摘要：A hazardous material detection system that can suppress occurrence ofcontamination due to ionization. When a sensor detects that a test sample has enteredan 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 aconstant time, to introduce a gaseous sample containing a substance stuck to the testsample into the hazardous material detection device via a sucking section and gaseoussample introduction piping, in order to ionize the gaseous sample and analyze it at ananalyzer, based on a result of which analysis, a data processor decides whether thegaseous 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 powersupply is turned off.
