RF Exposure Assessment
Introduction
Any Radio Equipment is emitting Radio Frequency (RF) Radiation through its antenna which may be integrated
to the equipment or not. It is important to follow any local, national or international regulation during installation
and operation of the Radio Equipment to avoid radiation hazards.
Regulations
A lot of countries have issued and follow their own regulations but others adopted European or international
regulations, standards or guidelines.
In Europe, some countries follow the recommendations included in 1999/519/EC directive which is based on
the guidelines document published by the International Commission on Non-Ionizing Radiation Protection
(ICNIRP). Other countries have issued their own regulations for this purpose.
The above mentioned European Directive provides the reference levels (limits) for assessment of the human
exposure to electromagnetic fields based on health effects. European Union, FCC (US) and Industry Canada
Reference Levels for microwave frequencies applied to INTRACOM Telecom equipment are given in the
following table (Table 1).

RF Exposure General Guidelines for equipment installation
As a general rule it is expected that the highest level of emission would be in line of sight and in close vicinity
of the antenna. Additional requirements for the installation of equipment shall be as follows:
The equipment should be located in such a way to prevent the public from accessing the area where the
RF Radiation exceeds the regulation limits. For this, a compliance boundary is determined, based on its
radio characteristics. Outside this area the RF radiation levels are below the reference levels (limits).
Operation and maintenance personnel, which have to work within the RF radiation compliance boundary
area, should be informed about the source of radiation and should have the capability to power off the
radio equipment before entering the compliance boundary area.
The compliance boundary area should be defined by a relevant warning sign or physical barrier.
