Studying the treatment processes of soil samples from radionuclides

Object of research: Soil samples contaminated with radionuclides and processes for treatment soil.
 The problem to be solved: Isolation from soil by extraction weak solutions acids alkalis.
 Main scientific results: Treatment uranyl nitrate using nitric hydrochloric acid, caustic sodium subsequent washing residues distilled water is effective process leads a more than tenfold decrease in the content uranium isotopes (U238, U235, U234 U236) samples. At same time, there natural (Na22, K40, Zn65, Sn113, Sn126) extracted An increase their extract analyzed corresponds residue analysis values identical soil, but not isotopes. combined alkalis enrichment nitrates chlorine-containing compounds.
