X-rays are high energy radiation (for thoese not familiar in quantum physics: this is not a matter of the amout of energy in watts: it is entirely determined by the frequency of the radiation - based on Plancks formula). The actual percentage of people contracting cancer because of these scans may be low, but a high number of people multiplied by a low percentrage still is a substantial number of people. A cynical calculation would be to compare that number to the number of potential terrorist attack victims. I guess the latter i lower. But rather I would say: any checking method affecting health is *wrong*. Affecting privacy is bad enough.

They are using Terahertz radiation. Very low energy, non-ionizing, somewhere between infrared and microwave. See for example http://en.wikipedia.org/wiki/Terahertz_radiation
