[ RadSafe ] TSA Scanner is Health Risk

[blhamrick at aol.com]

There are documents available on the web covering various assessments made, the instrumentation used, etc.  See, e.g., http://www.tsa.gov/assets/pdf/jh_apl_v1.pdf, which is the assessment of the Rapiscan Secure 1000 by Johns Hopkins University Applied Physics Laboratory.

Subject: [ RadSafe ] TSA Scanner is Health Risk

Dear Mr. Perle,

Do you happen to know if there are ANY measuremnts results
using TLD monitors or film badge monitors to inform us with scientifically 
derived results about the radiation exposure / absorption levels of airport 
x-ray scanners to passengers?

In the absence of such rudimentary measurements, nobody in this forum has 
the grounds to "approve" or "disprove" these machines.

With the obvious track record of the FDA, I would caution, though, any 
passenger, to avoid ANY x-ray exposure!

The scanners operate at 50 KvP (!)
Here is an example of reincarnation: Xeromammography, that has been quite 
dead for the past 40 years, is gaining a tremendous and profitable revival, 
in the transmogrifyed "X-Ray Back Scatter Scanner..."

Regards,
