|
|
| This study investigates the photon shielding capabilities of (Pb2O3)x (SnO3)1-x (x = 0, 0.2, 0.4, 0.6, 0.8 and 1 coded as C1, C2, C3, C4, C5 and C6 respectively) for medical radiation application. A numerical model was employed to determine the mass attenuation coefficients (MAC) of the mixture using WinXCOM computer program in the energy range of 0.020 – 20.0 MeV. The MAC values was used to calculate the linear attenuation coefficient (LAC), half-value layer (HVL), tenth value layer (TVL),mean free path (MFP), and effective atomic number (Zeff). The results showed a smooth reduction in MAC value as the energy increases for all the mixtures. The maximum (minimum) MAC values were 17.087 (0.0336), 17.083 (0.0337), 17.074 (0.0339), 17.067 (0.0339), 17.060 (0.0341) and 17.054 (0.0342) cm2/g for C1, C2, C3, C4, C5 and C6 respectively. The maximum Value of LAC was obtained at 0.02 MeV with values was obtained at 0.093, 0.098, 0.111, 0.118, 0.128 and 0.133 cm-1 respectively for C1, C2, C3, C4, C5, and C6 respectively. The LAC value are in the order of C6 > C5 > C4 > C3 > C2 > C1. The HVL, TVL, and MFP show similar pattern and are in the order of C1 > C2 > C3 > C4 > C5 > C6. The results indicates that SnO2 showed the highest attenuation capabilities and declined as the Pb2O3 concentration increases. The study indicates that the attenuation of a shielding material can significantly be enhance by SnO2 doping and can be deployed for medical radiation shielding application. |
