The extraction of uranyl nitrate contaminated soil with weak solutions of nitric and hydrochloric acid, caustic sodium and subsequent washing of soil residues with distilled water leads to a more than tenfold decrease in the content of uranium isotopes (U238, U235, U234, and U236) in the soil. At the same time, there is a decrease in the content of natural radionuclides (Na22, K40, Zn65, Sn113, Sn126) in the extracted soil samples. An increase in their content in the extract of the analyzed soil sample corresponds to a decrease in their content in the residue of the extracted soil sample. The combined extraction with weak solutions of these acids and alkalis leads to the enrichment of the soil with nitrates and chlorine-containing compounds of non-radioactive metals.
