する全身表面汚染モニタ。[Scope of Claim for Utility Model Registration] 1. It is installed at the boundary between the radiation control area and the general area, and the counting rate due to the surrounding space is calculated from the total counting rate measured when the person to be measured enters through the entrance door and closes this entrance door. In a whole body surface contamination monitor that calculates the net count rate due to radioactive substances attached to the whole body surface of the subject by subtraction, the entrance door is closed when the subject is not inside the whole body surface contamination monitor. A whole-body surface contamination monitor comprising surrounding space count rate measuring means provided to measure the counting rate in the surrounding space. 2. Scope of Utility Model Registration Claims In the whole body surface contamination monitor set forth in claim 1, the surrounding space count rate measuring means is provided on the entrance door side of the whole body surface contamination monitor and is configured to measure the total count rate of the subject. or a whole-body surface contamination monitor characterized by having a display device that can determine from the outside whether the surrounding space count rate is being measured. 3. Scope of Utility Model Registration In the whole body surface contamination monitor set forth in claim 1, the surrounding space count rate measuring means includes a detection device for detecting the presence or absence of a person to be measured from outside the closed entrance door. Features a whole body surface contamination monitor.
