In the test report, released to the public by the FDA, and is on the web, 
the OPERATIONAL KVp is cited as 50KV. The mAs has been REDUCTED.

I do not wish to editorialize right now. But I'm sure that anybody who knows 
that Mammography machines operate at 27KVp, 100mAs, will realize what is 
going on here.

Bottom line, NEVER get close to those frying, sorry, 'scanning' machines!

(If you need the web address, for downloading the (pdf) test report, just 
let me know and I'll ferret it out for you.)

Does anyone know the average keV used for the screening? I've been in the 
Middle East and am catching up on the latest TSA re-evaluation, and whether 
the survey meter used to perform the measurements is actually adequate. 
There have been questions raised whether or not the N43.17 standard is being 
met with the smaller ion chamber used for the measurement compared to what 
the standard states, I.e., 1500 cc detector.

Any information would be appreciated.
