There is much debate about whether this magnetic field is hazardous, but several authoritative sources, including the Food and Drug Administration, have noted that small children should avoid these electromagnetic fields. According to Mercola.com, Dr. David Carpenter, a Dean at the School of Public Health at the State University of New York, believes that ionic hair dryers produce an electromagnetic field that is about 200 to 400 Gauss, a level that can cause cancer in children.
