Summary:Detecting characteristics of a test subject at a checkpoint. Embodiments may include exposing a single test subject to electromagnetic radiation at a security checkpoint. They may further include determining how the electromagnetic radiation interacts with different portions of the single test subject. They may further include determining different material properties for the different portions of the single test subject by examining how the electromagnetic radiation interacts with the different portions of the single test subject. They may further include providing an indication of the different material properties of the different portions of the single test subject, wherein providing an indication of the different material properties of the different portions of the single test subject comprises distinguishing between different material properties.
