Description

In this study the effect of radiation ionization of the 40SrO–30B2O$_{3}$–10TeO$_2$–20Bi$_2$O3, 35SrO–30B$_2$O$_3$–10TeO$_2$–25Bi2O$_3$, 30SrO–30B$_2$O$_3$–10TeO$_2$–30Bi$_2$O$_3$, 25SrO–30B$_2$O$_3$–10TeO$_2$ 35Bi$_2$O$_3$, 20SrO–30B$_2$O$_3$–10TeOS$_2$–40Bi$_2$O$_3$ glass was investigated using the Phy-X/PSD, XCOM simulation Software and ratified using the geant4 simulation. Between the high energy region between 1 MeV and 15 MeV, the mass attenuation coefficients (MAC), linear attenuation coefficient (LAC), and Effective atomic number of all the glasses under investigation were calculated. The results show that increasing the concentration of Bi$_2$O$_3$ in these glasses improves its radiation shielding ability. The half value layer (HVL), tenth value layer (TVL) and mean free path (MFP) of the glass were investigated and the results show that glasses with a high concentration of Bi$_2$O$_3$ attenuated high amount of photons at a smaller thickness. It was also observed 20SrO 30B$_2$O$_3$–10TeOS$_2$–40Bi$_2$O$_3$ glass has better radiation shielding compared to other radiation shielding materials that have been investigated.
