PURPOSE:To notify a worker of spatial dose immediately, by providing an alarm for spatial dose. CONSTITUTION:A detector 3 is set at such a location as representatively registering the spatial dose of an equipment room 1 to detect changes quickly in the spatial dose rate during the working. A worker 2 moves about in a machine room 1 to conduct a task, for example, disassembly and inspection of a pump. An voice alarm 4 counts the detection value of a detector 3 and notifies the worker 2 of the newest reading, integrated value from the start of the task and residual allowable stay time in voice to hold back the dose below the preset target value. Moreover, the voice alarm 4 gives an warning to evacuate the worker 2 from the equipment room 1 when the dose reaches the target exposure value to leave no allowable work time.
