Scientists analyse health risks linked to mobile phones
Transcript 15/12/2000
KERRY O'BRIEN: Mobile phone manufacturers were reluctant
to participate
in this program. And Health Minister Michael Wooldridge, who
is
responsible for regulating safety standards, explained he
didn't
participate in panel discussions. But we're joined tonight
by three
scientists who are experts in the field.
From Nottingham, England, I'm joined by Professor Lawrie
Challis,
emeritus professor of physics at Nottingham University and
vice-chairman
of the Stewart Group.
In Melbourne, Dr Andrew Wood, a biophysicist from Swinburne
University.
He's finalising two studies into the health effects of mobile
phones --
one funded in part by Telstra, the other, part of an international
study
by the World Health Organisation.
And, in Sydney, Dr Peter French, a cell biologist from Saint
Vincent's
Hospital's Centre for Immunology. Dr French is researching
the
biological effects of electromagnetic fields.
Gentlemen, welcome to the program.
KERRY O'BRIEN: Peter French, what fundamental concerns do
you have about
the safety of mobile phones?
DR PETER FRENCH, CELL BIOLOGIST, CENTRE FOR IMMUNOLOGY: I
think that
that report demonstrates the way that the field has evolved
over the
past five years. Initially, the results or fears were greeted
with
scepticism because it was inherently assumed by all, including
the
industry, that low-power fields, such as those produced by
mobile
phones, were biologically inert. We now know -- and I think
the Stewart
report stated that fairly clearly -- that biological effects
from those
sorts of fields are now a reality, demonstrable by us and
by several
groups around the world. The question is, if the first assumption
--
that is, that effects on biological systems are not present
from this
sort of radiation -- is found to be wrong, there's a second
assumption,
that there are no adverse health effects, also going to be
proven to be
wrong once we know more. And I think that's the nub of the
question now.
KERRY O'BRIEN: But, right at this moment, you don't dispute
that there
is no conclusive proof of health effects from mobile phones?
DR PETER FRENCH: I think that conclusive proof is still a
fair way away.
But I believe that there is sufficient biological evidence
now to be
able to postulate a mechanism which can lead to serious adverse
health
effects, including, but not restricted to, cancer.
KERRY O'BRIEN: Andrew Wood, from your work, do you have any
concerns
that there is risk in the use of mobile phones or not?
DR ANDREW WOOD, SWINBURNE UNIVERSITY: Well, the experiments
that we have
done have been looking at whether the calcium levels in cells
are
altered by mobile phone radiation. Certainly we've had no
indication in
those experiments that there are any changes. I must say that
these
sorts of experiments that have been reported for about 25
years, so it's
not as if we've suddenly come across this problem.
KERRY O'BRIEN: And, given all of your knowledge of that previous
research and your own work, how clearly can you postulate
whether you
believe there's any risk or not?
DR ANDREW WOOD: I think one of the difficulties always is
to try and
estimate what the actual absorption is in tissue. Certainly,
in our own
study, we spent a long time using mathematical modelling techniques
to
work out exactly what the amount of absorbed energy was in
the sample.
And there always is this question as to whether we're really
looking at
levels that are so-called non-thermal -- that is, below the
level that
you'd expect some sort of heating to occur.
KERRY O'BRIEN: OK, but where Peter French is prepared to
acknowledge
that there is yet no evidence to say conclusively that there
is risk, I
assume equally you're prepared to acknowledge that there is
no
conclusive evidence that there is no risk.
DR ANDREW WOOD: It's difficult to prove a negative, always.
Certainly,
the effects that we understand well -- that is, the heating
effects of
tissue -- are really well understood. The question really
is whether
there are other effects that aren't due to tissue heating.
But really
there's been no clear indication of what that mechanism might
be. It's
very hard if we don't know what the mechanism is to be able
to evaluate
whether such effects are occurring.
KERRY O'BRIEN: Lawrie Challis, from your perspective as vice-chairman
of
the Stewart Group in Britain, reviewing all of the evidence,
how do you
react to what you've heard so far tonight?
PROFESSOR LAWRIE CHALLIS, STEWART GROUP: Well, I don't disagree
with
what's been said tonight. But I think that we looked at about
430
scientific papers in this field. And we came to the conclusion
that
there is no strong convincing evidence that there are health
effects.
However, we also feel that there may well be biological effects.
