A Year of Wi-Fi Exposure Equals 20 Minutes of Cell Time

From Glenn Fleishman's Blog:

"Times of London offers some views on Wi-Fi’s dangers: Rather than analyze (or analyse) this article, I present two salient quotations.

Dr Michael Clark, of the [Health Protection Agency] says, “When we have conducted measurements in schools, typical exposures from wi-fi are around 20 millionths of the international guideline levels of exposure to radiation. As a comparison, a child on a mobile phone receives up to 50 per cent of guideline levels. So a year sitting in a classroom near a wireless network is roughly equivalent to 20 minutes on a mobile. If wi-fi should be taken out of schools, then the mobile phone network should be shut down, too—and FM radio and TV, as the strength of their signals is similar to that from wi-fi in classrooms.”

As somebody who sits beside my router all day, this has crossed my mind. I'm sure i'm getting a higher dose than I need to - i guess that the "take away" - knowing that the intensity drops with the cube of the distance. Everything i've seen says that ambient wireless is completely harmless. Thanks for the info.

get a least 2m away, much better than 1m.
