This study aims to evaluate the safety of electromagnetic exposure of passers-by (adults and children) in the electromagnetic environment of walk-through metal detectors operating at 6.48 kHz. The magnetic induction intensity and induced electric field intensity in a human model were calculated using COMSOL simulation software to simulate the operating environment of the electromagnetic walk-through metal detectors and compared with the International Commission on Non-Ionizing Radiation Protection (ICNIRP) public exposure limits of 27 μT and 874.8 mV/m. The magnetic induction intensity was the highest in the human body when directly below the walk-through metal detectors near the coil side. This intensity was observed on the arm near the door panel 2.44 μT (adults) and 1.86 μT (children), corresponding to 9.04% and 6.89% of the ICNIRP limit (27 μT), respectively. The electric field intensity in the CNS tissue was the highest in the human body when inside the walk-through metal dectors, distributed over the scalp and skull near the coil side, 1.27 mV/m (adults) and 1.1 mV/m (children), corresponding 0.15% and 0.13% of the ICNIRP limit (874.8 mV/m), respectively. The simulation values were below the public exposure limits set by ICNIRP, indicating that the electromagnetic fields generated by the transmitting coils during the operation of the walk-through metal detectors do not pose a health risk to humans owing to electromagnetic exposure.
