Getting a different picture when it comes to airport X-rays...

"Unsafe At Any Scan?"

According to a researcher at the University of California, Davis, there are serious health questions surrounding the use of backscatter radiation scanners (aka: "porno-scanners") now being employed at U.S. airports.

Background: Jason Bell, a molecular biologist and biophysicist working in a research lab at UC Davis, notes that the lab "(as well as many others) has spent the better part of the last decade working on the molecular mechanism of how mutations in the breast cancer susceptibility gene, BRCA2, result in cancer. The result of that work is that we now better understand that people who have a deficient BRCA2 gene are hypersensitive to DNA damage, which can be caused by a number of factors including: UV exposure, oxidative stress, improper chromosomal replication and segregation, and radiation exposure."

At his blog, My Helical Tryst, Bell has posted a detailed critique of the research on the safety of airport backscatter radiation scanners. It's "a detailed, lay-friendly explanation of the scientific concerns expressed by the [research] team that believes that they are unsafe for use:

"[How] the scanner works: Essentially, it appears that an X-ray beam is rastered across the body, which highlights the importance of one of the specific concerns raised by [the researchers]... what happens if the machine fails, or gets stuck, during a raster. How much radiation would a person's eye, hand, testicle, stomach, etc be exposed to during such a failure. What is the failure rate of these machines? What is the failure rate in an operational environment? Who services the machine? What is the decay rate of the filter? What is the decay rate of the shielding material? What is the variability in the power of the X-ray source during the manufacturing process? This last question may seem trivial; however, the Johns Hopkins Applied Physics Laboratory noted significant differences in their test models, which were supposed to be precisely up to spec. Its also interesting to note that the Johns Hopkins Applied Physics Laboratory criticized other reports from NIST (the National Institute of Standards and Technology) and a group called Medical and Health Physics Consulting for testing the machine while one of the two X-ray sources was disabled (citations at the bottom of the page).

These questions have not been answered to any satisfaction and the UCSF scientists, all esteemed in their fields and members of the National Academy of Sciences have been dismissed based on a couple of reports seemingly hastily put together by mid-level government lab technicians. The documents that I have reviewed thus far either have NO AUTHOR CREDITS or are NOT authored by anyone with either a Ph.D. or a M.D., raising serious concerns of the extent of the expertise of the individuals and organizations evaluating these machines. Yet, the FDA and TSA continue to dismiss some of the most talented scientists in the country...

Furthermore, when making this comparison, the TSA and FDA are calculating that the dose is absorbed throughout the body. According the simulations performed by NIST, the relative absorption of the radiation is ~20-35-fold higher in the skin, breast, testes and thymus than the brain, or 7-12-fold higher than bone marrow. So a total body dose is misleading, because there is differential absorption in some tissues. Of particular concern is radiation exposure to the testes, which could result in infertility or birth defects, and breasts for women who might carry a BRCA1 or BRCA2 mutation. Even more alarming is that because the radiation energy is the same for all adults, children or infants, the relative absorbed dose is twice as high for small children and infants because they have a smaller body mass (both total and tissue specific) to distribute the dose. Alarmingly, the radiation dose to an infant's testes and skeleton is 60-fold higher than the absorbed dose to an adult brain!

"What happens to a chromosome of a normal cell when it is exposed to radiation. It most cases, this damage is repaired; however, at high doses or when there is a genetic defect, the cells either die or become cancerous."

Giving thanks...

...and getting an aggressive pat-down?

In preparation for Thanksgiving Day, many around the nation will be making their way to loved ones' homes, via - yes - "trains, planes and automobiles." And much like the hapless characters from the movie of the same name, starring Steve Martin and the late John Candy, holiday travelers will be facing all sorts of challenges.

Especially if they choose to fly.

By now, we've heard countless stories of invasive pat-downs, "porno scans" and other assaults on the dignity of the American flying public...all in an effort to quash terrorism!

Now, along with having to deal with TSA's play on the administration mantra, "Grope and Change," fliers - frequent and otherwise - now have to contend with a list of "no-nos." The list (supplied by The Folks Who Feel You Up), doesn't cover sharp objects, items that can be used to club people with, or anything remotely construed as a possible weapon.

Here's the TSA's list of "Foods That Don't Fly." (Man, I am so glad Uncle Al Qaeda won't be bringing his lousy cranberry sauce again this year!)

Traveling with Food or Gifts

How to Pack Food and Gift Items

When it comes to bringing items through checkpoints, we've seen just about everything. Traveling with food or gifts is an even bigger challenge. Everyone has favorite foods from home that they want to bring to holiday dinners, or items from their destination that they want to bring back home.
Not sure about what you can and can't bring through the checkpoint? Here's a list of liquid, aerosol and gel items that you should put in your checked bag, ship ahead, or leave at home.

• Cranberry sauce

• Cologne

• Creamy dips and spreads

• (cheeses, peanut butter, etc.)

• Gift baskets with food items

• (salsa, jams and salad dressings)

• Gravy

• Jams

• Jellies

• Lotions

• Maple syrup
• Oils and vinegars
• Perfume
• Salad dressing
• Salsa
• Sauces
• Snowglobes
• Soups
• Wine, liquor and beer

Note: You can bring pies and cakes through the security checkpoint, but please be advised that they are subject to additional screening.

Remember! – do not wrap gifts you're taking on the plane. Security officers may have to unwrap gifts if they need to take a closer look. Please ship wrapped gifts ahead of time or wait until your destination to wrap them.

Gloria Allred On TSA Pat-Downs:

"I Liked It"

The last time Gloria Allred actually shut up...

Gloria Allred, the infamous ambulance-chasing, attention-whoring attorney - who most recently gained notice for her efforts to undermine Meg Whitman's campaign for governor of California - explains why she thinks invasive TSA searches are OK...

Here's the exchange (from Nov. 19):

SEAN HANNITY, HOST: "Did they touch your body parts?"

GLORIA ALLRED: "Yeah, they did and it was a first time anybody touched them in a long time and frankly, I liked it."

Allred, the self- (and TSA-) satisfied watchdog...

Hillary - on the fly...

More TSA patter:

Earlier today, CBS' "Face the Nation" host Bob Schieffer asked Sec. of State Hillary Clinton if she would submit to a TSA pat-down.

HRC: "Not if I could avoid it. No. I mean who would?"

Exactly - who would?

"We know you don't have a choice when you fly..."

More TSA fun...
