Thermoluminescence dosimetric properties and effective atomic numbers of window glass

This work presents the main thermoluminescence (TL) dosimetric characteristics of commercial Thai transparent window glass. The amorphous structure of window glass was investigated by XRD. The glow curve revealed a peak (T-m) at 235 degrees C. The thermoluminescence response of window glass was studied after irradiation with photons in the absorb dose range of 0-14.05 mGy, which is of interest for the personal protection level of dosimetry. A linear response was obtained after both the first irradiation and the second irradiation. The minimum detectable dose of window glass was 0.15 mGy. The effective atomic number of window glass as a function of photon energy was calculated. The obtained results for the effective atomic number showed that it is very close to that of human biological tissues (Z(eff) = 6.7-8.4 at studied energy). (C) 2014 Elsevier B.V. All rights reserved.
