The estimate of probable adverse effects on human health that may occur because of the ingestion or inhalation of radioactive substances present in these waters is relevant in Radiological Protection. The objective of this study was to determine the activity concentrations of the radionuclides 226Ra, 228Ra and 210Pb in the mineral water springs of Monte Alegre do Sul and Socorro, cities of the Paulista Water Circuit, collected in the seasons of summer, autumn, winter and spring of 2018; these cities have several mineral water springs distributed in many parts of them. The activity concentrations for the mineral waters from Monte Alegre do Sul ranged for 226Ra from limit detection of 2.2 ± 0.2 mBq L-1 to 23.0 ± 0.2 mBq L-1 , from limit detection of 3.7 ± 0.1 mBq L-1 to 16.0 ± 0,8 mBq L-1 for 228Ra and for 210Pb from the limit detection of 4.9 ± 0.4 mBq L-1 to 58 ± 5 mBq L -1 ; for Socorro ranged from limit detection of 2.2 ± 0.2 mBq L-1 to 11.0 ± 0.9 mBq L-1 for 226Ra, from limit detection of 3.7 ± 0.1 mBq L-1 to 48 ± 3 mBq L-1 for 228Ra and for 210Pb from limit detection of 4.9 ± 0.4 mBq L-1 to 49 ± 4 mBq L -1 .
