PROBLEM TO BE SOLVED: To provide a charcoal filter inspection method capable of improving measurement accuracy for an iodine adsorption distribution and improving calculation accuracy for iodine removal efficiency.SOLUTION: A pretreatment is executed for removing pulverized coal from a filter cartridge filled with sampled granular active carbon in 110; a plurality of filter cartridges is superimposed in 120; radioactive iodine flows to the superimposed filter cartridges in 140; and iodine adsorption energy of each of the filter cartridges is measured and an iodine adsorption distribution in a filter thickness direction is measured in 150 after 140; and iodine adsorption efficiency is calculated on the basis of this iodine adsorption distribution in 160.SELECTED DRAWING: Figure 1 |
