DECT Phones and Wi-Fi
Networks pose a significant health risk, especially to children
"DECT (Digitally Enhanced Cordless Technology) has been incorporated into many new cordless phones (and some models of baby monitors) by manufacturers such as Panasonic, GE, Motorola and V-Tech. These phones have become very popular in the last few years because they are very powerful providing clearer reception. If you've purchased a new 2.4 GHz or 5.8
GHz cordless phone recently you may very well own a phone that uses new high-powered DECT technology. DECT technology is "always on" and produce a very strong radiation field, similar to that of a cell phone tower,
even when not in use and just sitting idle in the cradle.
Constant exposure to this high frequency radiation will lead
to much ill health and increases in contributing to the rise
in electrosenitivities we are currently seeing in North
America " says Kevin
Byrne, President, EMF
Solutions.
In December 2005 The Health Ministry in Salzburg, Austria issued a Health warning concerning DECT phones and Wi-Fi (wireless networks) and urged they not be used in Schools and Kindergartens.
Read the letter from the Health Minister in Salzburg, Austria: "The official advice ... is not to use WLAN and DECT in Schools or Kindergartens."

July 18th 2009: Israeli
government bans marketing wi-fi home devices as a
precautionary measure
By Aviv Lavie
The communication and
environment ministries have banned the cellular companies
from marketing
phones in the house and internet connection that are based
on cellular modem, because of the radiation concern.
The cellular companies will have
to conceal the plans to become an important factor in the
field of communication in the house The communication
ministry executive and the environmental ministry executive
summarized that the companies will receive an order to stop
marketing the wired phones and the internet connection that
are based on cellular wireless modem.
Cellcom, which led the new field,
already removed from its website the advertisements for
these products. The companies Bezeq and other companies that
operate house services that are based on wired communication
are the big profit makers from this.
The story began 3 months ago,
when the head of radiation arm in the environment ministry,
Dr. Stelian Galberg, watched an advertisement for house
communication systems of the cellular companies, that
started being sold without anyone informing him. Galberg was
afraid that if these systems succeed in penetrating, there
would be a need to erect thousands of new antennas in order
to enable them operate and the radiation quantity will
increase a lot. The reason for that is that in the house the
system operate as a wired line like Bezeq systems but
outside the house they receive the communication from the
cellular antenna.
In the Environment ministry
[they] approached to the communication ministry, and claimed
that the law of non ionizing radiation enforces to act
according to the precautionary principle, meaning expose a
person to radiation only when it’s justified. “When a
person travels in his car and wants to talk on the phone he
has no choice but do it with antennas”, Galberg told to
Business, “but when we are talking on the phone in the
house, it can be done with wired communication” The
radiation levels will increase significantly
In the first stages, the
communication ministry did not take a stand and enabled the
cellular companies widen the marketing of the home systems,
but in a meeting between the two executives of the
ministries, the representatives of the communication
ministry admitted that the only justification for the
service is the technological neutrality principle, according
to which, the communication ministry will offer to the
public many technologies and they will choose according to
their will the most suitable service.
In contrast, the environment
ministry team clarified that the service will increase
significantly the radiation levels to which the public is
exposed “with no justification”. In view of these
things, it was agreed to order the cellular companies to
stop immediately the marketing of home systems
“The law forces us to act
according to the precautionary principle” Galberg said
yesterday. “When we transfer the guideline to the cellular
companies, if some company will continue to market wired
systems it will be against the law. We will enable them do
it only where there is no wired communiation like in
isolated houses that are disconnected to Bezeq lines.”
The question is what lessons will
be learnt of this development. Dr Galberg said “we
discussed the lessons and the first thing we told them is
‘next time ask us first’. They didn’t receive it with
love, but definitely with understanding”. The cellular
companies said that “the subject is being examined”. The
minister of environment said that “the health
consideration is before any economic ” consideration, and
we have no intention to compromise on this subject.
September, 2007: German Gov't warns citizens to avoid using Wi-Fi In Germany the Federal Government's Agency for Radiation Protection issued a Health warning concerning DECT phones: Press Release, 31 January 2006 German Federal Agency For Radiation Protection (Bundesamt für Strahlenschutz -
BfS) DECT - The Radiation Source at Home: Cordless Phones radiate unnecessarily
A cordless phone of DECT standard is often the strongest source of high frequency electromagnetic radiation in a private home. To renounce your cordless phone as a precautionary measure will contribute to minimise your personal radiation exposure. "However, it would be possible for the industry to develop DECT phones which could address the issues of precaution and radiation protection better than the current devices" said Rüdiger Matthes, expert of the Bundesamt für Strahlenschutz (Federal Radiation Protection Agency)
Cordless landline telephones of DECT standard have no output control to regulate power output according to the actual power needed. Therefore, the base station and the handset are permanently emitting radiation at the same power level during a call, no matter whether the user holding the handset is one meter or 300 meters away from the base station.
Matthes: "Therefore, we demand that cordless phones should be developed to include a feature of power output control, so that the power output during a call would be adapted to the distance of the handset from the base station, using only the level of power necessary to keep the communication going."
To secure smooth operation, the base station also continually sends a control signal to the handsets, including when the phone is not in use. According to the BfS, cordless telephones should be devised so that they are emission free on stand by mode. "Luckily, there is a new generation of devices which fulfil just this requirement, and thus help to lower the radiation load in the home." declared Matthes.
To prevent possible health risks, the BfS recommends minimising personal radiation exposure. The following tips will help you if you are not prepared to completely give up the benefits of a cordless phone: Put the base station in a place where you do not spend much time, for example in the hall. Do not put it directly on your desk. Only make short phone calls. Use the latest generation of phones which are emission free when the handset in connected to the base station.

