The only thing I have seen mentioned in the link Carver provided is the radiation detectors. They're set up at scales and have thermal sensors as well. Funny thing though, I was enduring an inspection in Ky and a truck rolled through and set off the radiation alarm. The truck was loaded with red facing bricks (the ones with holes in them). The inspector told me it happens every time a load of bricks goes through.
