Resumen
This paper aims at quantifying natural and artificial radionuclides, trace and major elements in sediments collected along the Tiet?? River basin. The results obtained for Cd, Cr, Cu, Ni and Zn, indicated that the region of ???High Tiet????? is highly polluted, followed by the region of ???Middle Tiet????? and the region of ???Low Tiet????? does not present evidence of contamination. The natural radionuclide concentrations were of the same order of magnitude of world average values and can be defined as basal levels of the region. Cesium-137 activity concentration ranged from 0.22????????0.08 Bq kg???1 to 0.96????????0.12 Bq kg???1. Funda????o de Amparo ??
