A Study of the Effects of Radiation on Barium Carb 3) Treated with Gum Arabic in onate (Baco Different Time Periods

Abstract

Gamma rays interaction with matter is important from the perspective of shielding against their effect on biological matter.They are considered as ionizing radiation whose scattered by electrons and nuclei leads to the creation of a radiation field containing negative electrons and positive ions.The main modes of interaction of gamma rays with matter are the photo effect both in its photoelectric and photonuclear forms, Compton scattering and electron positron pair production. Aim of the research was the effect of gamma rays on matter, Study of optical properties of 0.01gram gum Sudan and Study the behaviors of composite Nanomaterial when gamma rays exposure. In this research dealt with a scientific study to Been studying the effect of radiation on a substance Baco3 0.01gram gum Sudan in different periods of time, and the results were clear on the material in the absorption and excitation processes, as well as the absorption and excitation coefficients, and the results indicated that the more time the effect of radiation on the material increased, the absorption process was The material and its excitation are weak and equally the absorption and excitation coefficients. On the other hand, the results of the energy gaps indicate that the longer the time of the effect of radiation on the material, the greater the energy gaps in the excited material. The effect of rays is greater, and the shorter the period of exposure, the less the effect of radiation on the materi
