Science has shown that in all consumer electronics
applying varying degrees
generates electromagnetic waves of different frequencies. Electronic emission has
become a new environmental disaster of global scale.
Question. How to influence the electromagnetic field of overhead power lines to
people, animals and plants?
Answer: ______________.
Task 15: Hertzian waves
Sources of artificial electromagnetic radiations, which
include aerial power lines
of high and super-high voltage, technical equipment of broadcasting, television,
microwave and satellite communication, radar and navigation systems, laser
beacons,
household appliances - Wi-Fi, microwave ovens, monitors, and others.
Significantly affected on natural electromagnetic background.
In large areas, especially in the vicinity of passage of the overhead power lines
of high and super-high voltage, radio and TV centers, radar installations, electric and
magnetic fields has increased from two to five orders of magnitude, creating a real
threat to people, flora and fauna.
Sanitary limiting dose of the electric field is 1 volt per meter. The high-voltage
power lines exceeding this dose observed at distances of up to a dozen, sometimes up
to hundreds of meters.
Surveys indicated that standing under a power line for 15
minutes three times a
day for six days cause of neurological changes, decreased brain health. In areas where
there are high-voltage power lines, electrostatic field strength can be up to several
thousand volts for 1 m.
The influence on the human body of high frequency electromagnetic waves
(from 3 kHz to 300 GHz) of radio and television dependent from its frequency. The
higher frequency or the shorter wavelength, the greater the impact.
High-frequency ultrasound, high-intensity laser beams very strong influence on
the human brain. If they are not used for peaceful purposes, the impact of
psychotropic weapons can change the cerebration: deteriorating memory, disturbed
coordination of movements, appears an inadequate response to what is happening
around.
Question: What everyone should know in order to no harm to health?
