Thermal Fading Rates in LiF:Mg,Ti Main Thermoluminescence Peaks
Abstract
Thermal fading (TF) is important in choosing appropriate thermoluminescence (TL) materials for particular applications. TF is the process of reducing the capability of producing the response due to radiation exposure. The fading rate of LiF based thermoluminescent (TL) material depends on many experimental parameters such as storage temperature, readout mechanism, annealing and radiation type or time based on the storage time before or after radiation.
The general aim of the present work is to investigate if the activation energy E, frequency factor s, temperature T and concentration µ0 values evaluated from the experimental thermal fading rates glow–curves through a computerized glow–curve deconvolution analysis (CGCD), can simulate the thermal fading glow-curves using a phenomenological model for LiF;Mg,Ti.
