PROBLEM TO BE SOLVED: To acquire a vehicle gate monitor capable of monitoring a contamination state of a radioactive substance on a vehicle surface speedily and precisely.SOLUTION: A detector group (22) is composed of a first detector that is disposed so as to permit vertical/horizontal movement according to a relative position to a vehicle, and measures a radiation dose on both side surfaces of the vehicle, a second detector that is disposed so as to permit vertical/horizontal movement according to the relative position to the vehicle, and measures a radiation dose on a front surface, a rear surface, a top surface, and a deck surface of the vehicle, and a third detector that is disposed so as to permit vertical/horizontal movement according to the relative position to the vehicle, and measures a radiation dose on an internal side surface of the deck. A vehicle gate monitor includes a control part (21) for identifying presence or absence of a contamination place, based on a detection result acquired from the detector group, while moving a gate shape in that the detector group (22) is attached relative to a stopped vehicle.SELECTED DRAWING: Figure 2 |
