Performance of Cu2O-doped recycled window glass as a thermoluminescence dosimeter

This report presents the development of recycle commercial Thai transparent window glass provided by Guardian Industries Corporation for thermoluminescence dosimeter purpose. The window glass was developed by mixing Na2O to reduce melting point, doping with Cu2O at the appropriate concentration of 0.010 mol% to improve the thermoluminescence characteristics and preparing by using the melt quenching technique. The glass samples were cut into dimension of 6 mm×6 mm×1 mm and exposed to X-ray in dose rang of 0-14 mGy at photon energy of 160 keV. Then, glow curve structure, linearity, lower detection limit, annealing procedure, fading and reproducibility were investigated. The result clearly showed that Cu2O doped window glass has a potential candidate for thermoluminescence dosimeter.
