FIELD: physics.
SUBSTANCE: method of cleaning soil contaminated with a strontium radionuclide involves cutting and removing vegetation, adding lime and tilling the soil. After removing vegetation, the soil on the contaminated area is loosened at a depth of 1.2-1.5 m while feeding carbon dioxide gas into the bottom part of the loosened layer and water-retaining rolls are filled around the area after adding lime and tilling.
EFFECT: invention increases efficiency of fixing the strontium isotope outside the root layer.
