Electromagnetic fields (EMF)

 

The potential health risks to passengers and the environment from electromagnetic fields (EMF) generated by the operation of electrically powered high-speed transportation systems have been recognized as an important issue for many years, since magnetic properties can potentially induce physiological effects in body tissues. For scientific evaluation, the calculated and experimental values of electromagnetic fields in high-speed steel-wheel-rail systems such as ICE, TGV, and Shinkansen should be compared with the two high-speed maglev systems, Germany's Transrapid and Japan's Superconducting Maglev (SC Maglev), based on available data. To estimate the effects on passengers, the field values generated by the power supply system and the propulsion and suspension systems need to be examined. For further comparison, the peak values of the electromagnetic fields should be considered.

The study of electromagnetic fields (EMF) generated during the operation of high-speed transportation systems shows that the electric fields associated with maglev technologies do not pose a health risk to passengers according to international standards.

If the fields inside the vehicle are considered, the EMS system (Transrapid) appears to be even more favorable than the EDS system, which requires strong shielding. Overall, both maglev systems appear to be clearly superior to conventional wheel-rail trains in terms of EMF exposure.

The EMF exposure for passengers in conventional high-speed trains is significantly higher than for users of high-speed maglev systems. In terms of EMF emissions, maglev systems can be considered as clearly superior to conventional wheel-rail trains.
