METHOD FOR REMOVING CONTAMINATION OF SOIL SURFACE LAYER PART

摘要

PROBLEM TO BE SOLVED: To provide a method capable of effectively reducing a contamination level of the soil 1 by effectively removing the soil surface layer part 11 contaminated by the contaminating substances having substantially strong adsorptivity to the soil particles such as radioactive nuclear species cesium 137 falling down from the air.

SOLUTION: Plants 2 such creeping plants are grown in the soil 1 the surface layer part of which is contaminated by the contaminating substances such as the radioactive nuclear species cesium 137 or cesium 134. After growing, the plants 2 are removed from the soil 1 while cutting the roots thereof along with the soil surface layer part 11 to which the roots 22 of the plants 2 entangle in high density.
