Abstract

The aim of this research is to study the radioactive properties of multicomponent concrete and calculate human radiation doses when it is used in the construction of residential buildings. Research objectives were the experimental determination of the specific activities of natural radionuclides in multicomponent concrete; calculation of the gamma radiation dose from natural radionuclides in concrete and the effective equivalent radiation dose to people living in modern masonry buildings; calculation of the indoor volumetric concentration of radon at its emanation from concrete structures. The specific activities of 226Ra, 232Th and 40K in concrete were determined by using gamma spectrometric analysis. According to the value of the effective specific activity Cef < 370 Bq/kg, the concrete samples can be used in construction without restrictions. The effective equivalent dose of radiation for people living in concrete premises for 50 years is smaller than the public dose limit (1 mSv/year). The calculated effective doses of gamma radiation in premises made of the studied concrete, and the volumetric concentrations of radon isotopes comply with the radiation safety standards, so сoncrete can be used in civil engineering.
