In Kingston Ontario, two teachers unions want to have Wi-Fi turned off because they believe the signals post a health risk. Ashely Csanady writes in the National Post: “We’re concerned because Wi-Fi and microwave communications have not been determined to be safe, and we’ve never received any training about the hazards such as all the warnings that come with your cellphones or wireless devices.” A few years back there was a campaign to remove Wi-Fi from a school district north of Toronto. But thousands of studies and most reputable scientists suggest there’s little risk, primarily because the energy output of a router is so low. As Dr. Steven Novella of the NeuroLogica blog noted, From a basic science perspective, there is little plausibility to the notion that Wi-Fi radiation would have any health effects. The amount of energy that is absorbed by a person living in a Wi-Fi field is negligible — less than 1% of exposure from a typical cellphone and well below current safety levels.
