Electric Research & Management, Inc. (ERM) performed a survey to quantify the levels of extremely low frequency (ELF, 3-3000 Hz) electric and magnetic fields (EMF) and radio-frequency (RF, 300 kHz to 50 GHz) electric fields near electric facilities along Amtrak's Northeast Corridor (NEC) between New Haven, Connecticut, and Boston, Massachusetts. This work was sponsored by the Federal Railroad Administration (FRA) and contracted to ERM with oversight by the Volpe National Transportation Systems Center.
