Powerwatch UK, an independent consultancy service on the danger
of mobile phones, cell phone dangers and phone masts, has received
as many complaints about DECT cordless phones as they have about
mobile telephones: headaches, earaches, extreme fatigue, concentration,
memory loss, etc. Dr. Peter French of St. Vincent’s Hospital,
Sydney, Australia reported that he has recently heard of three
cases of lymphoma (lymph cancer) linked to excessive use of cordless
telephones. In the principal case he described, the primary lesion
was on the neck. The dead woman had used her cordless ‘phone
up to four hours a day for 2-3 years.
Whereas mobile phones power down automatically to ensure that
the user receives the smallest dose of radiation possible without
damaging reception, DECT cordless telephones emit fixed 250 milliwatt
pulses wherever they are - 100 bursts every second. Many scientists
believe that these can interfere with the brain’s intercellular
signalling.
Cordless phones also emit low level frequencies. These are typically
5000 nanotesla in strength. Many studies have linked childhood
leukaemia to exposures as low as 250 nanotesla fields.
Cordless phone base units also emit both microwaves and low frequency
fields. It is important to site them at least six feet from where
you habitually sit or sleep. Remember when choosing the least
harmful spot that low frequency fields travel through walls. Base
units emit low frequency fields all the time they are plugged
into the mains, and further fields whenever the phone rings. These
secondary fields cut out if you take the call on an ordinary (wired)
telephone.
If you use a DECT cordless near its base, it is even worse. You
will be getting a triple dose of electromagnetic fields.
Alasdair Philips of Powerwatch recommends that children are never
allowed to use DECT cordless telephones. His overall advice for
DECT cordless phones is the same as his advice for mobile telephones:
- use an ordinary wired telephone whenever
possible
- when you have to use a DECT cordless, keep
call times below two minutes
Ed.- Most cordless telephones made in the last few years have
been made to the Digital European Cordless Telephone (DECT) standard.
Unlike the older analogue cordless phones, which operated at a
lower frequency and did not pulse, DECT models emit continuous
pulses of microwave radiation of around 1,900 MHz, frequently
modulated at 100 Hz. These signals are very similar to those emitted
by mobile phones.
The average strength of cordless phone microwave fields is 10mW,
with a peak of 250mW. This is similar to the exposures of people
living near to mobile phone masts or mobile phone 'base stations',
the signal boosters often attached to walls in built up areas
or disguised as (e.g.) burglar alarms or trees.
