Health Worries over Wireless Networks

Following concern over the long-term effects of Wi-Fi Internet networks, the government have ordered an inquiry into their potential health risks. This move comes just a month after Philip Parkin, general secretary of the Professional Association of Teachers, suggested that the use of wireless networks should banned from schools until a full investigation into their health risks is conducted. Indeed, a number of schools have already withdrawn Wi-Fi connections from their classrooms.

It is believed that wireless networks could potentially release the same kind of electromagnetic radiation as mobile telephones. A recent Swedish study found that long-term users of mobile phones were two and a half times more likely to get tumours. However, Peter Lyons of the Open Learning Partnership – an organisation that fits Wi-Fi networks in hospitals – believes that the radiation omitted from wireless networks would be significantly less. He said: “Wi-Fi gives out a far less powerful output than any mobile phone mast. The radiation is less than you would get from a microwave oven.”

During the two-year inquiry, the Health Protection Agency (HPA) will eventually monitor and test levels of exposure in offices, homes and classrooms. However, the investigation will begin in a laboratory; using computer models to measure the strength of signals omitted by wireless base stations. They will also use dummies in the tests, which will be fitted with radiation monitors to assess the level of exposure to the head and rest of the body. Philip Parkin believes such a thorough investigation is vital. He said: “What we want is a thorough investigation that can either confirm there is something to worry about, or completely assuage any fears people might have about Wi-Fi.”

After the testing, the HPA will compile a health-risk report, which will be submitted to the government for publication. If the findings highlight a health risk, it is expected that further safety guidelines will be drawn up.
