Limiting WiFi in schools: Canadian Medical Association Journal Medical Brief

February 17, 2012 (

The use of devices that emit nonionizing electromagnetic radiation such as cell phones and WiFi networks in schools should be limited because they constitute a workplace hazard, according to the Ontario Catholic Teachers Association. “Implementation of WiFi technology in schools will produce unprecedented exposure to microwave radiation of approximately 6 hours each school day, 5 days a week, for 40 weeks each year. This will be without any studies being done to determine the effects of either the short-term or long-term effects of this microwave exposure on adults as well as children,” the association stated in a position paper

The association also noted that “it is estimated that at least 3 percent of the population has an environmental sensitivity to the radiation that is emitted by these devices and, as a result, experience serious immediate physical/biological effects when exposed.” It recommended that WiFi access be confided to small areas such as libraries or cafeterias.
