  Investigation of the radiation shielding capability of xPbO – (50 - x) BaO – 50 B 2O 3 glass system using Geant4, Fluka, WinXCOM and comparison of data with the experimental data

  Aşkin, A.; Mutuwong, C.; Nutaro, T.; Dal, M.

  In this study, mass attenuation coefficient (μm), transmission fractions (T), effective atomic numbers (Z eff) and half-value layer (HVL) of the xPbO –(50 - x) BaO –50 B 2O 3 (where x=10,20,30,40mol%) glass system have been determined from the Monte Carlo simulations carried out with Geant4 and Fluka simulation toolkits and WinXCOM database software. The calculated results were compared with the experimentally obtained μm values of the selected glass in order to validate the Geant4 model of HPGe detector and Fluka model of NaI(Tl) detectors. T, Z eff and HVL shielding parameters of the studied glass system indicate that increase of PbO content from 10 to 40% results in a better shielding behaviour thanks to the high atomic number of lead.

  Evaluation of the gamma and neutron shielding properties of 64 TeO 2+ 15 ZnO + (20 - x) CdO + xBaO + 1 V 2O 5 glass system using Geant4 simulation and Phy-X database software

  Aşkin, A.

  In this study, fast neutron removal cross-section and γ-ray shielding capabilities in terms of mass attenuation coefficient (μm), transmission fractions (T), effective atomic numbers (Zeff), half-value layer (HVL) and exposure build-up factors (EBF) of the 64 TeO 2+ 15 ZnO + (20 - x) CdO + xBaO + 1 V 2O 5 (x= 0 , 5 , 10 , 15 , 20 mol%) glass system have been evaluated using Monte Carlo simulations carried out with Geant4 model of the high-purity germanium (HPGe) detector and Phy-X database software. The results of this study revealed that γ-ray shielding capability of the studied glass system increases with the increase of BaO content and decrease of CdO content in the chemical structure due to the high atomic number (Z) of Ba compared to Cd. The results also showed that increase of BaO fraction in the glass structure weakens the neutron shielding ability and by the use of low Z elements in the composites better shielding performance against neutrons can be obtained.
