The estimation of the radioactivity levels of materials utilized in construction sectors is crucial in the assessment of possible radiological hazards to human health. In the paper, the results of gamma spectroscopy study of 211 zircon, 425 sand, 781 lime, 348 perlite, 2692 cement, 232 calplex, 968 gypsum, 2741 granite and 21 coal fly ash samples gathered from different countries and imported in Serbia in period 2006-2016 were presented. In order to assess the radiological impact from the investigated samples, the activity concentration index I-RP112 for all samples was ascertained. This research yields insight into the radioactive content in a variety of building materials of different origin. The obtained results were discussed on the basis of relevant national and international legislation and guidance and compared with the corresponding results in the literature.
