occurrence of carbonated groundwater (MARINKOVIĆ et al. 2012). This groundwater also exhibits naturally elevated radioactivity. ConclusionIn this paper the distribution of natural radioactivity of groundwater from the territorywater originates from these rocks (PROTIĆ 1995).Groundwater occurrences mark different regional geological-structural features and the largest number ofmineral groundwater is related to the granite intrusions and volcanic
samples that exhibited elevated betaactivity concentrations belonged to the Na-HCO3 typeof groundwater, suggesting that the groundwater tracedto an aquifer in granitoid rocks with elevated concentrations of dissolved solids
