Where’s evidence that Wi-Fi is safe?

Today’s Sky News report that teachers are calling for a full scientific investigation into wireless computer systems, following reports of electromagnetic radiation among staff and students, is quite worrying in lots of ways.  

One of the biggest worries is that there does not appear to be any hard evidence that Wi-Fi is actually safe to use. The teachers are not attempting to question the evidence; they are asking for a scientific investigation to be carried out. In my naivety, I had always thought that the introduction of such technology was done after exhaustive studies into what effect of it might be. But, it appears not. I imagine that the problem nowadays is that anybody asking whether or not a piece of equipment that you can buy over the counter is safe to use would be seen as a Luddite who is intent on holding up the march of progress.
