My wife set off a gamma detector in the Shanghai/Pudong airport--heart scan. Fortunately, their security isn't insane, it was resolved actually too easily for my taste. (No effort was made to determine if she was hot as opposed to carrying something hot.) Here they have simply thrown people in prison when the radiation detector went off--100% of who were hot for medical reasons. Notably, we had passed through two US airports at 4x and 8x the radioactivity, didn't set off any alarms. Either there weren't detectors, or they were capable of filtering out alarms at that energy level (Tc-99m isn't useful for a bad guy, a detection is always medical.) I find the latter very unlikely when scanning a large area.
