| Título | Electromagnetic field (EMF) strength inside underground railway trains |
| Resumo | The electromagnetic field (EMF) environment surrounding underground railway trains is among those most frequently met by the general public in daily life. When an underground railway train passes through a tunnel, especially, passengers are exposed to the EMF radiated by several repeaters installed on the wall. EMF sources are close to passengers under these conditions. Supplement 19 to ITU-T K‑series Recommendations reports evaluations of EMF exposure levels in underground railway trains from mobile communication base stations installed in tunnels. |
