Assessment of X-Ray Attenuation Coefficients for Some Materials

Abstract

This work focuses on Study of linear and mass attenuation coefficient for radiation safety. Present study is intended to investigate the attenuation coefficient for the various materials of different thickness as absorbers for x-ray source and establish the relations among linear attenuation coefficient, mass attenuation coefficient. Glass, wood, plastic and cork materials are used as absorber. The materials were cut with different thicknesses, Then each material was studied separately by placing the specific Thickness inside the x-ray machine and reading the intensity of the x-rays transmitted from the Thickness in question, then increasing the thickness and reading the intensity. The results showed that the linear attenuation coefficient for glass, wood, plastic and cork is 0.6814, 0.3044, 0.04625, and 0.00614 respectively, and the mass attenuation coefficient for them is 0.000272, 0.000435, 0.0000492 and 0.0000256 respectively. By comparing the results of previous studies on this topic, we find that there is a variation in the results, as a result of the difference in the intensity of rays in terms of voltage and current, or a difference in the thickness of the materials used. This show the glass is better absorber of materials were used in the study. This means that the glass is the best in shielding systems from X-rays.
