Is wireless internet hazardous to your health?

Lakehead University in Ontario has decided against installing campus wi-fi because of health and security concerns:

The safety of chronic, long-term exposure to electromagnetic energy, of which radio waves are a part, is a hotly contested scientific subject. Researchers have conducted hundreds of studies assessing the health impacts of this form of energy, studying not only radio waves, but related topics, such as microwaves and the electromagnetic fields around electric wiring.     …

    With the profusion of cellphone towers, wireless networks and electricity using electronic devices, exposure levels are rising rapidly across the globe.

    But most studies have been unable to prove conclusively that common, everyday exposures are a health hazard. In response, regulatory bodies around the world have usually concluded that there is no reason for public concern.
