Effect of Zinc Oxide Percent on Transmission Properties for (X-Ray) of Rubber Compound (SBR)

Abstract

X-ray beams are comprised of photons of many different energies, and as such are polyenergetic. A characteristic of an x-ray beam that affects the rate of attenuation, and hence the exit intensity of the beam, is its effective energy. Effective energy of the x-ray beam can be considered as the weighted mean of the x-ray photon energies within the beam .

Radiation shielding garments are commonly used in hospitals, clinics and dental offices to protect medical patients and workers from unintentional direct and secondary radiation exposure during diagnostic imaging. To Decrease the Exposure of  Ionizing Radiation in this research discuses this problem. The use of  composite materials is an effective methods for altering the performance of Polymer in engineering plastics , rubber, and fiber materials. Composite materials are used for many reasons Such as lowering cost the Industrial ,Shielding Protection, In this study, 8 different rubber compound were prepared by using (SBR) with Zinc Oxide  ( ZnO ) at different ratio (10,30,40,50,60,70,80 and 100) pphr and constant ratio of Titaniom Dioxide (TiO₂) at 60 pphr. The physical properties such as Tensile ,Elongation , Young Modulus ,Compression and (X-ray) Transmission  were Studied.

Key words:  X-ray beam ,effective energy, ZnO, SBR, Radiation.
