What if I had a sheet of lead, or some lead foil?
Might stop x-ray I would think.
Magnetic would still detect the ferrous?
And would a big black square trigger the AI curiosity for a manual search?
It is really hard to smuggle peanut butter these days. Good thing it is not Pizza.
The lead would show up as a “blank” space, in turn arousing suspicion because of it’s inability to be scanned. Trust me, it’s been tried.

I carried a calibration instrument through TSA that is used to calibrate the air pressure and the force applied by dynamite drills. The nitrate traces set off the explosives alarm and the big lead-acid gel battery appeared as an opaque rectangle in the X-ray. I most surely was singled out for a closer look. After telling them what it was and how it is used, I just had to show them the screen light up and display a working menu. They declined my offer to open the front panel.
