Can a metal detector see through your body?

I always have people asking me if walk through metal detectors are able to see all the way through a persons body. Well the simple answer to the question is yes they absolutely can!

Some people believe that if you swallow a metal item or have a metal screw or plate in your body the metal detectors won’t pick it up. This is a false notion.

Most metal detector work with a magnetic field that shoots pulses from one side of the detector to the other side. The electromagnetic field for the most part is only effected by metal objects. This is why an airport metal detector can see metal inside the body – the body is obviously not metal so the electromagnetic field doesn’t have a problem penetrating through the flesh.

That being said have no worries as far as health goes. Your standard T.V and computer monitor runs on a higher frequency than these metal detectors do.
