Investigation of dosimetric properties and kinetic parameters of cu and pr doped Sr2P2O7

In this study; the TL dosimetric properties and kinetic parameters of Cu and Pr-doped Sr2P2O7 were investigated. The investigations on pure Sr2P2O7 were indicated that it has one glow peak around 100 0C. On the other hand, it was observed that the Cu and Pr doped Sr2P2O7 has two glow peaks around 100 0C and 200 0C. The detail dosimetric studies of glow peak around 200 0C were shown that this material can be one of the promising TLD material for dosimetric applications, i.e., personal dosimeter. The kinetic parameters of Sr2P2O7:Cu,Pr were analyzed by different methods such as additive dose (AD), TM -TS, repeteated initial rise (RIR), peak shape(PS) and computer glow curve deconvolution (CGCD). The additive dose technique was indicated that the kinetic orders of glow peaks of this sample were described with first-order kinetics. But the other methods were indicated that they have general-order kinetics. The results were shown that there is no good agreement and consensus between the kinetic parameters by various techniques due the variation in the emission spectrum of this sample with temperature, self-absorption and thermal quenching.
