Man is permanently exposed to ionizing radiation due to the presence of naturally occurring radioactive materials (NORM) in the environment. Various technological processes for the processing and use of materials containing natural radionuclides yield materials of increased natural radioactivity (TENORM). The largest contribution to irradiation with natural sources of ionizing radiation is the exposure of the population to radon indoors, which originates from the disintegration of 226Ra and 224Ra contained in the soil beneath the buildings and building materials. Depending on the type of building materials, exposure to radon in indoor work and living spaces can be over a thousand times greater than in open space. No valid and comprehensive radiological investigations of building materials have been performed in Bosnia and Herzegovina, which would guarantee their safety and dosimetric accuracy for installation in residential and industrial buildings, highways, as well as their application for other purposes. The quantification of radon levels, which comes from building materials, is a necessary and very important segment of global protection for the protection of the population from ionizing radiation. This paper presents the first results of a study of the radon activity concentration in building materials used in Bosnia and Herzegovina. Measurements were made using a professional Alpha GUARD system. The mean values of the activity concentration of the exhaled radon of exploratory building materials varied from 10 Bq/m3 to 101 Bq/m3.
