ABSTRACT:
A tray for holding an article while the article is being subjected to penetrating radiation is provided. The tray has a surface on which the article can be placed while subjected to penetrating radiation. The surface has at least two areas, namely a first area and a second area, the first and second areas characterized by first and second signatures, respectively when exposed to penetrating radiation, wherein the first signature is different from the second signature. The second area corresponds to a reference material having a reference signature. The tray is placed on the conveyor belt of a scanning apparatus while the article rests on the surface of the tray so that the conveyor belt may advance the tray through the screening area of the apparatus. A method and system for performing security screening and using the tray are also provided.
