The embedded video is dead, but I assume this is the same one: http://www.youtube.com/watch?v=VHRlXzRfvpA http://www.youtube.com/watch?v=VHRlXzRfvpA Edit: the video claims radiation exposure is equivalent to a 15 minute airplane ride.

Thanks for the link. I wonder how hard it would be to make a wave guide for this band. Or of course a cloaking device which obscures THz frequencies. On the one hand I'm all in favor of driving these around where there may be active IED activity but less thrilled about having them randomly running through traffic, only to suddenly pull me over because I've got 3 bags of fertilizer for my new grass sod lawn. The older I get the more I realize I haven't thought too hard about the downside of living in the kind of places one reads about in science fiction.

    I wonder how hard it is to make a device which homes in on X-ray devices.... you know... to guide some sort of thing to an x-ray source..... yeah, I agree. That's a bad idea.

I'm sure it detects all manner of organic and explosive material, like fuel in fuel tanks, and brake fluid and sump oil, and shopping from the supermarket. Of course you should be able to shield yourself from the harmful effects of the X-rays by sitting behind a thin wall of metal, for example the metal making up your car's body.... Why don't I believe a word of this.

"the video claims radiation exposure is equivalent to a 15 minute airplane ride." That's also the claim the TSA makes about the body-scanners in the airports, yet these are dramatically more powerful (to be able to see through metal). Google (image search) a bit "scanner van" and you'll see these things can penetrate multiple layers of steel (pickup truck bodies, etc.) with no problem. That takes a wee bit more power than looking through cotton jeans and underwear. Don't forget about the TSA cancer cluster... or the fact that the TSA lied outwardly about the safety of the devices (stating the NIST, which doesn't perform product testing, tested the body scanners and certified them as safe).
