Just another thought, FT who still must fly for a living out of necessity and even those who don't fly that often might want to "invest" in a pocket-sized dosimeter badge as one approach the TSA checkpoints for one's own self protection & exposure monitoring. ^
If those equipment with biomed applications start to malfunction and nobody at TSA/OSHA is checking/monitoring/certifying/inspecting them on a schedule, regular basis - you could be subject to exposure at a greater distance and at a higher dosage than we've being told - it could leak or generate a substantially higher dose.

At my workplace, all radiation equipments along with other medical equipments are tested, checked and calibrated on a regular basis, it's mandatory and some of them on a daily basis ....
There's no law against traveling with one, and if a growing body of FT starting wearing them & using them at the airports & other checkpoints where the machines are running, it will definitely raise the awareness level and be a talking point among other novice travelers and even among airline crews.
I wouldn't be surprised if some of them already brought one at their own personal expenses and start using/wearing them discretly under their blue uniform.
