  Purpose: Nuclear radiations have broad applications in our daily life, while unwanted radiations are harmful for man as well as environment. The main objective of this study is to search better shielding material for transportation of radioactive substances, to form a light weight safety dress for workers and defence solutions. Materials and methods: Composite of Styrene-Butadiene Rubber (SBR) containing 20 parts per hundred (phr) Boron Carbide (B4C) was prepared using Two Roll Mill. Thermo-oxidative ageing was performed at Pakistan Institute of Engineering and Applied Sciences (PIEAS) using ageing oven in air at circulation speed of 15 rev/min. Thermal oxidative ageing of samples were carried out at 70°C for 12 days in ageing oven. Gamma ageing of samples were carried out by using Gamma irradiation facility at Pakistan Radiation Services (.. View More»
