RADIATION MONITORING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a radiation monitoring device that suppresses air taken in the device from being condensed into dew in a flow passage.SOLUTION: A heat exchanger 70 is provided between an intake flow passage (intake pipe 18) that delivers sucked air to a dust collection/detection part 12 and an exhaust flow passage (exhaust pipe 20) that sends out the air discharged from an air supply pump 30 to an outside. The air discharged from the air supply pump 30 is heated by the air supply pump 30 and heats the air flowing through the intake flow passage (intake pipe 18). Dew condensation is suppressed by the sucked air having an increased temperature.SELECTED DRAWING: Figure 1
