Abstract
Thermoluminescence (TL) kinetics and dosimetry features of newly produced LiF doped with Mg and Ce were
investigated. Different contents of Mg (0–1 mol%) and Ce (0–2 mol%) were introduced in host material by melting
method. The most TL sensitivity of the fabricated phosphor was obtained at 0.7 and 0.05 mol% concentrations of
Mg and Ce impurities, respectively. The optimum pre-irradiation annealing regime of the synthesized LiF-based
material was found at 350 ◦C for 10 min. Kinetic parameters of LiF:Mg,Ce dosimeter were obtained using different
methods of computerized glow curve deconvolution (CGCD), initial rise (IR) and isothermal decay (ID). A good
conformity are observed between the results obtained from different kinetic analysis methods. Other TL features
such as fading, dose response and reusability were also examined
