Airborne radiometer data is the best to study the distribution of radioactive elements of an area. In this paper, separation of anomaly values have been performed by means of the classical statistics, the tables of frequency distribution of uranium, thorium and potassium have been produced, the frequency distribution histograms that are introducer of distribution and dispersion of these elements have been plotted, and the statistical parameters of these elements have been estimated. The separation of anomaly value has been done based on the dispersion around the average. The distribution maps of radioactive elements were drawn. These mentioned data were controlled in the field by the radiometric measurements and chemical analysis. Finally, the results of radiometric measurements and chemical analysis revealed non-economic mineralization in the region.
