PROBLEM TO BE SOLVED: To provide a method for decontaminating the farm and the forest which are contaminated with cesium by the explosion of the atomic bomb so that a restoration of the agriculture and forestry is made difficult, reducing the storage amount to a possible level, minimizing an intermediate storage processing space which is the maximum difficulty of the decontamination project, and suppressing devastation of the radiated farm contaminated and devastated by weeds and injurious insects as much as possible, and a flow thereof.SOLUTION: The method for reducing and decontaminating forest trees successively and in a cascading manner is provided in which a corrosion layer of the forest extremely contaminated with cesium is eliminated and decontaminated, and a trunk of the tree grown there is made into chips to be mulched. Contaminated leaves, branches, and barks are burned or fermented, and contaminants are concentrated and reduced in volume. Consequently, the difficulty of securing an intermediate storage site is alleviated, and heated water of a low temperature is obtained by combustion heat so as to dry the chips at the low temperature. An allelopathy component for suppressing weeds and injurious insects is extracted from sap which is collected at the lower temperature drying time and given to the farm until tillage is implemented, thereby facilitating the restoration of the agriculture.COPYRIGHT: (C)2014,JPO&INPIT【課題】原発爆破に依りセシウム汚染され農林業復興を困難としている農地と山林を除染し、貯蔵量を可能なレベル迄減容化し、除染事業の最大の難点である中間貯蔵処理スペースを極小化し、また、放散し雑草や害虫に汚染荒廃される農地の荒廃を可能な限り抑制する方法、フローを提供する。【解決手段】最もセシウム汚染されている森林の腐蝕層をはぎ取り除染し、そこに生えていた樹の樹幹部をチップ化し、マルチングする。汚染した葉・枝・バークを燃焼あるいは発酵させ汚染物を濃縮減容化し、中間貯蔵地確保の困難を緩和し、燃焼熱より低温の加熱水を得て、チップを低温乾燥し、低温乾燥時に回収する樹液水より雑草と害虫を抑制するアレロパシー成分を抽出して、耕耘に至るまでの農地に投与して農業復興を容易にすることができる汚染地を逐次波及的に除染する森林木材減容化除染法。【選択図】図2
