| Abstract | ||
| In the present work some rocks were collected from Makkah, Saudi Arabia. Thermoluminescence technique utilized to investigate the ability of the sample to use as an accidental radiation dosimetry. After γ-ray irradiation by Co-60 source, Makkah rocks sample revealed a peak at 155°C. The peak position is decreased with the increase of the γ-dose. Chemical analysis of Makkah rocks were achieved by using XRF technique. The natural fading, the effect of temperature on the ability of the sample to store the TL-signal and the optimum grain size of the sample were studied. The activation energy was calculated by using peak shape method. The TL-signal exhibits a linear response through the gamma dose range 10Gy-10KGy. In this range of exposure the sample under study can be considered as an accidental dosimetry. The natural fading, the effect of temperature on the ability of the sample to store the TL-signal and the optimum grain size of the sample were studied. The activation energy was calculated by using peak shape method. | ||