I think
one really needs to distinguish between biological effects
and health
effects. We can see each other. That's a biological effect
-- at the
light levels we can see. But, if we shine a laser or look
at the sun in
our eyes, then we produce health effects. That's a pretty
obvious
statement. That's the distinction between a biological effect,
which is
helpful to us and -- or certainly not intrusive -- and a harmful
effect,
which obviously we want to avoid. We just don't know where
we are on
that range.
KERRY O'BRIEN: To what extent was your group influenced by
that finding,
that recognition that mobile phones do create, or can create,
or might
create some biological effect?
PROFESSOR LAWRIE CHALLIS: We were influenced by that. We
clearly feel
that is an important pointer. Till a few years ago, I don't
think we
would recognise that we could detect -- our bodies could detect
biological effects from this sort of radiation at this sort
of level.
Now we believe we can, and so we clearly need to do more work
to find
out are there any health affects associated with that.
KERRY O'BRIEN: Andrew Wood, you accept, don't you, that mobile
phones
may cause some biological effects?
DR ANDREW WOOD: Well, certainly, there have been a number
of studies
showing that human ability to do things like intelligence
tests and
memory tests seem to be altered. Again, that is a biological
effect. I
guess, it's difficult to make an estimate as to whether that
would
constitute a health effect.
KERRY O'BRIEN: But, where I think for a long time the telecommunications
industry has tendered to argue that there was no biological
effect, that
is a significant finding, isn't it?
DR ANDREW WOOD: I must say that, if you look at the studies
that are
reporting this, there are some important differences in their
findings.
They're not entirely consistent. Their findings may in fact
be due to a
statistical fluke, if you like. It could be just due to chance.
KERRY O'BRIEN: Peter French, what significance do you read
into
biological effects from mobile phones?
DR PETER FRENCH: I think that what Andrew has just said is
very
important to bear in mind -- that is, that mobile phone radiation
is not
inert. It can produce physiological effects in people. As
Andrew says,
that doesn't necessarily lead to an adverse health effect.
But, given
the fact that energy is being deposited into the brain from
mobile
phones, what else might it be doing? I think there's some
very
interesting work that's been done in cells and in animals
which shows
that there may be a fundamental mechanism common to all those
findings
that could indeed lead to an adverse health effect for a significant
number of people.
KERRY O'BRIEN: Lawrie Challis, I assume that that was why,
in the end,
you came down with what you've called a cautionary approach
-- that is,
you've given some benefit of the doubt to the possibility
that there may
be risks.
PROFESSOR LAWRIE CHALLIS: We felt that, on balance, the position
was
such that the consumer, the user, should have a transparent
view, should
have a clear view of what the situation is. We felt that the
sort of
advice we gave -- I don't know if you want me to go through
the advice
we gave -- but certainly we recommended people should use
them less,
particularly children. And we recommended that people should
use a phone
that gives them less exposure -- and shortly we shall have
good
information on how much each phone gives out. And a whole
series of
things which I can go through if you wish.
KERRY O'BRIEN: What about the issue of the placement of mobile
phone
towers because many of them you will see, certainly in this
country,
next door to kindergartens or fire stations or smack in the
middle of
residential areas, playing fields, clubs and so on.
PROFESSOR LAWRIE CHALLIS: Well, I think the first thing to
recognise is
that -- I mean, certainly in the UK we have five public meetings.
Certainly in the UK it was very clear this issue of masts
produce more
public concern, than the issue of phones, which is obviously
a bit
paradoxical because the exposure you get from a mast is probably
1,000
or times or more below guideline levels whereas from a phone,
as I've
said, it's approaching guideline levels. So it's a little
paradoxical.
Even so, we felt that, because there was so much public concern
about
this, the Government need to respond to this concern. And
we did advise
that care should be taken in the neighbourhood -- in sensitive
areas
such as schools. I think there's another point that really
needs to be
made that we didn't make in the report and I regret it. If
you reduce
the amount of radiation, the amount of strength of the radio
waves that
a user is getting, the user's phone will beam up. So, if you
are a
person, say a child in a school play ground, you're going
to get far
more radiation from your phone if the mast is from a long
way away than
if the mast is relatively nearby. So you've really got to
balance that one.
KERRY O'BRIEN: Peter French, briefly.
