The Analysis of Main Dosimetric Glow Peaks in CaF₂:Tm (TLD-300)

The thermoluminescence properties of CaF₂:Tm (TLD-300) are examined in detail after β-irradiation at room temperature. The glow curve of the sample shows two main dosimetric glow peaks: P3 (at ～150°C) and P5 (at ～250°C). The additive dose, variable heating rate, computer glow curve deconvolution, peak shape and three points methods are used to evaluate the trapping parameters, namely the order of kinetics (b), activation energy (E) and frequency factor (s) associated with the dosimetric thermoluminescent glow peaks (P3 and P5) of CaF₂:Tm (TLD-300) after different dose levels with β-irradiation.
