human environment”.
The following dates are fixed:
• latest date by which this document has to be 2022– 2022–04–26
implemented at national level by publication of 04–26
an identical national standard or by
endorsement
• latest date by which the national standards (dow) 2024–04–26

— consideration of the new Directive 2013/35 /EU related to workers exposure;
— update of referenced standards;
— provision of a method to determine the relevant domain.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CENELEC shall not be held responsible for identifying any or all such patent rights.
1 Scope
This document specifies the method for assessing overall exposure from all fixed radio frequency
sources at a broadcast site. This assessment can be applied at any time but is carried out when the
exposure situation changes in or around the aforementioned site.
This document can play an essential role in the coordination of different stakeholders, with respect to
ensuring EMF exposure compliance in the vicinity of a broadcast site especially for equipment installed
within the site.
2 Normative references
The following documents are referred to in the text in such a way that some or all of their content
constitutes requirements of this document. For dated references, only the edition cited applies. For
undated references, the latest edition of the referenced document (including any amendments) applies.

broadcast site

magnetic and electromagnetic fields (0 Hz - 300 GHz)

public to electromagnetic fields (0 Hz to 300 GHz), Official Journal, L199, of 1999-7-30, p.59-70
3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
ISO and IEC maintain terminological databases for use in standardization at the following addresses:
— IEC Electropedia: available at
— ISO Online browsing platform: available at
3.1
basic restriction
restriction on exposure to static and time-varying electric, magnetic, and electromagnetic fields that is
based directly on established health effects
3.2
broadcasting service
radiocommunication service in which the transmissions are intended for direct reception by the general
public
Note 1 to entry: This service may include sound transmissions, television transmissions or other types of
transmission.
3.3
broadcast site
site where one or more broadcast transmitters are operated
3.4
controlled area
area where access is controlled by the operator and is not accessible to the public
3.5
exposure ratio
ER
for an individual source, between 100 kHz to 10 GHz:
EH
ER= MAX , ;
EL HL
between 10 MHz and 300 GHz:
Seq
ER=
SL
where
ER is the exposure ratio at frequency f of the source;
EL is the E-field reference level at frequency f;
HL is the H-field reference level at frequency f;
E is the assessed E-field at frequency f for the source;
H is the assessed H-field at frequency f for the source;
SL is the Equivalent plane wave power density reference level at frequency f;
Seq is the assessed Equivalent plane wave power density at frequency f for the source
Note 1 to entry: Assessed means measured, calculated or simulated.
3.6
reference level
provided for the purpose of comparison with values of measured quantities and respect
of recommended levels will ensure respect of basic restrictions
Note 1 to entry: If measured values are higher than reference levels, it does not necessarily follow that the basic
restrictions have been exceeded, but a more detailed analysis is necessary to assess compliance with the basic
restrictions.
Note 2 to entry: In the frequency range from 100 kHz to 10 GHz, the physical quantity used is electric field strength,
and magnetic field strength. In the frequency range from 10 MHz to 300 GHz, the equivalent plane wave power
density can also be used.

3.9
relevant source
principle of relevance establishes the conditions under which a radio source is considered relevant such
that account is taken of the contribution of that source when assessing RF exposure at an assessed
location
Note 1 to entry: In the absence of a national or local definition, the relevant source is a fixed radio source, in the
frequency range 100 kHz to 300 GHz, which has an exposure ratio of more than 0,05 at an assessed location.

party controlling access to the controlled area
3.11

threshold distance
TD
minimum vertical or horizontal distance in a given direction, from the antenna, at which compliance with
reference levels which, in the absence of national or local definition, are established by Council
Recommendation 1999/519/EC, is achieved at all heights when considering emissions from the site
alone
3.13
total exposure ratio
TER
sum of exposure ratios:
TER= ER
