Sometimes they pat you down really quickly (might only be if they see something in the scan).
If you opt out of the new machines you can go through the old style x-ray machines, but then they do a more extensive pat-down on you, possibly with the x-ray wand thingy, and usually with their hands.
I am pretty sure if you set off the backscatter machine, you ALSO go through the other machine AND you get the more extensive pat down, too.
The old machines are not x-ray.
They are magnetic induction (or something like that). They pick up the electromagnetic distortions caused by metal going through the field they generate. Metal detectors, not x-ray.
I don't get why airports are suddenly putting in the x-ray backscatter when the other new option (mm wavelength machines) are just as accurate, cheaper, and have no radiation concerns.
And I have no intention of stripping down to my skivvies like the dude arrested in San Diego (and why did they arrest the woman who filmed it on her phone?). I'll change to lycra shorts and tank top. Probably best if I do it in the bathroom, eh?
My everything has already been patted down multiple times. I always travel with a backpack instead of luggage, so I always fit some darn profile and get "randomly" pulled for stuff. Oh, and my underwire bras used to set off the metal detectors. That part was always fun, so I've started wearing sports bras when I fly.
