How about opting out on the basis of no FDA approval of the machines.

Full-body scanners used on air passengers may damage human DNA calling out...
[quote author=Mike Adams, NaturalNews.com]There have been no clinical trials indicating that multiple exposures to such terahertz waves, accumulated over a long period of time, are safe for humans. The FDA, in particular, has never granted its approval for any such devices even though these devices clearly qualify as "medical devices."[/quote]

[quote author=Mike Adams, NaturalNews.com]Sure, you can argue that you get more radiation sitting in an airplane at high altitude than you get from a full-body scanner, or you can explain that cell phones emit far more radiation on the whole (which they do, when you're talking on them anyway). But if there's one thing we all should have learned about radiation by now it's that
frequencies matter. The terahertz frequencies have never been rolled out en masse in a scanning technology. Who's to say they're going to be safe?[/quote]
I think this above cited NaturalNews article does a good job highlighting the dubiousness of the endorsements from the Radiologists and TSA. But DailyTech.com takes on the absurd TSA assertion that the scanners "can't be networked" with
TSA Called Out on Full-Body Scanner Storage Capabilities, Health Risks Revealed.
[quote author=Jason Mick, DailyTech]Well, at least the scanners can't send or store images, said advocates. However, that turns out to be a false claim as well. The Electronic Privacy Information Center (EPIC) has received 2008 documents from the TSA which not only clearly state that the scanners could have such abilities, but they say that the scanners must have them.
The TSA documents state that all scanners need to be capable of storing and sending user images when in "test mode". Those documents, obtained by a Freedom of Information Act request, catch the TSA in an apparent lie. It's website claims, "The machines have zero storage capability."[/quote]

Look Out X-rays, T-rays Will Change Domestic Security revealing how we're dealing with T-rays here, not X-rays explaining... [quote author=Wofgang Hansson, DailyTech]
T-rays, or terahertz rays, function similarly to x-rays or any other electromagnetic radiation. However, whereas x-rays radiate at frequencies above the visible light spectrum, t-rays operate just below it. High-frequency t-rays is actually low-frequency infra-red radiation.[/quote]
I'm glad to discover this issue getting wider coverage, but whenever prisonplanet.com latches onto an issue it makes me wonder what sort of cointel interests Israel has in the matter.
