Lindsay Beyerstein: Pilots’ Unions Say ‘No’ to Invasive TSA Airport Scans

[This is what the government spent 200+ million dollars of "recovery act" funds on? Come on Americans, is this how you want to live your lives?]

Pilots’ Unions Say ‘No’ to Invasive TSA Airport Scans
By Lindsay Beyerstein
In These Times

The nation's largest pilot's union, the Allied Pilots' Association, urged its 11,500 members to boycott the TSA's whole body scanners, which use x-rays to render a very lifelike nude portrait of the subject. The TSA installed new "Advanced Imaging Technology" scanners in 65 more airports earlier this month.

For those passengers who refuse to play a nude bit part in the security theater, the TSA has launched a new line of more invasive body searches in October, Consumerist reports:

"To call it a pat-down is a euphemism," said a spokesman for the ACLU in Massachusetts. "They really go for it."

He says that -- unlike the antiquated pat-down, which required TSA screeners to use the back of their hands when searching sensitive regions of your person -- the enhandced pat-down allows them to use their palms and fingers to feel and prod passengers.


Dave Bates, president of the Allied Pilots Association, told ABC News that pilots are already exposed to high levels of radiation simply from flying. Radiation exposure is cumulative. The union is concered about the potential consequences of piling even more raditiation into their day-to-day routine.

The unions point out that pilots fly an average of 15-18 days each month and may face two or three scans each day. The radiation exposure from a scan is about 1/2000th the amount of a chest x-ray.

The alternative isn't appealing to pilots, either. In a message to his brother and sister pilots, Bates described the "enhanced" pat-down as a "demeaning experience."

"In my view, it is unacceptable to submit to one in public while wearing the uniform of a professional airline pilot," he wrote, "I recommend that all pilots insist that such screening is performed in an out-of-view area to protect their privacy and dignity."

Dave Lindorff: Forget Radar, Now the Government Is X-Raying You as You Drive

Getting Some Rays: Forget Radar, Now the Government Is X-Raying You as You Drive

If you have been feeling uneasy about having to be X-rayed by a Transportation Security Administration goon who can look under your clothes every time you fly, consider this: at least you can say no, and agree to be subjected to an old-fashioned full-body search.

No opt-out for the latest in anti-terror technology though, with reports just out in Forbes Magazine and the Christian Science Monitor that the Homeland Security Department has purchased 500 mobile X-ray vans called ZBVs that can scan cars, trucks and homes without the drivers even knowing that they're being zapped.

These vans, made by a Massachusetts company called American Science & Engineering, are fitted out with what are called Z Backscatter X-ray devices, which aim a focused X-ray beam that reportedly has the capability of penetrating 14 inches of steel.

In theory, the device is supposed to be safe for human targets, because it is operated at a distance, and because the beam is weakened by penetrating the metal of a vehicle before it reaches a person. But the flaws in this kind of reassuring safety calculus are readily apparent in a photo of a small truck carrying contraband that accompanies the Christian Science Monitor story. The X-ray image, after penetrating the truck cab's metal body, clearly shows the contraband behind the driver's seat, but it also just as clearly shows the shadowy outline of the driver of the pickup. Worse yet, even his window is half-way down, so there is no shielding at all of the X-rays hitting his head.

We can expect these mobile X-ray vans to be proliferating around the country soon, if they're not out there already, but they may be hard to spot. As American Science & Engineering says in a note to investors on the company website:

A breakthrough in X-ray detection technology, AS&E's Z Backscatter Van is the number one selling non-intrusive mobile inspection system on the market. The ZBV system is a low-cost, highly mobile screening system built into a commercially available delivery van.

Prof. Peter Rez, a physicist a Arizona State University who specializes in X-ray technology, and who has been doing research on backscatter X-ray dosages, says that if used properly, the radiation doses received by targeted persons would be very minute, but then he notes that if the government begins a major campaign of surreptitious X-raying on highways and at locations of security concern (the machines are already being used at major sporting events like the Superbowl), there have to be concerns about whether the machines are being maintained in proper working condition (driving them around on America's run-down highways is subjecting the machines to quite a beating), and about whether the operators are using them properly.
