Abstract
At system of radioactive cesium(Cs) decontamination in the forest, there are 3 bottlenecks. (1) Entry: Without concentrating Cs, the system fall into unsustainable: (2) Pathway: Transporting and/or storing the Cs contaminants is important. (3) Exit: Extreme reduction of volume of final Cs contaminants is required. Conventional process of decontamination, is a separation and transport the polluted soil. This is not a decontamination but migration. Further, temporary storage of the soil is full already. Here is the proposal to overcome each barrier, as follows: (1) The suction of the forestal Cs, by using Cs- enriched leaves.: (2) volume reduction (→1/3) of the leaf litter by the semi-carbonizing, in order to facilitate the storage and transport. (3) Mild combustion of the carbon leads control of Cs volatilization, and the Cs is concentrated onto residual ash.
