    Opis:
    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.

    Opis:
    According to developing technology and conditions of modern life, use of radiation is rapidly increased. Unwittingly, our organs and tissues are exposed to radiation continuously. In order to avoid exposure to this radiation, some studies were carried out on protective clothing. In this study, radiation keeping properties of the fabrics coated with barite are examined. Radiation keeping properties were also determined by the method of image processing. After the experiments, it is determined that barite-coated fabrics absorb radiation better than normal fabrics.

    Opis:
    Developments in nuclear technology in the last century have lead to the use of radiation in different areas of human activity. These are not just the energetics but also food, agriculture, medicine, industry and science. Thus, radiation has become an inevitable phenomenon in our lives. Since we cannot isolate radiation from our life, the radiation protection methods should be available. As alternatives to conventional radiation prevention methods, such as lead and heavy concrete shielding, more functional materials need to become the focus of research. The development of the least harmful to the environment, easily applicable, flexible radiation shields has become very important. In this study, silicon matrix composite panels, doped with different ratios of barite and boron carbide, were produced and characterized by optical and scanning electron microscopy (SEM). Gamma and neutron radiation shielding properties of these materials were investigated. The results have been compared with the lead as the standard shielding material.
