There are no U.S. Federal standards limiting residential or occupational exposure to electric and magnetic fields (EMF) from power lines. However, some states have set standards for transmission line fields. Along with more information on EMFs, the National Institute of Environmental Health Sciences' EMF Q&A pamphlet (PDF, 65pp, 11.45Mb) provides information about state standards.
