EFFECT OF CHLOROPHYLL PERCENT ON TRANSMISSION PROPERTIES FOR (X-RAY) OF RUBBER COMPOUND (SBR)

Ionizing radiation is known to be harmful to human health and heredity. The attenuation of radiation can be achieved by either placing the source of radioactivity at a distance from the personnel and objects surrounding it or by constructing a shield effective enough to absorb most of the radiation before it penetrates the matter. Shielding is mostly required against X-rays and gamma rays, which are very penetrating. Various materials which are used for shielding include lead, copper, bismuth, steel, concretes and organic compounds such as oils, paraffins, plastics and rubber. The shields could take different forms like blocks, plates, rods, pellets, clothing etc , 5 different rubber compound were prepared by using (SBR 1502) type of Styrene Butadiene rubber in level and each recipe reinforced with Chlorophyll molecular (Cll) at different ratio (20,40,60,80 and 100) pphr ( part per hundred )and using Titanium Dioxide (TiO ) at constant ratio (60) pphr at all compound. All of compound measure the transmission of (X-Ray).
