Ionizing radiation shielding features for titanium borosilicate glass modified with different concentrations of barium oxide

Photon, proton, neutron and alpha shielding features of 10TiO2-10SiO2-(80-x)B2O3-xBaO were studied. This study exhibits several photon shielding parameters such as mass attenuation coefficient (MAC), half-value layer (HVL), effective atomic number (Zeff), effective electron density (Neff), gamma dose rate (R/h), specific gammaray constant (Gamma), and the specific absorbed fraction of the energy (SAFE). The effective removal cross-section of the fast neutron (sigma R), scattering length of the constituent elements, mass stopping power (MSP), and projected range variation parameters were used to explore the particle shielding features. Moreover, the MAC was determined by using Geant4 simulation and compared with the results of the Phy-X program. The percentage error (Delta) was less than 2% for all results, which revealed the agreement between Geant4 simulation and Phy-X program. Although, the addendum of barium oxide (BaO) led to improving the performance of MAC, HVL, Zeff, Neff, and Gamma. The sigma R, MSP and projected range variation showed a progressive reduction with incorporation BaO. Lastly, the BaO and SiO2 played an amazing role in enhancement the durability for the glass sample, and the S4 sample exhibits the highest durability compared with other samples. From the obtained results, it can be concluded that the present glass samples can be used in the radiation-shielding field.

Automated summary

The shielding features of 10TiO2-10SiO2-(80-x)B2O3-xBaO were studied, with the addition of barium oxide enhancing the performance of various shielding parameters while reducing the effectiveness removal cross-section of fast neutrons, mass stopping power, and projected range variation.
