A survey of radium activity concentrations in well and spring waters in Serbia was conducted and their correlations with geological formations were analysed. Water samples were collected from 170 sampling sites and analysed by gamma-ray spectrometry. The mean activity concentrations of Ra-226 were found to be 0.36 Bq L-1 and 0.57 Bq L-1 in well and spring waters, respectively. In more than 90% of the analysed waters the Ra-226 activity concentrations were below 1 Bq L-1. The highest activity concentrations of this radionuclide (up to 17 Bq L-1) were found in crystalline rocks- and carbon dioxide rich-aquifers. The mapping results provide a baseline to identify regions that may require additional assessment of radiation exposure by local communities. (C) 2011 Elsevier By. All rights reserved.
