The present invention relates to a high pressure water device for decontaminating a radioactively contaminated object, which comprises: a decontamination chamber in which an object to be decontaminated is placed; a spraying nozzle spraying high pressure water to the object to be decontaminated, which is placed in the decontamination chamber; an elevating unit moving the spreading nozzle in the vertical direction of the object to be decontaminated; and a horizontally moving unit moving the spreading nozzle on the upper part of the object to be decontaminated in a horizontal direction. Therefore, a radioactive substance attached onto the surface of the object to be decontaminated can be eliminated safely and easily. 본 발명은 방사능 오염물체의 고압수 제염장치에 관한 것으로, 제염 대상물체가 안착되는 제염실, 제염실의 내부에 안착된 제염 대상물체에 고압수를 분사하는 분사노즐, 분사노즐을 방사능 오염물체의 상하방향으로 이동시키는 승강유닛, 및 분사노즐을 방사능 오염물체의 상부에서 수평방향으로 이동시키는 수평이송유닛을 포함하여, 방사능에 오염된 제염 대상물체 표면에 고착된 방사성 물질을 전체적으로 용이하고 안전하게 제거할 수 있게 된다.
