The word “electrosmog” is an artificial term coined in the 70s. The “smog” part is
a compound of the two English words “smoke” and “fog”. Thus, “smog” is roug-
hly equivalent to “dirt”. Finally, “electrosmog” could alternatively be described as
“electric dirt”.
In contrast to “normal” smog which is, year after year, easily noticeable in the
cities with our eyes and nose, “electrosmog” is not detectable with our sense
organs. Thus, we can only measure and evaluate “electrosmog” using dedicated
“electrosmog measurement devices”.
Commonly, electrosmog is divided into two types:
low-frequency
electrosmog
(e.g. traction power, mains cables,
high-voltage lines etc.)
high-frequency
electrosmog
(e.g. cellphones, cell towers, satellites, radar,
radio and TV broadcast, CB radio etc.)
With our RF (HF-) SPECTRANs, you can only measure high-frequency elec-
trosmog. For measuring low-frequency electrosmog, you
additionally
need one
of our
LF
(NF-) SPECTRAN models.
The electrosmog itself consists of
electric
and
magnetic
fields:
Electric fields
These fields result from a voltage between two poles. The nearer these poles
are to each other and the higher the voltage, the stronger the electric fields for-
med between them. Thus, electric fields are present even when no current is flo-
wing, meaning that even though your lamp, TV etc. might be turned off, its elec-
trical field is still present at full power! Every cable (especially those hidden
behind walls) is a potential source. Electric fields can be easily screened using
conductive materials. Thus, you should, if possible, replace ALL cables with our
screened versions (see attached brochure and price list).
Alternating magnetic fields
These fields form when current flows through a conductor. The higher the cur-
rent and the wider the conductors are placed to each other, the stronger the
magnetic field. The only way to effectively screen against magnetic fields is the
utilization of Aaronia
Magno-Shield
foil or panels.
High-frequency fields
As electric and magnetic fields do not form separately anymore at higher fre-
quencies, they are mostly measured as the sum of both field types, expressed
as power flux density (
W/m²
or
V/m
).
