Walk-through metal detectors use a low-level electromagnetic field to detect the presence of metal on a person’s body or belongings. The electromagnetic field is generated by a coil of wire inside the metal detector, and is not harmful to human health.
The levels of electromagnetic radiation emitted by walk-through metal detectors are well below the limits established by international safety standards. These standards are designed to protect against any potential health effects from exposure to electromagnetic fields.
There is no scientific evidence to suggest that walk-through metal detectors pose any risk to human health. In fact, the levels of electromagnetic radiation emitted by these devices are much lower than the levels of electromagnetic radiation that are naturally present in the environment.
It is important to note that walk-through metal detectors may trigger alarms if a person is carrying certain medical devices, such as pacemakers or insulin pumps. These devices may contain metal components that can set off the metal detector. If you have a medical device that may trigger a metal detector, it is important to inform the security personnel at the checkpoint so that they can take appropriate measures to screen you.
