I don't know if that makes it any more plausible, but this is the argument
they use if you ask for having your ISO 3200 film hand checked. Since
modern X-ray scanners use pulsed radiation, it could very well be that the
total dose of a scan is extremely low even if a single pulse has much
higher intensity than any background radiation.
