(received 15 October 2009 ; accepted 21 October 2009) Abstract. - The radiation shielding properties of glass have been calcu- lated at 1 keV- 1 GeV and compared with the measurement performed using gamma spectrometer connected to NaI(Tl) detector at 662, 1170 and 1332 keV. The possibility of radiation shielding properties of glass has been investigated by coating glass with the TiO 2 . 1. Introduction The glass is widely used material in different purposes such as window and personel glass. For this reason, choosing of glass type or improving of glass properties have became important. Although there are several way to use glass in different format, the coating of the glass is becomes important. TiO 2 (titanium dioxide) has been started to be used in researches very frequently in recent years because of its different chemical, electrical and optical characteristics[1]. TiO 2 occurs in at least seven differ- ent polymorphic forms, four of which are found in nature. Rutile is a crystallization product of igneous rocks, and rutile, anatase, brookite and TiO 2 occurs as accessory minerals in alteration assemblages and sedimentary and metamorphic rocks [2]. As the radiation is part of our life, the radiation shielding properties of glasses is impor- tant and it should be investigated. Several works have been done on the radiation shielding properties of different materials[3,4] including glass[5]. In this work radiation shielding properties of glass and its variation with the coating processes will be discussed.
