The vehicular version of the backscatter scanner looks like a panel truck or cargo van that sometimes has a big box bump-out on the back. It has an X-ray machine that can scan houses and vehicles from a distance. There's probably ones that are in buildings near border crossings etc. that don't look like trucks. The TSA is rolling these scanners out and may be scanning a street near you soon. I imagine they could use them to look for guns, electronics, gold, hidden people, or whatever the illegal thing du jour is. (guitars, lemonade, raw milk, Tea Party supporters...)
It seems the way to defeat one is with food. Keep reading.
This is from an article on
Liberty News Radio
"...the backscatter scanners coming soon to an airport or government building (or highway, in its mobile form) near you. Ironically, these purportedly protect you from dirty bombs by irradiating you today (and tomorrow, and the next day, and so on). But then again, these are defeated, or confused, by simply packing the sides, bottom and top of the cargo area with cases of innocuous "low-Z" substances. Like sugar. Or flour..."

This sort of reminds me of my article about building a makeshift fallout shelter. To avoid the radiation emanating from fallout outside, you get in the center of the house (away from the outside walls) and build a fort around yourself with thick stuff, like boxes of books. I'm guessing this is sort of the same idea. You're essentially insulating yourself or your cargo from radiation with thickness. I wish it had said how much sugar you might need.
The rest of the Liberty News Radio article that mentions how to shield from backscatter is a theoretical discussion of how a radiological attack could be done by scattering some stuff disguised as mud or road salt, made from some mysterious "Substance A" and "Substance B". Sort of interesting, but I hope nobody is stupid enough to try it.
