Electric and Magnetic Fields

On a daily basis, Canadians are exposed to electric and magnetic fields (EMFs) generated by household wiring, lighting, and electrical appliances such as microwave ovens, hair dryers, and toasters. In the workplace, common sources include computer monitors, photocopiers, fax machines, and fluorescent lights. Power lines and electric tools also emit EMFs. Some medical applications of EMFs include short-wave diathermy and magnetic resonance imaging (MRI).

During the last twenty years, the general public has become increasingly concerned about potential associations between EMF exposure and adverse health effects.

Health Canada has been taking part in the Next link will take you to another Web site International EMF Project, coordinated by the World Health Organization (WHO). The goals of this project are to verify reported biological effects from exposure to electromagnetic fields (EMF) and to characterize any associated health risks to humans.
