People blindly repeat the above, who have no clue what they are talking about. Dismissing the risks outright, is pure ignorance.

First off - perhaps you could supply your educational, scientific and/or medical credentials. Perhaps you have more credibility than four esteemed scientists/doctors at UCSF, one of the premier medical and imaging centers in the world who share a slightly different opinion on the subject from you.

But hey - I'll even give you the benefit of the doubt, and assume you're more all knowing in the field than these experts. Let's assume your risk assessment is correct.

If so, the number floating about by the naysayers is that "only" 1 in 30 million people will contract cancer from a single backscatter machine exposure. Given that over 800 million people fly each year, the TSA is responsible for killing only 27 folks. So, the TSA kills more people than terrorists from the scans alone.

Of course, it doesn't stop there. With the increased number of people refusing to fly while this nonsense is going on, they increase their chances of death by taking riskier modes of transportation. And, all of the exposure data is based on a properly calibrated machine, delivering a specific dose - something only an idiot would trust, given the trained monkeys who run the things.

But go on believing what you wish, leaving us paranoid and ignorant folks as the only ones doubting the TSA's glowing credentials and expertise.
