Radiation from mobile phones may cause brain tissue damage, a two-year study has found.
Scientists discovered that emissions from handsets affect the delicate make-up of cells in blood vessels, and could be a health hazard to regular users of the UK’s 50million mobile phones.
The radiation might disable a safety barrier in the body which protects the brain from harmful substances in the blood, they believe.
It is the first time scientists have used cells from human blood vessels rather than rats, bringing researchers closer to the truth about long-term mobile phone use.
Despite the millions spent on research in the last decade, the health implications of sustained use are still unclear.
The biggest British study, led by Sir William Stewart, found two years ago that there was no evidence of a risk to health. A study published last year by the American National Cancer Institute also could not find a link between increased risk of brain cancer and mobile use.
But the latest study by the Radiation and Nuclear Safety Authority in Finland – the home of mobile phone giant Nokia – has found that one hour of mobile radiation triggered potentially harmful changes in human cells.
The radiation made the cells in blood vessel walls shrink – allowing potentially harmful substances in the blood to ‘leak’ into the brain.
Repeated exposure, the study found, could make the blood-brain barrier more permeable, leading to increased brain damage.
It concluded: ‘Repeated occurrences of these events on a daily basis, over a long period of time, could become a health hazard due to possible accumulation of brain tissue damage.’
Professor Dariusz Leszczynski, who led the study, said: ‘There is massive use of mobile phones in society now; our brains are being bombarded with radiation all the time.
‘We really don’t know what the impact is going to be on people regularly using a mobile phone for ten or 20 years. That is why more studies are urgently needed.’
Mobile phone radiation may also contribute to the growth of tumours caused by other factors, he said.
