Abstract: The paper presents the results of monitoring radioactivity of soil samples in the territory Belgrade. The dependence of the concentration activity of  ²³⁸U, ²³⁵U, ²³²Th, and ¹³⁷Cs on ⁴⁰K concentration activity in soil samples is presented in this paper. According to the more than 30 measured samples it can be concluded that linear dependence between natural isotopes was observed.

Keywords: radionuclide, soil, linear dependence, monitoring, concentration.
