I used to work at a dental office. A dentist xray machine wouldn't see anything behind amalgam (metal) fillings. Also the old fashion xray machines were more poweful. The newer digital xray machines ones use a lot less radiation but are more sensitive. Still they can't see past metals either. Unless it was really thin. I have no idea if airport or xray machines are more powerful, but I've never seen an xray see through a coins.
I might not trust thin aluminum foil, but a sheet metal box or pipe would be really tricky.
