Abstract: Significant regression dependencies between ambient equivalent dose rate and ¹³⁷Cs contamination density, as well as between ¹³⁷Cs and ⁹⁰Sr contamination densities were obtained. An economically inexpensive approach to estimating the density of soil contamination by ¹³⁷Cs, ⁹⁰Sr, and plutonium isotopes with controlled uncertainties has been proposed and tested. The approach allows also the immediate evaluation of the density of radionuclide soil contamination even if there is a contamination gradient within the agricultural land.

Keywords: ¹³⁷Cs, ⁹⁰Sr, soil, radioactive contamination, Chornobyl accident.
