Can Titanium set off a metal detector?
Titanium does not start most metal detectors The metal detectors used by TSA create an electromagnetic field, which reacts with magnetic metals and activates an alarm. … Titanium is non-magnetic, so it rarely sets off standard metal detectors.
Can you have a pet scan if you have metal in your body?
