DIFFUSION PREVENTION AND DECONTAMINATION METHOD OF RADIOACTIVE SUBSTANCE ACCUMULATED IN MOUNTAIN FOREST

摘要

PROBLEM TO BE SOLVED: To provide diffusion prevention and decontamination methods of radioactive substances in mountain forests by constructing a facility in combination with an intermediate storage facility and a final treatment site.;SOLUTION: Disclosed are diffusion prevention and decontamination methods of radioactive substances accumulated in mountain forests with a slope. A plurality of ditch pits are dug up in the mountain forest, and radioactive substance adsorption agents are spread all over the dug up ditch pits. Diffusion of the radioactive substance is prevented by accumulating the radioactive contaminated water and contaminated soils eluted from earth of the mountain forest in the ditch pits, and decontamination is performed by adsorbing the radioactive substance with the radioactive substance adsorption agents in the ditch pit.;COPYRIGHT: (C)2014,JPO&INPIT
