Barite Effect on Radiation Shielding Properties of Cotton-Polyester Fabric

Since creation of universe there has been radiation around us and this rate is getting higher with the development of technology. Thus radiation shielding becomes important subject for researcher. Besides normal people especially radiation workers in nuclear facilities need extra protection from radiation. This is vital if we think about any kind of nuclear leakage or nuclear attack, fabric becomes very important. For this purpose, cotton-polyester type of fabric has been coated by barite and gamma ray attenuation efficient has been obtained. The fabric was coated in different rate of barite (0%, 40%, 50% and 60%) in order to test effect of barite rate on the fabric. The measurement has been performed for gamma ray energy of 511, 662, and 835 keV using gamma spectrometer system with NaI(Tl) detector. It was found that the attenuation coefficient has increased with the barite coating rate on fabric.
