Abstract:
Although radiation is used for many useful purposes today, it has properties that can cause serious harm to human health. Especially, the harmful effects of radiation come from radioactive sources used for diagnosis and treatment in hospitals. Armoring the environment that is used and preventing its effect from being transferred to the external environment is one of the most frequently used methods. For this purpose, lead plates (0.1-3 mm) and concrete (6-26 cm) are used in hospitals. The new building material to be produced is healthy compared to lead since it will have a thin section compared to concrete, and it will have the characteristics of lightness and workability. Precautions to be taken in concrete against radiation are available in the literature, but the concretes in the proposed solutions are both heavy, prone to cracking, and have low fire resistance. In this study different fine minerals are optimized to minimize pores and X-Ray, gamma, and neutron shielding effectiveness were measured. Different thicknesses 1-5 cm were molded after the preparation of glass fiber-reinforced concrete (GRC) to get an equivalent value of 2 mm lead.
