SOIL TEXTURE IMPROVING AGENT OR IMPROVEMENT MICROORGANISM PROLIFERATION AGENT, SOIL GROUND SOLIDIFICATION METHOD, IMPROVEMENT MICROORGANISM PROLIFERATION METHOD AND DECONTAMINATION METHOD, AND DECONTAMINATION METHOD OF SOIL CONTAMINATED WITH RADIOACTIVE MATERIAL
The present invention provides a soil improvement material that mainly contains malic acid and chitin, can separate radioactive substances from soil particles by means of cultured bacteria (bacteria living in soil, such as actinomycetes; hereinafter called improvement microorganisms) in a soil contaminated with radioactive materials, has a decontamination effect increasing the decontamination efficiency, and has a soil ground improvement effect capable of giving a ground having water permeability and sufficient strength by compacting the ground due to a soil consolidation performance improvement effect. With the agent containing chitin, improvement microorganisms proliferate in a contaminated soil for 7 days to 1 month as a microorganism proliferation and curing period of the improvement microorganisms, and contaminants (cesium) are incorporated and are removed from soil particles. The present invention is a soil texture improving agent or an improvement microorganism proliferation agent as a decontamination means of a soil contaminated with radioactive substances.
