Yet more worry making!
Yet another attempt by the worried masses to find something to get hept up about. I work in an institution which has the pleasure of having probably the most dense coverage of any wireless network in an academic institution. I can only name one room where I can't get access now, but that's a very obscure room in itself.
I also happen to have worked in microwave communications for many years and have had the pleasure of being exposed to the maximum prescribed dosage of non-ionising radiation for a non-certified worker. Of course I can say "never did me any harm" because that was three years ago and with the nature of non-ionising radiation I would have to be dead by now or nothing.
I've also spent a substantial sum of money to organise a training course on the subject with the Health Protection Agency. I admit without a PhD in biophysics I am slightly disadvantaged, but it was all clearly explained to me and I understand the science of non-ionising radiation. I also was able to meet with a Greek scientist who studied the effects of close contact with Gaussian RF energy in mice, who after many years determined that he could find no threat only that there was a difference in collagen in female mice with high exposure.
I've measured my mobile with very expensive apparatus and accordingly in a poor reception area I would need 6 hours of continuous usage to reach the maximum safe limits. WiFi power is very small compared to the power that those of us who have worked in the RF industry are exposed to and I think that we would have noticed if there had been any correlation.
I have also met a short Hungarian man who once helped test radar systems by holding a florescent bulb up in a field to see if it lit. He said non-ionising radiation burns hurt in a very painful and unusual way, but he's in his 50s now and is healthy.
After all, a specialist workforce, working for more than the past 30 years has been variously exposed and no one has noticed anything with them.
Societies ills cannot be blamed on technology so easily:
