Test of Gamma Radiation in Synthetic Water Absorbed Rubber

The aim of this research is studying the effect of nuclear spectrum that is found in a new synthetic belt manufacture from rubber composite with water and salt absorbed propriety suitable for medical, regime and sport. Rubber pastes from (Nitrile Butadiene Rubber) NBR, have been prepared laboratory by mixing different proportions. The hardness, time of swelling, mass and volume for pure NBR have been measured then, four mixtures of (PEG-CMC) were added in the form of gels and powders as polymer composites to absorbed water by make porosities inside rubber. This model was examined by sodium iodide detector, in order to determine the proportion of radiation, within installation material, the results were all within the allowable limits globally. It can be dealt with safely.
