For different frequency ranges, the recommended limits for unperturbed field strength and equivalent plane-wave power density are then adjusted for the different absorption characteristics of the human body. In the lower frequency ranges, further reductions in field strengths might be recommended to reduce the danger of RF burns from direct contact with metal objects.

In both tables, the guidelines are presented to represent frequencies as close as possible to those used by the GWEN system. The electric and magnetic fields induced in the human body by low-frequency and ultra-high-frequency radiation from the GWEN transmitters at locations outside the perimeter fence (see Chapter 3)
