A Study on the Radiation Shielding and Absorption Effects of Nonwoven Composites by Monte-Carlo Simulation Analysis

The purpose of this study was to investigate the radiation attenuation effect due reflection and refraction that occurs when passes through composite material simulation. gamma-ray shielding ability composites with different structures, such as layered composite, fibrous particle-added composites, compared. For regardless thickness, structure could not be seen. simulated coefficient found than theoretical value, which increased content inorganic materials. Assuming cesium ions absorbed on nonwoven fabric are located in center radioactive absorbent is used an appropriate amount, it expected more 50% gamma rays emitted from can shielded. If have a ability, after adsorbing 137Cs, intensity adsorbed partially attenuated, thereby contributing waste treatment.
