Electrosmog:
a hotly-debated term
Among the various neologisms commonly used in Italy these days, we find the word
eletcrosmog. It stands
for electromagnetic "pollution" or presence of
electromagnetic fields
due to the current uses of electric
energy.
The
word recalls other types of environmental pollutions involving "smoke and fog" (smog),
even though in this case there is neither smoke nor fog.
Electric
and magnetic fields are always present in the space around electric currents. They propagate
even without
conductors, in fact, they diffuse best in vacuum.
If
electric currents oscillate, also their respective electromagnetic fields assume
oscillatory patterns with
sinusoidal waves characteristics, also known as
electromagnetic waves or radiations (identified by
wave length and
frequency).
By modulating the physical magnitudes of
these waves it is possible to create special signals, which, in vacuum, travel
at the speed of light and allow us to communicate at great distances. This explains
the recent proliferation of numerous means and appliances based on such
telecommunication systems.
There is an unceasing proliferation of technology connected to electricity, providing
enormous advantages in many fields of human life. However, these advantages are often undermined
by the visual impact on the environment of power lines and by panic stories about possible
health risks. In this regard, the data has not yet been scientifically confirmed and its acceptability has not really been evaluated.
People are scared by this
information, they are not able to
reach a "balanced judgement", and even less, an "agreement" , as the problem is often complicated by the fact
that the relative risks do not affect directly the same people who receive the benefits.
It is to be hoped that more accurate information will make people see that everything has
its price and that the choices must be made by comparing "cost" and
"usefulness"; that is to say, we must evaluate the overall risks and benefits.
