EMFs Explanation  During recent years, questions have been
raised about the possible health effects of 60-Hertz (power
frequency) electric and magnetic fields (EMF), which are found
wherever you have electricity.  EMFs are present wherever
electricity flows - around appliances and power lines and in
offices, schools and homes. Most, but not all, childhood studies
have reported a weak association between estimates of
residential magnetic field exposure and certain types of
childhood cancer. Worker studies have shown mixed results. Given
the uncertainty of the issue, the media and scientific
communities have been unable to determine that EMFs affects our
health nor have they established any standard or level of
exposure that is known to be either safe or harmful.  Many
researchers believe that if there is a risk of adverse health
effects from EMF, it is probably low, but warrants further
investigation. Recent concern focuses on exposure to magnetic
fields rather than electrical magnetic fields.  A number of res
