American Science and Engineering, Inc has developed a mobile version of those naked imaging, cancer causing, backscatter machines that are used at airports. Yes, Homeland Security will soon be able to cruise down your street and check out what is really going on under your clothes.
This is from the AS&E web site:
A breakthrough in X-ray detection technology, AS&E's Z Backscatter Van™ (ZBV) is a low-cost, extremely maneuverable screening system built into a commercially available delivery van. The ZBV allows for immediate deployment in response to security threats, and its high throughput capability facilitates rapid inspections. The system's unique "drive-by" capability allows one or two operators to conduct X-ray imaging of suspect vehicles and objects while the ZBV drives past.Read more:
The ZBV can also be operated in stationary mode* by parking the system and producing X-ray images of vehicles as they pass by. Screening can also be accomplished remotely while the system is parked. Remote operation allows scanning to be done safely, even in dangerous environments, while maintaining low-profile operation. The system is unobtrusive, as it maintains the outward appearance of an ordinary van.
