Investigate various shielding parameters for (C18H20O8)x (ZrSiO4)100-x and (C18H20O8)x (BiClO)100-x in medical radiological applications

Abstract

This study investigates some of shielding parameters of (C18H20O8)x (ZrSiO4)100-x and (C18H20O8)x (BiClO)100-x, x=(95,80,65,50)% wt coded as (S1,S2) for medical radiation application. We employed a theoretical model to calculate a mixture’s mass attenuation coefficients (MAC) during our investigation. The XCOM computer program was utilized for this purpose within the energy range of (0.356,0.364,0.44,0.662,0.739,0.834,0.846,1.17,1.238,1.274,1.33,1.368 and 2.754) MeV. The MAC values were used to compute several parameters, such as the linear attenuation coefficient LAC, half-value layer HVL, and effective atomic number Z eff . The study’s findings revealed a consistent decrease in the value of LAC as the energy increased for all the mixtures. The maximum value of LAC is 0.366 cm−1 in energy 0.356 MeV at x=50 for S2. The results show that adding BiClO to a matrix material can greatly improve its attenuation properties and be used to protect against medical radiation. The results show that the values of Z eff decreased with increasing energies, then stabilized and changed slightly at increasing energy. The lowest HVL values and the best for shielding were in group S2. The investigation also examined the association between the Z eff and the LAC at the value of x=50. The results show the correlation was positive and strong.
