PROBLEM TO BE SOLVED: To provide a decontamination apparatus having a compact configuration and capable of simply and reliably performing decontamination of radioactive substances.SOLUTION: A decontamination apparatus 1, when performing decontamination work by ultrasonic vibrating a vibrator 3 by ultrasonic vibration means 2, uses a brush part 4 configured so that a plurality of brush hairs 41 whose tips 411 are arranged to face a decontamination target are arranged on a brush plate 42 so as to surround the vibrator 3 arranged to face the decontamination target. Since the decontamination apparatus can hold liquid between adjacent brush hairs 41 during the decontamination work in spite of a compact configuration, the decontamination apparatus can simply and reliably perform decontamination of radioactive substances and can be applied to decontamination work of soil, roofs, walls, floors, and so on. |