DR PETER FRENCH: I think the real issue is the concern with
mobile
phones. I think the amount of power that one gets from mobile
phone
masts is very much less and likely to be biologically inert.
KERRY O'BRIEN: There's also been some controversy about whether
the
hands-free use of mobile phones is a positive or a negative,
whether
it's riskier or less risky.
PROFESSOR LAWRIE CHALLIS: I'm personally believe it is possible
to
design a hands-free kit that will reduce the exposure to the
head. But,
of course, the present set of hands-free kits were not designed
to
reduce the exposure to the head since it's well within the
guidelines,
they were intended to allow you to use them hands-free. So
they weren't
really the optimum design perhaps for reducing exposure to
the head. I'm
sure they can be done. And we need to do that work very fast.
KERRY O'BRIEN: Very briefly, Andrew Wood or Peter French,
does either of
you have a view on this?
DR ANDREW WOOD: Well, I'm aware of two studies done here
in Australia on
hands-free kits and they both show a substantial reduction
of radiation
to the head -- something like 94 per cent.
KERRY O'BRIEN: Peter French, briefly.
DR PETER FRENCH: All I can say is that I use a hands-free
kit.

City
wide DECT network in Oradea (Grosswardein), Romania, Eastern
Europe
Hi Klaus,
Iris gave your address to me. My city's problem is described
here in English:
http://www.usbiz.ro/digit/show-news.php3?id=11998
I was shocked by this phrase:
"Atlas Telecom's CEO and chairman for Central and Eastern
Europe,
Pompiliu S. Tripa, says this is also the first DECT metropolitan
network
in the world."
Why in Oradea, Romania, where the cancer is already the leading
"killer"
?! Why not in some western country with well developed technologies
and
lots of money ?
I'd like to found out if there are other DECT metropolitan
networks used
as Wireless Local Loop (WLL) around the world and are they
dangerous or not.
I know there are many DECT users in China and Taiwan, but
in Germany too.
You can inform everybody about this "first DECT metropolitan
network in
the world" and I wait for peoples reaction.
Thank you!
P.S. You can find a thread about this problem here:
http://www.softnews.ro/forum/showthread.php?s=&threadid=14064
Sorry, it's mostly in romanian, but there are quotes from
Iris too, and
from other wevsites also.

RE:
Sprint is coming to town; Berkeley, California
Of course you should go! And you should steal the floor and
put out GOOD
information and not personal "concerns".
And you should bring your own expert to slam-dunk any false
scientific
or legal claims they might make. You should leaflet people
there with
fact sheets from which they can quote, and which preemptively
disprove
what Sprint will say.
What's the date?
And what do they say the agenda will be?
Informant: Susan Clarke
and the answer:
The news from Berkeley, California is that Sprint plans to
talk about
disguising the antennas as chimneys. You see, they plan to
bypass all
other concerns.
The info session by Sprint is on August 7, at the North Berkeley
Senior
Center. We wish lots of people go to the meeting.

THE
WTO UNMASKED
Greenpeace Activist News, Vol. 3, No. 7
1 August 2003 (excerpt)
With the next World Trade Organisation meeting in Cancun
coming up
during 11-14 September, here are a few things you can do to
protest the
WTO's prioritisation of corporate profits over the health
of our planet
and its people.
Genetically engineered food by Bush & Co.
The US and corporations behind genetically engineered (GE)
food are
using the World Trade Organisation to tell the world what
to eat and
where to buy it from.
Supported by Canada and Argentina, the US is trying to use
the WTO to
challenge the European Union's policy on genetically modified
organisms
(GMOs) - a policy that is the strictest in the world. The
US challenge
amounts to a scare tactic to "encourage" countries
to open their markets
to GE food. Many countries fear that if they reject GMOs,
they will be
met with huge trade sanctions potentially worth hundreds of
millions, or
even billions of dollars.
Introducing "Genetically engineered food by Bush &
Co.". Political
cartoonist Mark Fiore has designed this great e-card for us
to protest
corporate attempts to take over our food chain. Support the
global
movement for the right to say no to GMOs and spread the word
by sending
it to your friends and colleagues:
http://act.greenpeace.org/ecs/s2?i=863&sk=std
While you're sending those e-cards, don't forget to take
part in the
cyberaction to tell Argentina and Canada to stop supporting
the US war
on consumers, farmers and the environment:
