Abstract

Thermoluminescence (TL) properties of new synthetic borosilicate glass (SiO2-H3BO3-Na2CO3) doped with various concentrations of ZnO are studied. The glasses were prepared by the melt quenching method and irradiated with gamma doses in the range of 0.5–500Gy. Some properties such as, dose response, minimum detectable dose, reproducibility of the response, thermal and optical fading and IR absorption were studied. Optimum glass composition with a good linear TL gamma dose response over a wide dose range, as well as low fading and excellent reproducibility is obtained. These appealing features indicated that; this new synthetic TL glass material is useful in many radiation detection applications.
