The article describes the research results obtained by the authors in geodetic monitoring of ground surface deformation with zoning and cadastral valuation of contaminated land.The primary analysis of the geodetic monitoring results is performed in terms of the Balapan site, where subsidence of ground surface reaches 5-6 mm.The findings are used in impact assessment of contamination generated at the Semipalatinsk Test Site (STS), and in development of recommendations on the use of the land in terms of radiation safety.The procedure of creation of a geodynamic test site is proposed, which allows efficient tracing of changes in ground surface deformation and adjusting cadastral valuation of land depending on its contamination level.
