“…They concluded that being exposed to low-frequency magnetic field in a carriage will not cause harm to passengers [7]. Yang and Lu studied the electromagnetic exposure of railway pantograph arcs to railway ground workers and concluded that the electromagnetic radiation generated by pantograph arcs does not affect the health of railway workers when raising and lowering pantographs [8].…”

With the advent of modern, high-speed electrified rail systems, there has been increasing concern about electromagnetic safety in rail carriages. The aim of this study was to assess the electromagnetic safety of passengers on trains by utilizing advanced 3D electromagnetic simulation software. A comprehensive model of the electromagnetic environment experienced by passengers on a CR400AF train, specifically under the influence of catenary radiation, was constructed. We analyzed the magnetic field strength, electric field strength, and current density in the brains of 20 passengers in various positions in the train. The findings revealed that among the 20 passengers analyzed, the maximum and minimum magnetic induction intensity recorded in the brain were 8.41 and 0.01 μT, respectively. The maximum and minimum induced electric field intensities were 1110 and 10 μV/m, respectively. Lastly, the maximum and minimum induced current densities were 1200 and 10 μA/m2, respectively. The results show that when people ride on the CR400AF train, the magnetic induction intensity, induced electric field strength, and induced current density in the brain are below the recommended basic limits of exposure to power frequency electromagnetic fields in the guidelines of the International Committee on Non-Ionizing Radiation Protection. The power frequency magnetic field generated by the catenary can be effectively shielded by the aluminum alloy car body. The final result of this study indicates that the electromagnetic exposure from the contact wire at the level 25 kV does not pose a threat to the health of passengers on the CR400AF train.

“…The results of these studies showed comparatively high exposure from civil communication bands and the major source of exposure in the subway was GSM900. Most previous studies focused on the coverage of the wireless system in subways or a high-speed railway environment [24], and little information has been published on electromagnetic exposure safety in the rail transit system, except for recent studies [8,25,26]. The research on the general public electromagnetic exposure of subway passengers, especially children, is limited.…”

The objective of this work is to evaluate the safety of adult and child passengers exposed to a radio frequency (RF) source, i.e., a leaky coaxial cable (LCX) on the subway platform. An adult model, a child model, and a LCX model have been numerically designed in COMSOL Multiphysics software. The distributions of the induced electric field (E-field), specific absorption rate (SAR), magnetic field (H-field) and the head temperature increase in adult and child passenger models were calculated at 900 MHz. The induced fields in the passengers were compared with that without screen doors. The results show that the E-field, SAR and H-field in the whole body of the child are 2.00×10 −2 V/m, 1.07×10 −7 W/kg, and 2.94 × 10 −4 A/m, respectively. The E-field, SAR and H-field in the central nervous system of the child are 1.00 × 10 −2 V/m, 2.44 × 10 −8 W/kg, and 2.41 × 10 −4 A/m, respectively. The maximum values of the E-field, SAR and H-field in the adult passenger are 1.49-2.34 times higher than those of the child. The E-field, SAR, and H-field in the passenger models without a screen door are larger than those with a screen door. The screen door has a partial shielding effect on the RF electromagnetic field. The values of the maximum temperature that increases in adult and child head tissue are 0.2114 and 0.2111 • C after waiting 6 minutes exposure, respectively. All calculated results are well below the International Commission on Non-Ionizing Radiation Protection (ICNIRP) limits for general public exposure, indicating that RF electromagnetic exposure caused by the LCX on the subway platform is not a threat to passenger's health.
