I. ANSI/IEEE 1992 Maximum Permissible Exposure (MPE) for Controlled Environments

  • *

    Plane-wave equivalent power density; not appropriate for near-field conditions, but sometimes used for

comparison purposes. f = frequency in megahertz (MHz) V/m = volts per meter A/m = amperes per meter mW/cm2 = milliwatts per centimeter squared
