So this is actually good news:
1. The Rapiscan scanners (the two big boxes you'd walk between) used X-Rays and were the source of most health concerns. The L3-Communications millimeter-wave scanners (the ones, like those in Denver, that look like Eminiar Disintegration Chambers) haven't been as worrisome.
2. The scanners are being pulled not because of health concerns and lack of good and transparent testing on their effects on passengers and staff using them (which is sad), but because Rapiscan failed to meet a Congressional deadline to modify their software to produce generic images, rather than the "pornoscanner" pictures.
The units will apparently be relocated to other government facilities where, I guess, X-rays and pornoscan images aren't a concern. Or at least don't have members of the general public to complain about them.

TSA is removing these full-body scanners, but this isn't the end of naked pictures at airports.
