Abstract

In radiation shielding, health physics, knowing buildup factors of various materials is necessary. This paper attempts to perform some Monte Carlo simulations with the most recent cross section data to calculate the buildup factors associated with flux and energy of several gamma-ray sources (60Co, 137Cs, 192Ir, 75Se and 169Yb) that are commonly employed in industrial radiography by considering radiation shielding materials: Al, concrete, Fe, Sn, Pb, W and U. Linear attenuation coefficient and flux buildup factors were compared with the coefficient measured with a CsI(Tl)-based γ-ray spectrometer for 60Co and 137Cs sources. During this work, the energy buildup factors were fitted based on Berger’s formula and the related coefficients were determined for each radionuclide source-shielding material configuration.
