| What's new is the ability of these vans to "drive by" whole streets at normal speed and examine each and every vehicle it passes. The manufacturer's website describes this capability in more detail and provides a video, complete with cheerful music, showing how the equipment can turn everything it passes into the opacity of clear glass. The backscatter X-ray is tuned to organic wavelengths, enabling it to find hidden people and explosive. But this is not all it can do. For an optional extra, the Z-Backscatter Van can also find those pesky dirty bombs and nuclear weapons that every well-managed city wants to be rid of, all at a low price and in an environmentally responsible manner: getting frisked by the Z-Backscatter Van only requires an exposure equivalent to a fifteen minute flight on a commercial aircraft. |
