Sediment samples from the Tisza River in Serbia were investigated for possible TENORM pollutants. The radionuclide content of the samples was determined by means of low-level high-resolution gamma-spectroscopy. In addition to the members of the natural radioactive chains of ^<238>U and ^<232>Th and the natural ^<40>K, Chernobyl origin ^<137>Cs was detected in 26 of the 28 samples tested. The higher concentration of ^<238>U in four locations along the river could be caused by extensive exploitation of phosphate fertilizers in the surrounding agricultural area (TENORM). Also, in one location the lowest ^<40>K and the highest ^<232>Th concentration in all samples were detected. Every unexpected distribution is an indication of radio-active contamination.
