AbstractComposites of styrene–butadiene rubber were prepared with three different types of lead oxide, namely, monolead oxide (PbO), lead dioxide (PbO2), and red lead oxide (Pb3O4). Concentrations of Pb3O4ranging between 17 and 88 wt were utilized, whereas 87 wt was used for PbO and PbO2. The prepared composites were investigated for their gamma radiation shielding properties. Moreover, physical and mechanical properties, and electrical conductivity were measured for both the unirradiated and irradiated composites. The highest value obtained for the linear absorption coefficient was 0.424 cm−1for 88 Pb
