CT scanners? Can I get a lead apron to wear in the screening area please?

  They're shielded. And the current machines also use X-rays; there's no change to the kind of radiation used.

    But the direction changes. Current machines aim downward. The new ones will spin, and fire in all directions. And there is more radiation in total since now there's there are multiple images, while before it was just a single one per bag. I'd also be concerned about backscatter going out the sides, since there is more radiation in total. All that said, the shielding should take care of it.

  Try asking them why they're not wearing dosimeters. They get really defensive!

    This CDC study[0] looked into that question, the answer was inconclusive (with some workers receiving a higher annual dose than is allowed, while most received a safe dosage). The problem seems to be malfunctioning scanners. [0] https://www.cdc.gov/niosh/hhe/reports/pdfs/2003-0206-3067.pdf https://www.cdc.gov/niosh/hhe/reports/pdfs/2003-0206-3067.pd...

      Isn’t that what dosimeters are supposed to help detect?
      • Someone1234 8y ago
        That's what was inconclusive. > Given the strengths and weaknesses of this study, the need for a routine radiation dosimetry program for TSA screeners can neither be justified nor refuted at this time. I assumed above that people would read the link before responding.

      Sounds like a good reason to wear dosimeters
