PROBLEM TO BE SOLVED: To surely and efficiently confirm a decontamination effect in a decontaminated region.SOLUTION: A radioactive rate-measuring device 20 that is attached to a vehicle body 11 and performs radioactive decontamination and measurement of radioactive-rate comprises: a cleaning liquid supplying section that supplies cleaning liquid to a region R to be decontaminated; a cleaning liquid collecting section that collects the cleaning liquid from the region R to be decontaminated; a cover 23 that covers the cleaning liquid supplying section and the cleaning liquid collecting section; a scintillation fiber 25 that is provided at least on the rear side in a moving direction of the vehicle body 11 to the cover 23, extends perpendicularly to the moving direction of the vehicle body 11 and emits light in response to a radioactive ray; a signal conversion element 27 that converts the light generated at the scintillation fiber 25 into an electrical signal; and a radioactive rate-measuring section that measures a radioactive rate distribution in a longitudinal direction of the scintillation fiber 25 on the basis of the electrical signal converted by the signal conversion element 27. |
