Analyzing the dose response curves for lithium fluoride powder (LiF) in different mesh size induced by Gamma beam for using in thermoluminescence dosimetry

The effect of the different parameters on the thermoluminescence behavior of LiF:Mg,Ti powder produced by melting method is reported. Standard powder of LiF:Mg,Ti manufactured by Harshaw company, was converted to smaller grains size, to obtain different meshes after melting and cooling steps. Powder in this study are of mesh size: 80 to 100, 120 to 140 and 170 to 200 µm. The results show that the melting process affect the glow curve shape, fading factor and repeatability factor of the produced phosphor.
