A scanning system is for trace detection. The scanning system includes a main body enclosing a scanning chamber, the main body including a chamber inlet; a transport system configured to move an article through the scanning chamber along a scanning path; and a door mechanism provided along the scanning path. The door mechanism includes: a door frame mounted about the scanning path; at least one door panel movable relative to the door frame and being made of a radiation-shielding material; and a trace detector integrated into the at least one door panel. A method for trace involves using trace detectors integrated into the door mechanism for trace detection while the object is moving along a scanning path passing through a scanning chamber of a scanning system.
