WiFi fears not proven

22nd May 2007

Leading scientists have played down suggestions of a link between the use of WiFi technology and damage to people’s health.

The debate on the subject arose after the BBC programme Panorama went to one school in England and found that the radiation levels from WiFi were up to three times that of mobile phone mast radiation.

However, the readings were still 600 times below the government’s safety limits.

One expert, Professor Lawrie Challis of Nottingham University, who is also chairman of the Mobile Telecommunications and Health Research programme management committee, said that WiFi seemed “unlikely? to pose any health risk adding that exposures to WiFi are usually very small because there is a low power transmitter that is usually situated well away from the body. He did say, however, that children should be encouraged to use laptops on a table rather than on their lap.

But the Health Protection Agency (HPA) chairman Sir William Stewart told the Panorama programme that there was evidence that low-level radiation from devices such as mobile phones and WiFi did cause adverse effects on health.

The HPA say that sitting in a WiFi hot spot for 12 months gives the same level of radio waves as a 20-minute mobile phone call. The intensity of WiFi radiation is also put at 100,000 times less than a domestic microwave oven.

Medical physics expert Professor Malcolm Sperrin said WiFi radiation in a particular school at three times higher than a mobile phone mast was irrelevant, unless there was any evidence of a link to health effects.

The comment by the HPA chairman is inconsistent with the advice on the HPA website, which says: "On the basis of current evidence, the HPA does not consider there to be a problem with the safety of WLAN".

I'd like to feel more reassured about this important issue.
