DECONTAMINATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a decontamination system capable of increasing decontamination efficiency without a temporary inspection yard for decontamination confirmation.SOLUTION: There is provided a decontamination system which comprises: a first classifier 10 for comparing a radiation level of contaminated soils and a processing limit value to classify the contaminated soils into processable soils whose radiation level is below the processing limit value and soils containing a high level of radiation exceeding the processing limit value; a purifier 20 for purifying the processable soils to reduce their radiation level and discharging the soils as the processed soils; and a second classifier 30 for comparing a radiation level of the processed soils discharged from the purifier 20 and a purification reference value to classify the processed soils into purified soils whose radiation level is below the purification reference value and soils to be reprocessed containing a high level of radiation exceeding the purification reference value. The soils classified as processable by the first classifier 10 and the soils as something to be reprocessed by the second classifier 30 are placed in the purifier 20 as the soils to be processed.SELECTED DRAWING: Figure 1
