4.10.12 How Does Radio-Wave Propagation Affect An RF Exposure Assessment?

An exposure assessment must account for more than transmitter power and straight-line distance. This FAQ explains how antenna gain and direction, field region, reflections, diffraction, scattering, terrain, buildings, and nearby conductive structures can change electric field, magnetic field, and power density at accessible locations, and why measurements may be needed when simple far-field models are insufficient.
