The effects of the scattering data that might appear at the low radiation doses and the temperature lag that might occur between the heater pan and the detector on the thermoluminescence (TL) glow-curve have been addressed. The scattering data were mathematically induced in the TL glow curve using the Monte Carlo (MC) algorithm. While the phenomenon of the temperature lag has been simulated, assuming an exponential function. The deconvolution analysis has been carried out by TL expressions based on a presumed kinetics order value in comparison with the general-order kinetics equation. It has been found that even though the glow peak is known to obey the first- or second-order kinetics model, using the general-order kinetics equation in the deconvolution analysis is better than using the corresponding model equation.

散射数据和温度滞后对热发光辉光峰分析的影响:蒙特卡洛模拟研究

已经解决了在低辐射剂量下可能出现的散射数据以及在热锅(TL)辉光曲线上在加热盘和检测器之间可能出现的温度滞后的影响。使用蒙特卡洛(MC)算法在TL辉光曲线中数学得出散射数据。虽然已经模拟了温度滞后现象,但假设是指数函数。与假定的动力学方程相比,TL表达式基于假定的动力学有序值进行了反卷积分析。已经发现,即使已知辉光峰服从一阶或二阶动力学模型,在反卷积分析中使用通用动力学方程也比使用相应的模型方程更好。
