X-ray or millimeter wave?
If they're millimeter wave cameras then I have no (major) issue with this.
If they're x-ray, and they're scanning children... Let's just say I wouldn't want to be an MP or company executive when the first cancer lawsuits come up.
Seriously guys, x-rays are a *known* carcinogen; and that means an increase in risk, however low the dosage.
I'm aware that the dose is relatively small, but the vast majority of that dose is going directly into the surface layers of the skin. I'm pale skinned, and I've tried to avoid sun damage to my skin as much as possible to reduce my (elevated) risk of skin cancer; I don't want that undone by a few trips through the airport...
Honestly, I'd rather have a strip search than an X-ray search. Why isn't that even an option?
[Backscatter-type machines] only become somewhat worrisome when they are used as the primary method of scanning passengers, said David Brenner, director of the Center for Radiological Research at Columbia University Medical Center.
"From an individual's point of view, the risks are going to be small," Brenner said in a phone interview.
"If very large numbers of people would be exposed to a small risk, then you've got a population problem."
