Phase and structural investigations of the content of natural radionuclides in rock and inorganic building materials

Abstract

The population living in areas rich in granites, minerals and soils with high concentrations of natural radionuclides is exposed to higher external radiation. Significant part of a person's time resides in buildings where he lives and works. The walls, floors and roofs of the buildings shield (weaken) the external gamma background. The aim of the work is to determine the content of natural radionuclides in rock and inorganic materials used as building materials of samples taken from different buildings in Southern Bulgaria by analysing the samples and measuring their natural radioactivity, then to compare the results with the maximum concentrations of activity in common building materials. also used in the EU. The data obtained from the analyzes do not give grounds to expect the generation of radionuclides from natural and conventional inorganic building materials used in the studied areas.
