QUANG (TL) BẰNG PHẦN MỀM PYTHON

“…Việc khảo sát tổng quan và ứng dụng phương pháp TL trong thực phẩm chiếu xạ với mẫu là bột ớt đã được nghiên cứu (Nguyen, 2015). Nhằm xác định các thành phần, cấu trúc của vật liệu đã có một số nghiên cứu liên quan đến các thông số động học của bẫy TL của phổ TL (Peng, Dong, & Han, 2016;Nguyen, 2017;Nguyen, Tran, Nguyen & Nguyen, 2017. Một số nghiên cứu khác liên quan đến hiệu ứng fading của phổ TL (sự suy giảm tín hiệu TL theo thời gian) có sử dụng máy học và phần mềm Python (Amit & Datz, 2018;Kröninger, Mentzel, Theinert, & Walbersloh, 2019;Theinert et al, 2018).…”
