Mobile brain help claim dismissed
BBC News UK Edition ^ | 22 September 2004

Experts say it is extremely unlikely mobile phone radio waves could help children think more clearly.

The claim had been made by David Butler, head of the National Confederation of Parent Teacher Associations. He told a meeting at the Lib Dem conference in Bournemouth, hosted by the mobile phone company O2, heat from handsets could boost children's brains.

The National Radiological Protection Board led the criticism of Mr Butler's claims, saying while handsets did have a tiny heating effect, it was unlikely to be of any benefit. The claims also contradict government advice, which says children should use mobiles as little as possible.

The mobile phone industry has also carried out extensive research into the safety of handsets and is adamant there is no link between usage and ill health. And the respected Stewart report, commissioned by the government on mobile phone safety, concluded there were no health risks. But the report did take a precautionary approach, recommending children should only use mobiles in emergencies because of the theory that they could be more at risk from the radio waves because their brains are still developing and their skulls are thinner.

'Weigh up evidence'

David Butler told the conference fringe meeting: "From a perspective of pupil performance it can enhance things, because that heating effect actually improves the neuron transfers between neural pathways, and therefore your thinking ability goes up. He said he had been told of the evidence by a British professor. But he would not identify the scientist. He stressed the information was "anecdotal" but added: "I have yet to see there is actually evidence that that would create a health problem."

"But I mean, even frankly if there was, I would still be wanting to weigh up what someone was telling me about a health problem against the other benefits that that technology was giving. What I am saying is that any parent has to weigh up what is perceived to be the risk in any situation, and then use whatever means they feel appropriate to minimise that risk."

"I personally have not seen any piece of paper that says to me there is a health risk, which would give me concern."

But Dr Zenon Sieniewicz, science officer for the National Radiological Protection Board (NPRB): "Mobile phones do undoubtedly have a heating effects, but it's been measured at a fraction of one per cent." He added: "Some early studies did show a slight increase in reaction time in cognitive tests. These could be detected in the laboratory, but probably not in real life. "And later studies have shown a smaller effect, or no effect at all. It seems likely that a small amount of heating happens, but it's unlikely there would be a significant amount of enhancement."

Dr Sieniewicz said children should continue to abide by the precautionary advice, and use their phones as little as possible.

Christine Mangat, joint co-ordinator of Mast Action UK, said she recognised that there had been claims which suggested that thermal heating, effectively exposure to microwaves, improves reactions and responses.

But she added: "Mr Butler is cherry-picking a bit of information when there is a whole mass of information that would be contradictory.

"It is not recommended that young children do use mobile phones. Under the age of eight, their brain is still developing."

So wouldn't just wearing a hat have a beneficial effect, too?

The claims also contradict government advice.

Heaven forbid!

This has been going on a while, the speculation that RF near the skull has some effect or the other, but this David Butler is just out there, and he's not doing any justice to the truth.

20-25 years ago when HTs started getting real popular folks started hearing things about the RF from them being a cause of cancer, but I don't think any studies have shown anything causative there or even any association.

There was something a while back about some problems with cops who used hand held radar guns a lot, but there you have RF at much higher power levels, at higher frequency, and a more narrow beamwitdth, so such a signal, if it is potentially detrimental, would be more apt to be so than 2-5 Watts from a HT or the 250 mW or so from a cell phone. If there is any affect good or bad from a cell phone I don't think it would be from heat because there's no way one could possibly generate heat in tissue that would bring it outside of the normal body temperature range.

Going back to the radar units - yeah there might be something there - there was a higher incidence of cancer in lower abdominal areas in cops who kept speed guns powered up and sitting in their laps (not done much anymore thanks to the newer technology of vehicle mounted smart radar units and hand held laser units). You can also get burned if you are a tower worker who missteps into the beam of a high power microwave dish.

Get them a cell phone with speaker-phone built in. Mine is outstandingly handy.

David Butler told the conference fringe meeting

Talk about a fringe meeting...

I have seen people with cell phones practically glued to their heads. Yak, yak, yak, yak, yak. Yada, yada, yada. Five minutes standing in line at the grocery store -- oh, goody, just enough time for another phone call! Probably a $200 per month phone bill for all the conversations about the games or the soap operas. What is really fun is when a driver is yaking on the phone, running stop signs, as if to say, "LOOK AT ME! I AM SPECIAL! I HAVE A PHONE SURGICALLY ATTACHED TO MY HEAD! IT MIGHT BE SCRAMBLING MY BRAIN CELLS, SO GET OUT OF MY WAY! I have not observed that mobile phone use has enhanced anyone's intelligence.
