- It's Official - Cell Phones DO Scramble Your
Brains

-
- MOBILE phones do scramble your brains, a
Government study has confirmed.
-
- A report by experts at Bristol University shows
that microwaves from mobiles affect your nervous system.
-
- It is disturbing news for Britain's 13 million
mobile phone users, who have been bombarded with conflicting information about potential
dangers.
-
- Official advice says as long as mobiles conform to
Government guidelines on heating your brain, they are safe.
-
- But critics of the industry have long believed it
is not the heating effect which could cause long-term damage - but the scrambling effect
on the brain's electrical impulses.
-
- The study carried out on 36 volunteers clearly
showed mobiles make us react faster in certain situations - a brain function which is
controlled by electrical flow.
-
- The report - due out next week - was not intended
to address fears about cancer risks.
-
- But Dr Alan Preece, who led the study, concludes that
mobile radiation does affect the brain, principally the part of the brain's cortex which
links speech and vision.
-
- Last night experts said the Government-funded
study was too small in its scope, but admitted it gave grounds for concern and proved the
need for more widespread research.
-
- Microwave radiation expert Alasdair Philips of
consumer watchdog Powerwatch said volunteers were subjected only to small amounts for
about 25 minutes at a time.
-
- "But the fact that it showed any effect at
all means there is an urgent need for a repeat of this work with many more people and
longer exposure times."
-
- Each volunteer was fitted with a headset attached
to a mobile phone simulator in the tests at Bristol Royal Infirmary.
-
- They were subjected to analogue and digital
signals and tested to measure their mental efficiency and reaction time.
-
- Volunteers responded more quickly in one test when
subjected to microwave radiation - meaning it had affected the central nervous system.
-
- Responses were faster to analogue signals, which
are continuous, than to digital signals, which are broken up.
-
- Yesterday the Sunday Mirror tracked down one of
the human guinea pigs.
-
- Mother-of-two Sue Pycock, 48, put on the
headphones and watched 10 versions of a similar image and memorised them.
-
- A second sequence was shown and she had to respond
by pressing a button every time she saw one from the previous set.
-
- A computer recorded the accuracy and speed of her
responses. Sue, of Clevedon, Somerset, said: "Some of them were tricky but most were
pretty easy - I don't know if that had anything to do with the microwaves."
-
- Experts pointed out that Dr Preece did not use
real mobile phones but microwave simulators.
-
- A digital mobile emits low-frequency magnetic
field pulses as well as microwave radiation.
-
- These are created by the battery switching power
on and off 217 times a second as signals are sent by the mobile. They pass right through
the head and out the other side.
-
- Mr Philips said: "These low-frequency fields
may have a greater effect on performance such as memory than microwave radiation."
