Indium oxide and boron-doped indium oxide thin films were produced using the spray pyrolysis method. XRD measurements were made to determine the structural properties of these synthesized films, and it was observed that the films had a cubic structure. Morphological properties were examined, and it was observed that films were generally homogeneous. It has been observed from the Uv–Vis spectrometer measurements that the transmittance rates increase with the boron doping. The mass and linear attenuation coefficients, half-value layer, mean free path and tenth value layer of different percentages for undoped and boron-doped thin films were investigated experimentally. Electron detector and 6 MeV energy electrons were used in irradiation to make these measurements. The experimental results determined that added boron to indium oxide thin films positively contributed to the radiation shielding property. [ABSTRACT FROM AUTHOR]

In this research, different amounts of Ce-doped ZnO thin films were synthesized using the spray pyrolysis method. Structural, morphological and optical properties of these synthesized films were investigated. In XRD analyses, wurtzite (hexagonal) structures were observed in the films. In SEM analysis, there were changes in the surface morphology of the films with doping, and in cross-section measurement, the thickness of the films was measured to be approximately 1.2 μm. In UV–vis spectrometry analysis, it is seen that the effect of Cerium contribution on optical transmittance and band gap positively affects shielding. NaI(Tl) detector and gamma energies of 384, 1173, and 1333 keV have been used to investigate the radiation protection properties of these synthesized films. As a result of these measurements, linear attenuation coefficient (LAC) values have been obtained. Radiation shielding parameters have been calculated with these (LAC) values. The Mass Attenuation Coefficient (MAC), Half Value Layer (HVL), Tenth Value Layer TVL (and) Mean Free Path (MFP) values have been also calculated using this LAC result. According to these results, Ce-doped ZnO films were found to be effective in radiation shielding. • In this article, the effect of cerium doping ratio to ZnO on radiation shielding was examined. • Thin films were produced using the spray pyrolysis technique. • In experiments on radiation shielding properties, 133Ba 384 keV, 60Co 1173 keV and 60Co 1333 keV energy gamma rays were used. • It was determined that the increase in the Cerium rate had a positive effect on radiation shielding. • It was observed that cerium doping affected the energy band gap.

Purpose of this study is to investigate effect of gadolinium (Gd) content of GdxFe2O3(100-x), (x = 0, 5, 10, 20) composite system on structural, thermal, optical and radiation protection of poly (vinyl alchool) PVA based nanocomposite film. In this study, Gd doped Fe 2 O 3 nanopowders (with Gd = 0, 5, 10 and 20) were synthesized by spray pyrolysis method. The characterization of these powders have been obtained by using X-ray diffractometer (XRD), scanning electron microscopy (SEM), and Uv–vis spectrometer. After then, GdxFe 2 O 3 (100-x)/PVA (x = 0, 5, 10, 20) polymer composite systems were prepared by solution casting technique. The structural, thermal and optical properties of obtained polymer composites have been examined. The irradiation properties of 6 MeV energized X-ray via cLINAC to obtain radiation shielding performance of these different percentage (0, 5, 10, and 20%) Gd doped Fe 2 O 3 PVA thin films were also investigated. By using obtained results, the Linear Attenuation Coefficient (LAC), Half Value Layer (HVL), Tenth Value Layer (TVL), Mass Attenuation Coefficient (MAC). Also, theoretically Z eff value have been calculated. According to all obtained results, it has been seen that the different percentages (0, 5, 10, and 20%) Gd doped Fe 2 O 3 PVA thin films can be used as radiation shielding material. • Purpose of this study is to investigate effect of gadolinium (Gd) content of GdxFe2O3(100-x), (x=0, 5, 10, 15, 20) composite system on structural, thermal, optical and radiation shielding of poly (vinyl alchool) PVA based nanocomposite film. • The characterization of these powders have been obtained by using X-ray diffractometer (XRD), scanning electron microscopy (SEM), and Uv–vis spectrometer. • The irradiation properties of 6 MeV energized X-ray via cLINAC to obtain radiation shielding performance. • By using obtained results, the Linear Attenuation Coefficient (LAC), Half Value Layer (HVL), Tenth Value Layer(TVL), Mass Attenuation Coefficient(MAC). • Also, theoretically Zeff values have been calculated.

In recent years, the production of alternative materials instead of lead in the environmentally sensitive and non-toxic material research in radiation shielding has been gained importance. In this study, transparent pristine and boron (B) doped zinc oxide (ZnO) thin films were synthesized by spray pyrolysis method. The crystalline structure, morphology and optical properties of the produced films were investigated with X-ray diffractometer (XRD), scanning electron microcopy (SEM) and Uv–vis spectrometer. The wurtzite structure of pure ZnO was deformed by boron doping found from XRD results. The hexagonal rods have been worsened with boron doping observed from SEM analysis. The factors related to radiation shielding; mass and linear attenuation coefficients, half value layer, mean free path and tenth value layer of different percentage (5, 10 and 20%) B doped ZnO thin films were examined. To perform these measurements, PTW® electron detector and irradiation have been utilized with 6 MeV energized electrons by using VARIAN®. The obtained results from these measurements can be useful to understanding of radiation shielding performance of ZnO:B thin films. • Pristine and boron doped zinc oxide thin films were synthesized by pyrolysis methods. • Optical transmittance of the prepared films were enhanced as a function of boron concentration. • The linear attenuation coefficient increased as the percentage of boron in the thin films increased. • ZnO: B thin films can be used as radiation shielding with different materials in radiation treatment centers.
