In this paper, the simulation of the thermal cleaning procedure in LiF:Mg,[Formula: see text]Ti as well as the investigation of the origin of its glow-peaks have been performed by six electron trapping levels and one recombination center phenomenological model. The most generally accepted parameter of the glow-peaks 1 to 5 of LiF:Mg,[Formula: see text]Ti is their first-order kinetics; this was particularly investigated by the use of the random variation of the kinetic parameters method.

Thermal fading (TF) is an important characteristic 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, maximum temperature, Tm and concentration, n 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.
