Estimate the lifetime of thermoluminescence traps in general-orders of kinetics model of chilli powder samples by using the R package TGCD

Abstract

The kinetic parameters of thermoluminescene (TL) glow peaks of chilli powder irradiated by gamma rays with the different doses of 0, 4 and 8 kGy (i.e. activation energies (E), order of kinetics (b), trapping and recombination probability coefficients (R) and frequency factors (s)) have been determined and evaluated by glow curve deconvolution (GCD) method using the glow curve data to estimate lifetime of TL traps. The kinetic parameters of TL glow peaks are calculated by modeled first-, second-, generalorders of kinetics (GOK) thanking to the computer by using the R package TGCD. The results obtained as comparing the lifetime values of the three samples showed that the values of the 8 kGy irradiated-samples were the lowest whereas the 4 kGy irradiated-samples’value were greater than the non-irradiated samples’ one time.
