Does the general security door have radiation?

Civil aviation security doors and metal detectors use human metal detectors. Its principle is the same as that of military mine detectors. The current in the instrument forms a magnetic current. Once you have a metal substance, it will beep, and it will not produce radiation, which is not enough to cause radiation damage to human body and fetus. Therefore, expectant mothers can rest assured that the general security inspection will not affect the baby!

The security X-ray machine really radiates a lot, so there are lead curtains at both ends of the machine to prevent X-rays from leaking out. When the bag is put into or taken out of the X-ray machine, part of the lead curtain will open, so some X-rays will leak out. Therefore, it is suggested that expectant mothers should not put any part of their bodies in the machine during security inspection, but there is no problem outside the machine. Expectant mothers who accept subway security check should put their bags in or out of the X-ray machine, so please try to stay away from the machine.
