Hey, teacher! Leave our kit alone!
Nine months after the last W-Fi/cancer scare the techno-fear brigade are at it again, warning of dying children as we know it due to wireless routers and Bluetooth headsets.
Teachers have demanded education secretary Alan Johnson (recently at the heart of the Wikipedia scandal) to investigate the potential health risks posed by Wi-Fi networks. Some schools have already scrapped wireless networks in favour of traditional wired alternatives.
According to our very own story on this issue, up to 80 per cent of UK secondary schools and 50 per cent of primary schools have Wi-Fi equipment installed.
Philip Parkin, General Secretary of the Professional Association of Teachers, said: " I am not saying there is a danger, but I have enough concern to ask for it to be investigated."
As a parent myself I'm happy that Phil is concerned, but he needn't be.
As we we reported way back last July, the risk from mobile phone towers has yet to be proven, yet these operate at 10,000 times the power of our little Wi-Fi units. FM radio towers are 100,000 times more powerful.
Schoolboys and girls are far more likely to develop tumours by inadvertently listening to the staff room radio than they are by packets of data flying invisibly around the playground.
