Abstract: Medical institutions with linear accelerators, cyclotrons as installations for particles acceleration, nuclear facilities as nuclear power stations and nuclear research reactors using concrete in building construction. In cost-benefit analysis the question is what are the radiation characteristics of different types of concrete, which could be used to protect against gamma and X rays. In this paper, computer code XCOM was used for the calculation of the total mass attenuation coefficients, which is an important factor for determination of the photon attenuation, as well as during research and testing of radiation protection properties for concrete with components of different type materials. Thereby, the basic absorption radiation characteristics of ordinary and barite concretes, as well as specially selected type of concrete with magnetite and steel and concrete UHPC with barite and nanosilica as specific material composition, were considered. The results of this research point to the conclusion that before the concrete production of certain mechanical properties is approached, it is reasonable to apply the appropriate methodology with the numerical calculation of the basic absorption characteristic of the concrete for protection against gamma and X radiation.
