Hi Everybody,
Recently I stumbled upon an alarming news about the health-effects of Wi-Fi networks in the following link.

The use of wireless computer networks in classrooms should be immediately suspended until an inquiry has fully investigated the health threat to millions of pupils, a teachers' chief urged yesterday.
Philip Parkin, the General Secretary of the Professional Association of Teachers, said that children were effectively acting as guinea pigs because the risk posed by 'wi-fi' networks had not yet been thoroughly considered.
He said scientific evidence prompted him to question the safety of the systems already introduced in 15,000 schools across the UK.
Wireless technology has been linked with loss of concentration, fatigue, reduced memory and headaches. There are also claims that it could increase the long-term risk of cancer.
Addressing the PAT's annual conference in Harrogate, Mr Parkin said: "My real concern is that until there is a full inquiry based on both existing evidence and on newlycommissioned research work, the nation's children are being treated as guinea pigs in a large-scale experiment."
Mr Parkin's demand for an inquiry follows a similar call from Britain's top health watchdog, the chairman of the Health Protection Agency.
Sir William Stewart said in May that a review of the health effects of wi-fi networks was 'timely' amid fears they could pose greater dangers than previously thought.
Wi-fi systems use high frequency radio waves to transmit and receive data over distances of several hundred feet.
They allow users to surf the internet within range of a wireless transmitter and remove the need to connect via a cable.
A typical comprehensive has ten wi-fi transmitters spread around the premises. If a school has thick walls, there may be many more. Children are thought to be more vulnerable to electro-magnetic radiation due to their thinner skulls and still-developing nervous systems.
