Z BACKSCATTER TECHNOLOGY WAS PIONEERED, PATENTED, AND PERFECTED BY AS&E.
It is the proven approach for the discrimination of organic materials such as explosives, drugs, cigarettes, and people, especially when hidden within a complex environment.
- The photo-like images are easy-to-interpret, revealing both the presence and exact position of organic components of the scanned object.
- It is the most effective X-ray technology for the detection of organic materials.
HOW DO X-RAYS WORK?
When X-rays interact with matter, they do one of three things:
- Pass through the object
- Get absorbed by the object
- Scatter from the object
Objects with higher density absorb more X-rays than objects with lesser density. Much organic material is low-density and X-rays scatter when they interact with organic objects.
Traditional transmission X-ray images like medical X-rays result when X-rays pass through an object to a detector located on the far side of the object. The resulting image is bright where most of the X-rays pass through the object and dark where most X-rays are absorbed.
