1.5. Maximum RF Power Density Limits
The RF Radiation Power Density limit figure recommended by Vislink is
based upon guideline levels published in:
a. IEEE standard C95.1 1999 - IEEE Standard for Safety Levels with respect to
Human Exposure to Radio Frequency Electromagnetic Fields, 3 kHz to 300 GHz.
b. Guidelines for Limiting Exposure to Time-varying Electric, Magnetic &
Electromagnetic Fields (up to 300 GHz) published in 1998 by the Secretariat of
the International Commission on Non-Ionising Radiation Protection (ICNIRP).
Both documents define guideline RF power density limits for "Controlled"
and "Uncontrolled" environments. An uncontrolled environment is defined
as one in which the person subjected to the RF radiation may be unaware
of and has no control over the radiation energy received. The
uncontrolled environment conditions can arise, even in the best regulated
operations and for this reason the limits defined for the uncontrolled
environment have been assumed for the Vislink recommended limit.
Documents a) and b) also show the RF power density guidelines to be
frequency dependent. Different power density / frequency characteristics
are presented in the two documents. To avoid complexity and to avoid
areas of uncertainty, Vislink recommends the use of a single power
density limit across the frequency range 100 kHz to 300 GHz. The 1w/m²
power density limit we recommend satisfies the most stringent of the
guidelines published to date.
