>> 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..."
