Thermoluminescence Properties of Quartzite Rock after β-irradiation
Journal Title: Cumhuriyet Science journal - Year 2018, Vol 39, Issue 4
Abstract
In the present study, the thermoluminescence characteristics of natural quartzite collected from Karaisalı (Adana) in Turkey were investigated after β irradiation at room temperature with the purpose to use as radiation dosimetry. The glow curve of quartzite mineral shows two peaks at 110 oC and 250 oC and a shoulder at 375 oC, explicitly. The resulting peaks, which were examined using the computer glow curve deconvulation (CGCD) method, were deconvuluted and kinetic parameters (activation energy Ea, frequency factor (s) and kinetic degree (b)) were determined. After CGCD methods, it was seen that the glow curve suporposed at least eight peaks. Additionally, kinetic parameters were determined using by Arrhenius plot obtained from initial rise (IR) method. In this study, it is shown that there is a correspondence between kinetic parameters calculated by IR method and peaks deconvoluated by CGCD technique in low temperature region (P1-P3). Additionally, reusability test was conducted to investigate its usability as a dosimetric material, and a change of 2% was observed in the results of 10 repeated times. Besides to the characterization of this sample X-ray diffraction (XRD) and scanning electron microscopy (SEM) - energy dispersive X-ray (EDX) results were investigated.
