SOIL REHABILITATION METHOD Russian patent published in 1996 - IPC

FIELD: soil amelioration, in particular, rehabilitation of radioactive nuclide affected soil. SUBSTANCE: method involves applying ground clinoptilolite with particle size of 5-30 mm in an amount of 30% with respect to quantity of soil to be rehabilitated to provide reliable binding of radioactive nuclides by structure of clinoptilolite; removing clinoptilolite from soil by sieving. Amount of clinoptilolite introduced into soil depends also on composition of soil to be rehabilitated as well as on land area affected by radioactive nuclides. EFFECT: increased efficiency, improved quality of soil.