and Electromagnetic fields

We
are constantly being misled by elements of the mobile phone
and electronics industries (who have huge vested interests
in the infrastructure) into believing that the pulsed
microwaves used in cell phones and Wifi are harmless. Their
sole justification for this is that the radiation is too
weak to generate significant heat when they are absorbed by
living tissues.
However,
they are seemingly oblivious to the fact that living cells
depend on electricity and electrically charged atoms and
molecules (ions) to maintain their healthy functioning. They
can therefore be damaged electrically by electromagnetic
radiation that is far too weak to generate significant heat.
For
example, our cells use the energy from food to pump ions out
of mitochondria (the cells’ power stations). They
are then let back in through an ATPase (an enzyme not unlike
a molecular water wheel). Each turn of the wheel generates a
molecule of ATP, which is the main energy currency of the
cell. In effect, an electric current flowing into and out of
these tiny structures provides virtually all of our bodily
energy.
Some
of this ATP is then used to pump ions out of the cell. When
they return via special enzymes (called transporters) in the
cell membrane, they can carry with them essential nutrients
that the cell needs to absorb. So we use electricity to
absorb our food too.
Another
example is in our nerve and brain cells. They use ATP to
pump sodium and potassium ions across their external
membranes. Nerve impulses are generated when these ions are
suddenly let back again to give sharp spikes of current.
Last
but not least, the membranes themselves (which are only two
molecules thick!) are held together electrically. They
consist mostly of negatively charged molecules bound
together by positively charged ions (mostly calcium), which
act as a kind of cement.
Unfortunately,
weak electromagnetic fields gently tease out some of these
calcium ions, which weakens the membranes and makes them
more inclined to leak. As a result, our bodies become less
efficient at generating energy and our nerve and brain cells
are more likely to generate false impulses.
False
impulses generated in sensory cells can give symptoms of
electrosensitivity, whereas those generated in the brain can
affect mental function and may also lead to stress
headaches. Even people who do not regard themselves as
electrosensitive, frequently get headaches and other
unpleasant symptoms when exposed for long periods to the
radiation from Wifi, cordless phones and mobile phones.
Other
reported effects from prolonged exposure to pulsed
microwaves include an increase risk of cancer and a loss of
fertility. This seems to be associated with observable
damage to cellular DNA, probably as a result of the leakage
of digestive enzymes from lysosomes (tiny particles in
living cells that digest and recycle waste) whose membranes
have been damaged by the radiation.
Pulses
carried by microwaves are particularly dangerous.
This is because their very short wavelength allows the
transmission of pulses with extremely rapid rise and fall
times, and it is the rate of change of the fields
(rather than their total energy) that does most of the
biological damage; it catapults vital calcium ions away from
cell membranes, which in turn makes them leak. This leakage
can explain the great majority of the observed adverse
health effects of prolonged exposure to electromagnetic
radiation (for more on this, together with references,
please visit http://tinyurl.com/55286a
).
It
is therefore unwise and arguably dangerous to be exposed for
long periods to the radiation from Wifi transmitters,
cordless phones and mobile phones (especially their base
stations, which run 24/7). They should certainly not
be deployed in public places until all the risks have been
independently evaluated. Any claims that they are harmless
because they do not generate significant heat are completely
unwarranted.
