Abstract

The TL properties of LiF:Mg,Ti (TLD-100) dosimeter in gamma and alpha irradiation were studied. The irradiation of gamma and alpha was done using ⁶⁰Co and ²⁴¹Am, respectively. Thermoluminescence glow curves of TLD-100 were compared in different gamma and alpha irradiations. The isothermal decay and variable heating rate methods were applied in determining of kinetic parameters activation energy, order of kinetics and frequency factor. The kinetics parameters of fifth peak (the main dosimetry peak) this TL material in gamma and alpha irradiation were compared with each other.
