Abstract

Provides specifications for preferred methods for measuring and computing external radio frequency electromagnetic fields to which persons may be exposed. Specifies preferred methods for the measurement and computation of the resulting fields and currents that are induced in bodies of humans exposed to these fields over the frequency range of 100 kHz - 300 GHz.
