Gamma Attenuation Properties of SrTiO3 Doped with Rb and Y

Abstract

In this study, an experimental and theoretical study was carried out to investigate the radiation shielding properties of Strontium Titanate (SrTiO3) perovskite ceramic with 1% Rb and Y added. For this purpose, nanocrystal samples of SrTiO3: Rb and Y were synthesized by solid state reaction method. The gamma attenuation properties of Rb and Y doped SrTiO3 were investigated by using narrow beam geometry gamma spectrometry system. In this study, linear and mass attenuation coefficients were determined for 0.1218 MeV, 0.2447, 0.3443, 0.7789, 0.964 and 1.408 MeV energy peaks of Eu-152 and from these values, atomic and electronic cross sections, half value thickness (HVL), tenth value thickness (TVL) and mean free path (MFP) values were also calculated. The results were compared with WinXCom values. It was found that Rb and Y doping increased the attenuation coefficients in the low energy region, but its effects were limited at higher photon energies. The same trend was observed for other calculated parameters such as HVL, TVL and MFP. It was found that SrTiO3 perovskite samples with 1% Rb and Y doping had high attenuation properties and had good potential for shielding and other dosimetric uses. In this study, effective atomic number (Zeff) and effective electron density (Neff), which are important parameters in gamma absorption, were also calculated and compared with experimental results.
