Abstract

STR 5L natural rubber mixed with various amounts of waste ferrite and carbon black (CB) powder
were investigated for shielding efficiency with varying thickness of 1-5 mm. The composites were studied for
gamma ray shielding by using 241 Am (E = 59.8 keV) as a gamma radiation source. It was found that the
shielding efficiency increased with increasing amount of ferrite and specimen thickness. The attenuation
coefficient is 2.31 cm-1 for 100 phr of ferrite and 20 phr of carbon black in the rubber composite. Tensile
strength, hardness and density of these composites were also investigated
