Abstract

In order to establish a startup database of the natural radioactivity in the Republic of Macedonia (area of 25713 km2), the elemental concentrations of K, U and Th in the surface soil were determined using high-resolution gamma spectrometry. A total number of 213 soil samples were colIected during the period 2008-2009 from the entire territory of the country. The K elemental concentrations were found to be normally distributed with arithmetic mean value of 1.87 %, ranging from 0.26 to 4.44 %. The results for U and Th elemental concentrations were found to be 10g-normalIy distributed with geometric mean values 3.08 and 9.29 ppm, and arithmetic means 3.36 (varying from 0.74 to 8.99 ppm) and 10.16 ppm (from 1.6 to 35.77 ppm), respectively. The geometric mean values of the ratios ThIU, KIU and Klfh were found to be: 3.12, 0.61 and 0.20, respectively. The results were compared to the results of the studies from other countries.
