The content of radionuclides (K-40 , U-238 , Ra-226 , Th-232, and Cs-137) and heavy metals (As, Cd, Cu, and Pb) was determined in samples of soil, vegetables and medicinal plants collected in the period 2007-2017, from two suburban areas of Belgrade - the municipalities of Palilula and Surcin, and Pancevo - the Dr Josif Pancic Institute for the Study of Medicinal Herbs. During the research period, activity concentration of Cs-137 in soil decreased from 16 Bqkg(-1) to 3.9 Bqkg(-1) (Palilula, Belgrade) and from 18 Bqkg(-1) to 12 Bqkg(-1) (Surcin, Belgrade). Mean activity concentrations of natural radionuclides in the soil were higher than the global average. lkend for heavy metal levels, according to the average concentrations found in the soil, were as follows: Cu >Pb >As >Cd for Palilula, Pb >Cu >As >Cd for Surcin and Dr Josif Pancic Institute, Pancevo. The obtained results indicate that the industrial pollution has no impact on food production in the study area and that the main anthr...opogenic source of radionuclides and heavy metals in soil are mineral phosphorous fertilizers, often used in agricultural fields.
