Some international organizations indicate that it is necessary to know the contamination of drinking-water, including radioactive aspects. The novelty of this study was to determine simultaneously radioisotope Ra, Th, U and Pb stable by magnetic sector mass spectrometry. Experiments were performed in an accredited laboratory (ISO/IEC-17025:2005). The radionuclides of Th, U and some of their descendants were detected. The reported values are in the range of 7x10-7-24.28 µg L-1.
