Abstract

The purpose of the current work is to investigate the effect of the scatter data and the background noise level on the uncertainty of the thermoluminescence (TL) measurements. The Monte-Carlo (MC) algorithm has been used to simulate the scattering data and the background noise signal in TL glow-curve. Under the simulation and experimental parameters used in the present study, a new general criterion for the minimum measurable dose has been established. It has been found from the results that the TL measurements, using either the peak maximum or the peak integral, can be conducted with an uncertainty level $<\pm 10\%[2\sigma ]$ when the TL signal is at least 10 times greater than the background noise signal. It has also been found that the same criterion can be used for the evaluation of the kinetics parameters of the TL glow-peak using either the peak fitting or the peak shape methods.

低剂量水平的热发光不确定度：蒙特卡罗模拟研究

摘要

当前工作的目的是研究散射数据和背景噪声水平对热发光（TL）测量不确定度的影响。蒙特卡洛（MC）算法已用于模拟TL辉光曲线中的散射数据和背景噪声信号。在本研究中使用的模拟和实验参数下，已建立了最小可测剂量的新通用标准。从结果中发现，当TL信号至少为10时，可以使用不确定度$ <\ pm 10 \％[2 \ sigma] $使用峰值最大值或峰值积分进行TL测量。倍于背景噪声信号。
