Abstract
A technique has been developed whereby a pre-dose of gamma radiation (1 kGy) followed thermal activation (to 600 C) and the use of fired Egyptian orthoclase leads to a large increase in sensitivity of the first thermoluminescent (TL) peak. The effect of applying this technique followed by various cooling procedures was examined. This procedure can he used for thermoluminescence dating. The sensitivity enhancement rate of the orthoclase was found to be 0,031 per Gy, while the paleodose was 66.08 Gy. The TL response to beta rays of the sensitized orthoclase was Studied over the dose range of 10-10(4) mGy. This indicates the possibility of applying the investigated material to beta-ray dosimetry within this range.
