Over the last few weeks, a bit of a storm has erupted over Airtel's applications to spackle the island with the masts required to run the island's third mobile phone network. Naturally there's some serious questions to be answered about these potential eyesores, why they are necessary and why they couldn't share existing sites.
However, lately the furore has largely focused on health implications. Most recently on Tuesday, Mr Roger Coghill rolled in to the island to give a talk at St Martin's Community Centre which has been widely and uncritically reported in the media. The Press proclaims him to be an 'electromagnetic energy expert' and a 'research scientist', and BBC Guernsey never miss an opportunity to point out that he is 'Cambridge-educated'.
But dig a little deeper, and it seems things are not quite what they appear.
As the Press notes (nearly) correctly, Coghill became quite prominent in 1998 when he published independent research arguing that RF emissions from mobile phones damage the immune system, and attempted a private prosecution against a mobile dealer arguing that under the Consumer Protection Act he should be displaying warning labels on phone packaging.
Coghill lost the case. His research was not published in any peer-reviewed journal, and as such represented nothing more than his opinion. More importantly, it was not corroborated by other peer-reviewed studies. But that didn't stop both the case and the research generating a huge amount of media interest: Coghill was cited 119 times in the media between 1998 and 2003, fuelling considerable public fear over the safety of mobile phones.
Around the same time, Coghill set up
Coghill Research Laboratories. For the last ten years, he has been conducting research there into the effects of magnetism, electric fields and non-ionising radiation on living tissue.
Coghill has published very few papers in peer-reviewed journals (especially if you don't count papers in
European Biology and Bioelectromagnetics, a journal set up by Medcross Group which in turn was founded by... er... Roger Coghill). Of those which have, none effectively demonstrate a causal link between EMR (electromagnetic radiation) and negative health effects.
Nor do any of them provide evidence for the health benefits of Coghill's products,
peddled via his website. These consist of a variety of alternative therapy books, highly dubious 'therapeutic' pendants and bracelets, mobile phone shields, and the modestly-named 'Coghill SuperMagnet', which is... er... a magnet. It's a very expensive magnet though, so it must be good at... whatever it does...
So what? The guy's a bit iffy - but there's still lots of research to indicate there are risks from mobiles, right?
Well, it is true that even though we know a lot more than we did 20 years ago, mobile phone masts are still not guaranteed to be safe. Millions of pounds are being poured into epidemiological studies to continue to examine the long-term effects of mobile phone emissions, and rightly so.
But with each study which comes up negative, with the benefit of ever longer case histories to examine, and with each literature review which whittles out the chaff from the previous studies, the odds that we will discover any health risks in a future study get smaller and smaller.
Despite this increasing body of evidence, surveys conducted in Europe, the UK and the US generally indicate that about 3% of the population suffers from a condition known as 'electromagnetic hypersensitivity syndrome' (EHS). This is a recognised condition with symptoms like stress, nausea, headaches and joint pain. The problem for scientists is that it is not known what causes EHS. A number of 'provocation studies' have been conducted into this - basically subjects who claim to have EHS are tested to see how the presence or absence of a mobile phone signal affects their symptoms.
One such
study was published by Essex University yesterday and made headline news nationally. In fact there have been more than 30 similar studies published in the past. Most of these gave similar negative results to the Essex study - the few that didn't were either demonstrably flawed, couldn't be repeated even by the same researchers, or had mutually contradictory results.
However, what the provocation studies do show is that although EHS is not caused by the presence of mobile phone signals, subjects are afflicted with EHS when they
believe that a signal is present.
Many media outlets have reported this result as saying that EHS is 'all in the mind', but that's not helpful because it belittles the very real and sometimes debilitating effects of EHS - a bit like dismissing depression as being 'all in the mind'. Though other causes of EHS cannot be ruled out, the most plausible explanation is that many subjects suffering from EHS are experiencing the consequences of anxiety brought on by their own fear of 'electrosmog'.
Coghill believes (or at least says he believes) that mobile companies are engaged in a conspiracy to fund biased studies, stymie true research, and cover up the true dangers of mobile technology. True, a lot of research into mobile phone risks is sponsored by mobile phone companies, but that's why there is a scientific peer-review process. What would Coghill be saying if the mobile companies refused to fund this research?
In reality, campaigners such as Coghill are always poised on the sidelines to pump the media with misinformation over any health scare, justified or not, and the media's blind acceptance of their authority converts this into public fear. Whilst Coghill reaps the rewards and boosts his notoriety, the well-being of around 2 million EHS sufferers in Britain alone is in jeopardy.
