Keywords: soil, cesium 137, strontium 90, chemical treatment, plants
Abstract: The method of cleaning consists of infusion of chemical materials into the soil. Topsoil is covered by limestone or dolomite flour (5-6 tons per hectare), with potash KCl, KNO3 or KMgCl 3.6 H2O in an amount of not less than 200 kg per hectare. This process is followed by plantation of mixture of perennial grasses, which are mowed in autumn and placed in storage, precluding the migration of radionuclides.
