Z-Backscatter Truck Scan(click to view full) American Science and Engineering’s Z Backscatter Van (ZBV) is a low-cost, extremely maneuverable screening system built into a commercially available delivery van. The ZBV employs AS&E’s patented Z Backscatter technology, which offers photo-like images that reveal contraband that transmission X-rays miss – such as explosives (including car bombs), people and plastic weapons – and provides photo-like imaging for rapid analysis. The ZBV is also capable of identifying low levels of radioactivity from both gamma rays and neutrons with optional Radioactive Threat Detection (RTD) technology. Here’s how it works… The Technology The basics(click to view full) A lot of organic material is low-density, and doesn’t show up well on traditional transmission X-ray images. For instance, organic matter like explosive materials contains low atomic number (low Z) elements such as carbon, oxygen, hydrogen, and nitrogen. American Science and Engineering, Inc.’s (AS&E) products creates photo-like Z Backscatter images showing organic materials by directing a sweeping beam of X-rays at the object under examination, and then measuring and plotting the intensity of scattered X-rays as a function of the beam position. Akin to light reflection, Z-Backscatter signals are particularly strong whenever the incident X-rays interact with explosives, plastics, […]
