Well, what did everyone think?
While I personally think the potential danger does need serious investigation (as with any potential danger), I don't think that (if it happened as shown), the Panorama investigation was good. They appeared to have started with the premise that WiFi and mobiles are dangerous and then spent half an hour trying to prove that.
I have to admit, I am not sure if I agree with WiFi being installed in classrooms (if there is even a risk of cancer, why expose our kids to it), but that doesn't mean I don't think it is safe.
All the programme showed us was a series of (apparently) well known scientists who said WiFi was bad, one scientist who said it wasn't (who they then pointed had once worked for a mobile phone company so obviously they were saying his opinion was tainted) and a woman who said she got headaches. Then she proceeded to cover her house in tinfoil (which can be a sign of *ahem* problems).
One final point: Wouldn't covering her walls, and not the windows actually reflect the waves within the room? Therefore making the problem worse?
BTW, there is an interesting article on the programme on El Reg.
