Activity concentrations of ⁴⁰K, ²³⁸U, ²³²Th and ¹³⁷Cs in the samples of cultivated and uncultivated soil, mosses, mushrooms and game meat (wild rabbit, pheasant and wild boar) are measured by the gamma spectrometry technique. The samples were collected in suburban areas of Belgrade, Serbia, in the period from 2008–2014. The mean activity concentrations of ⁴⁰K, ²³⁸U and ²³²Th in cultivated soil аre 637 Bq·kg^-1, 52 Bq·kg^-1 and 53 Bq·kg^-1, and in uncultivated soil 608 Bq·kg^-1, 58 Bq·kg^-1 and 55 Bq·kg^-1, respectively. An artificial radionuclide ¹³⁷Cs is detected in the samples of soil, mosses and mushrooms, which indicates that almost 30 years after the nuclear accident in Chernobyl, ¹³⁷Cs is still present in the environment. Since the activity concentrations of primordial radionuclides and ¹³⁷Cs in game meat are below detection limit, these samples can be classified as safe for consumption.
