TSA Scanner Levels 10x Higher Than Expected?

I recently posted about mistakes made in radiation testing reports. Since then, I’ve seen a lot of chatter on the web about how our advanced imaging technology (AIT) backscatter machines were operating at higher levels. While there were errors in the reporting, please rest assured that our body scanners were still screening well below national standards.

For those of you who like to get into the weeds, the “10x higher” issue stems from a field on the survey form that was not divided by 10 as the survey specified. So, the amount was incorrectly reported as 10x higher than it was supposed to be, not 10x higher than the requirement. So, how did we know the number in the third example was inaccurate? That’s an easy one. The machines are incapable of operating at those levels. They’re designed that way… Like the protection a circuit breaker provides to a home, the AIT machines contain safety systems that prevent the production of radiation levels in excess of federally established limits.

You can read the post I mentioned above about how we’re going to retest all of the machinery and post the results on a special section of our web page.
