FIELD: agriculture, in particular, environment protection, more particular, reduction of 137Cs level in soil. ^ SUBSTANCE: method involves growing accumulating plants such as lentils and Jerusalem artichoke on contaminated soil during three vegetation periods; alienating the entire plant biomass from soil at the end of vegetation period; determining soil cleaning extent from formula: Ceta=(Ca-Cs/Ca)*100(%), where Ceta is extent of cleaning soil; Ca is level of 137Cs in soil before planting of said accumulating plants; Cs is level of 137Cs in soil after withdrawal of the entire plant biomass from soil at the end of vegetation period. ^ EFFECT: reduced specific activity of 137Cs in soil, increased efficiency in removal of radio nuclides and obtaining of ecologically clean plant products, reduced possibility of external and internal radiation of people. ^ 2 tbl |
