Radiation Dose Evaluation of Colorless Topaz by TL and ESR Spectroscopy

Abstract:

In the present work, colorless topaz was designed and developed a dosimeter for routine application. The samples were irradiated with gamma from ⁶⁰Co at dose range 50 - 400 Gy and investigated by thermoluminescence (TL) and electron spin resonance (ESR). The TL grow curve of topaz were revealed two trapping levels at temperature 150 °C and 225 °C. The ESR signals of topaz shown that the g value at 1.966 and 2.012 due to Ti³⁺ and (AlO₄)⁰ center, respectively. The intensities of TL and ESR were increased with increasing dose. The percentage error of dose from TL and ESR signal were 8 and 3, respectively. These experiment indicated that the colorless topaz could be used as a dosimeter.
