Abstract
A baggage inspection system has a conveyor path disposed between an X-ray source, which genertes an X-ray beam, and a radiation detector for detecting radiation passing through articles on the conveyor path. The conveyor path is formed by two surfaces disposed at a right angle relative to each other, with the right angle being inclined relative to the horizontal so that articles on the conveyor path are forced by gravity to lie against one of the surfaces. At least one of the surfaces is a moveable surface, and the other surface may also be a moveable surface, or a roller surface or a plate against which the articles slide. The radiation detector may be an angled detector row so as to encompass substantially all of the radiation beam within its field of view.
