4. RF Exposure Limits
4.1 Uncontrolled Environment
Uncontrolled Environments are defined as locations where there is the exposure of individuals who have no knowledge or
control of their exposure. The general population/uncontrolled exposure limits are applicable to situations in which the
general public may be exposed or in which persons who are exposed as a consequence of their employment may not be
made fully aware of the potential for exposure or cannot exercise control over their exposure. Members of the general
public would come under this category when exposure is not employment-related; for example, in the case of a wireless
transmitter that exposes persons in its vicinity.
4.2 Controlled Environment
Controlled Environments are defined as locations where there is exposure that may be incurred by persons who are
aware of the potential for exposure, (i.e. as a result of employment or occupation). In general, occupational/controlled
exposure limits are applicable to situations in which persons are exposed as a consequence of their employment, who
have been made fully aware of the potential for exposure and can exercise control over their exposure. The exposure
category is also applicable when the exposure is of a transient nature due to incidental passage through a location where
the exposure levels may be higher than the general population/uncontrolled limits, but the exposed person is fully aware
of the potential for exposure and can exercise control over his or her exposure by leaving the area or by some other
appropriate means.
