Man-made EMFS are harmful
Environmental man-made EMFS
Man-Made EMFs occur in
the transmission of information and electrical power in many industrial processes,
electronic equipment and domestic appliances.
Man-made electromagnetic fields are generally divided into
two groups according to their frequency level:
Extra low frequency (ELF)
Extremely-Low Frequency (ELF) Range.
According to generally accepted usage, the ELF region
is from ~3 Hz to 300 Hz. ELF EMFs are produced by alternating
current flowing in power grids:
50Hz in Europe
60Hz. In the U.S.
ELF fields
are produced in power lines, electrical wiring, and electrical equipment.
E.g.high power transmission lines, transformers, computers, monitors,
fluorescent lights, televisions, hair dryers, and digital alarm clocks.
Many pulsed electromagnetic field (PEMF)
therapy devices also use ELF frequencies.
Whether they are beneficial or not depends on the actual frequency being utilized.
Some ELF frequencies are naturally used by our body to maintain health. E.g. the
brain operates on different ELF ranges throughout the day called alpha, beta, alpha,
theta and delta waves.
EMF penetration of earth and oceans increases as
frequency decreases. At 5MHz the penetration is
about 0.12 m. However, at 5Hz, the penetration is 112m. Thus, ELF/ULF EMF waves
(5-50Hz) penetrate deep into the earth and oceans, and are used for submarine
communications (U.S. 77 Hz, Russia 83 Hz).
ELFs are not necessarily harmless and may be "Wolves
in Sheep's Clothing". Since
these widespread EMF frequencies are so low and do not demonstrate any dramatic
thermal or ionizing effects (as produced by nuclear devices), there has been a commonly
held fallacy that they must therefore be harmless, however:
ELFs do induce weak, but significant, electric currents in conducting objects,
including people and animals .
Certain frequency bands between 15 - 60 Hz have been found to promote cancers.
Frequencies in this range have been found to alter cell protein
synthesis, mRNA functions, immune responses and intercellular communication [Adey,
1992].
Electropollution may cause us to feel more stressed, fatigued and "out of
balance". More than a thousand scientific
papers are published each year, defining the effects of our abnormal electromagnetic
environment. Epidemiological and laboratory studies indicate that any abnormal frequencies
produce increased health risks.
