According to a major safety review for the UK’s Health Protection Agency (HPA), there is still no evidence mobile phones harm human health.

Scientists looked at hundreds of studies of mobile exposure and found no conclusive links to cancer risk, brain function or infertility.

However, they said monitoring should continue because little was known about long-term effects.

The HPA said children should still avoid excessive use of mobiles.

It is the biggest ever review of the evidence surrounding the safety of mobile phones.

The study said exposure to low-level radio frequency fields was almost universal and continuous because of TV and radio broadcasting, Wi-Fi, and other technological developments.

A group of experts working for the HPA looked at all significant research into the effects of low-level radio frequency.

They concluded that people who were not exposed above guideline levels did not experience any detectable symptoms.

That included people who reported being sensitive to radio frequency.

They also said there was no evidence that exposure caused brain tumors, other types of cancer, or harm to fertility or cardiovascular health.

But they said very little was known about risks beyond five years, because most people did not use mobile phones until the late 1990s.

Prof. Anthony Swerdlow, who chaired the review group, said it was important to continue monitoring research.

“Even though it’s relatively reassuring, I also think it’s important that we keep an eye on the rates of brain tumors and other cancers,” he said.

“One can’t know what the long-term consequences are of something that has been around for only a short period.”


There has been speculation about the health effects of using mobile phones for years.

The HPA conducted a previous review in 2003, which also concluded that there was no evidence of harm. But there is now far more research into the subject.

The experts said more work was needed on the effect of radio frequency fields on brain activity, and on the possible association with behavioral problems in children.

They also called for more investigation into the effects of new technology which emits radio frequency, such as smart meters in homes and airport security scanners.

The HPA said it was not changing its advice about mobile phone use by children.

“As this is a relatively new technology, the HPA will continue to advise a precautionary approach,” said Dr. John Cooper, director of the HPA’s centre for radiation, chemical and environmental hazards.

“The HPA recommends that excessive use of mobile phones by children should be discouraged.”

 

The already “extreme” risk of a flu pandemic spreading in the UK will increase during the Olympics, a report has said.

Britain has been ranked by analysts Maplecroft as second only to Singapore for the speed at which influenza could spread, because of its dense cities and status as a global travel hub.

The report said the “large influx of visitors” at Olympic Games time would raise the “already significant” risk of spread.

But the Health Protection Agency (HPA) disagreed, saying the risk was low.

“We have done our own review and we don’t believe that there is a risk,” said Dr. Brian McCloskey from the HPA.

“We have sporting events and music festivals all around England and we had the swine flu pandemic at Glastonbury. We also looked at research from the Vancouver Games – neither produced any significant problems.”

Dr. Brian McCloskey said that at Glastonbury in 2009, hundreds of thousands of people were densely packed in fields together for days at a time during the outbreak of influenza strain H1N1.

Whereas he said at London 2012 visitors would only be at the Olympic Park for four or five hours, so the risk was reduced.

Maplecroft’s influenza pandemic risk index rates five countries at the “extreme” level of risk for the pandemic spread of the disease, with Singapore top, followed by the UK, South Korea, the Netherlands and Germany.

The study said that the Olympics would increase the danger of flu spreading because of the extra 5.3 million overseas tourists expected to visit Britain for the Games.

But it also found that Britain was in the top 10 of countries best placed to withstand any outbreak.

The Department of Health (DoH) said that the NHS had contingency plans in place for any eventuality.

“Outbreaks of infectious diseases during the Games have been very rare,” a spokesperson said.

“The Health Protection Agency (HPA) responds to over 5,000 disease outbreaks each year and has robust systems and processes in place to do this.

“There is a comprehensive testing and exercising plan in place to make sure that all systems are ready.”

Dr. Brian McCloskey said the chance of flu spreading during sporting events was quite low.

“It is much the same as it would be in any summer,” he said.

“The fact lots of people are going to London during the Games, doesn’t really change it.

“We have to be very careful about new diseases coming in but that doesn’t mean we are high risk. Conditions won’t be as such during the summer to make flu spread easily.”

He added that the HPA would not be recommending any specific health precautions, other than those it already gives.

“Our normal advice would be if you feel unwell then stay at home. Then there is the standard advice we give across London at all times about sneezing, coughing and washing your hands.

“The simple advice would be, don’t worry. But anyone feeling unwell – where they feel there is a cold, or have diarrhoea and vomiting then stay at home and don’t bring it out with you.

“It’s not an area people should worry about in any sense.”

In January a series of reports, in The Lancet Infectious Disease journal, highlighted the risks of mass gatherings, such as London 2012.

Health experts said they can be a hotbed of diseases from across the world – the theory being that so many people, packed closely together, increases the risk of diseases spreading.
