Öğe Gamma ray shielding properties of CeO2-added hydroxyapatite composite(Springer, 2022) Almisned, Ghada; Akkurt, İskender; Tekin, Hüseyin Ozan; Erdamar, Işık Yeşim Dicle; Doğan, Serap ÖzhanIt is hard to control radiation especially if it is chargeless such as gamma rays. The radiation shielding is expressed in terms of some radiological parameters such as LAC, HVL, TVL, mfp, Zeff, Neff, and Ceff. In this study, the gamma ray shielding properties of hydroxyapatite (HAp) composites have been obtained and the effect of CeO2 on the shielding properties has also been investigated. © 2022, The Author(s) under exclusive licence to Australian Ceramic Society.Öğe Radiation-shielding properties of titanium dioxide-added composites(ICE Publishing, 2022) Choudhary, Manju D.; Akkurt, İskender; Almisned, Ghada; Tekin, Hüseyin OzanIn radiation protection physics, development of alternative shielding materials to lead and lead-based materials is very popular nowadays, and thus, the present work aims to study the radiation-shielding parameters of a newly developed titanium dioxide (TiO2)-added hydroxyapatite composite material. The gamma-ray-shielding parameters were given in terms of the linear attenuation coefficient, half-value length, effective atomic number (Z eff) and effective electron density (N eff) for four different composites. The variations of these parameters with the titanium dioxide rate were also investigatedÖğe Variation in gamma ray shielding properties of glasses with increasing boron oxide content(De Gruyter Open Ltd, 2022) Almisned, Ghada; Akkurt, İskender; Tekin, Hüseyin OzanThe study of radiation shielding properties for a material is an important part of research in scientific world. It is expressed in terms of the linear linear coefficients (LAC) which can also be used to obtain some other parameters. The gamma shielding properties of glass with addition of boron oxides in different amounts were studied, thereby obtaining linear attenuation coefficients (LAC), mean free path (mfp), Exposure Buildup factor (EBF) which were calculated using Phy-X/PSD code. It was found that increasing boron oxide content of 0, 2, 4, 6, 8 (w %) in glass increased the gamma attenuation coefficients. © 2022 Walter de Gruyter GmbH, Berlin/Boston 2022.
