[en] The specific activity, radiation hazard index and the annual effective dose of the naturally occurring radioactive elements ("2"3"8U, "2"3"2Th and "4"0K) were determined in soil samples collected from 12 different locations in Ayranci region by using a NaI(Tl) gamma-ray spectrometer. The measured activity concentrations of the natural radionuclides in studied soil samples were compared with the corresponding results of different countries and the internationally reported values. From the analysis, it is found that these materials may be safely used as construction materials and do not pose significant radiation hazards. (paper)
