A series of lead–natural rubber composites have been produced on a laboratory scale, and their X-ray protection power measured. The effect of antioxidants on the physicomechanical properties and aging characteristics of the composites was investigated. Flex properties and age retention properties showed perceptible improvement upon the addition of antioxidants without changing the X-ray shielding power. An attempt was made to study the morphology of the fractured surfaces of the composites.
