Abstract

To establish baseline values of concentrations of terrestrial radionuclides for the Republic of Macedonia, a survey covering the entire territory was performed. 213 soil samples were collected from regions around the major settlements and cities, about evenly distributed over the geotectonic units which constitute the country’s geological foundation. The specific activities of radionuclides were measured by gamma spectrometry. The values were in ranges: (8-1390) Bq kg-1 for 40K, (9-123) Bq kg-1 for 226Ra, (9-111) Bq kg-1 for 238U and (7-145) Bq kg-1 for 232Th in dry soil. The relation between specific activities of natural radionuclides and geology was investigated. Correlation between radionuclides, which may serve as additional geochemical indicators, and geology could not be found convincingly. Mutual correlations between 226Ra, 238U and 232Th activities were found to be high (Spearman  about 0.8), whereas the ones between these and 40K are a bit lower, somewhat above =0.6.
