Frederick Gilbert, president of Lakehead University in Thunder Bay, Ontario, Canada, has banned WiFi gear on his campus. Gilbert, a biologist by training, said he is concerned about possible health effects from exposure to even the low levels of RF radiation emitted by WiFi equipment. There is research showing that health effects from exposure to RF radiation (RFR) ranges from sleep disruption to genetic damage, although the effects from WiFi system emissions are probably at the relatively benign end of the range because the radiation is at such a low level. Current U.S. and Canadian health standards allow RFR exposure in the thousands of microwatts, but research in the past five years has begun to show effects from emissions measured in the nanowatts. "Once you get into the nanowatts range, you're getting into WiFi territory," said Cindy Sage, a principal in age EMF Design of Santa Barbara, CA. "And at least sleep disruption can be an effect of exposure and maybe a constellation of other health issues." Article
