Abstract: The purpose of this of this research is to determine ²²⁸Ra, ²²⁶Ra and ²¹⁰Pb concentrations in the water and sediment of the São Francisco River, nearby from farms producing fruits in Petrolina City. Concentrations of ²²⁸Ra, ²¹⁰Pb and ²²⁶Ra in the water samples varied from <19.0 (detection limit) to 22.0 mBq.l⁻¹; <4.0 (detection limit) to 13.0 mBq.l⁻¹; and 12.0 to 42.0 mBq.l⁻¹, respectively. For sediments samples, in this order, the concentrations ranged from <7.0 (detection limit) to 35.0 Bq.kg⁻¹; <3.5 (detection limit) to 15.0 Bq.kg⁻¹; and 12.0 to 92 Bq.kg⁻¹. These results indicate that there are spots in São Francisco River, Petrolina, which have high concentrations of ²²⁸Ra, ²²⁶Ra and ²¹⁰Pb in sediments.
