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.
