ABSTRACT:
A method for performing security screening of a liquid product at a security checkpoint is provided. The liquid product is placed in a tray having at least two reference areas manifesting respective X-ray signatures when exposed to X-rays, the X-ray signatures being distinguishable from one another. An X-ray inspection of the tray is performed while the tray holds the liquid product, the X-ray inspection including deriving the X-ray signatures. A determination is made as to whether the liquid product is a security threat at least in part based on the X-ray signatures. A tray having at least two reference areas manifesting respective X-ray signatures when exposed to X-rays is also provided.
