ABSTRACT:
A hazardous material detection system that can suppress occurrence of contamination due to ionization. When a sensor detects that a test sample has entered an inspection region of an X-ray inspection device as a belt conveyor moves, a corona discharge power supply in a hazardous material detection device is turned on for a constant time, to introduce a qaseous sample containing a substance stuck to the test sample into the hazardous material detection device via a sucking section and gaseous sample introduction piping, in order to ionize the gaseous sample and analyze it at an analyzer, based on a result of which analysis, a data processor decides whether the gaseous sample contains a hazardous material, to display a decision result on a screen. When the test sample is detected by an exit side sensor, the corona discharge power supply is turned off.
