There is controversy over the health risks, and debate over whether there has been sufficient control over the use of Wi-Fi in the classrooms.

First off, the article is from last July so it's hardly news. "WiFi is scary. The Loch Ness monster is scary. We don't actually know anything about either of them, but we once saw a programme on TV that said they were, and it had a nice theme tune. Now if you'll excuse me, I need to go make a tinfoil hat..."

In terms of WiFi it answers its own question by quoting from the HPA:-

---
The agency says: ‘On the basis of current scientific information Wi-Fi equipment satisfies international guidelines. There is no consistent evidence of health effects from RF exposures below guideline levels and therefore no reason why schools ... should not use Wi-Fi equipment'.

The Health Protection Agency says that exposure to Wi-Fi radio waves is comparatively low compared to that of mobile networks — 20 minutes on a mobile phone is equivalent to a year spent in a wireless classroom.

The last part of the article, discussing how a classroom based heavily on the use of display screens would compare to workplaces operating under DSE is of more interest, as it's the only part of this where there's actually a valid health argument. Kids don't work on laptops all day yet, but in a few years they will be.
