The uncertainties regarding the link between electromagnetic fields and human health are a source of confusion for electric appliance manufacturers and have in some cases led to inconsistencies in product safety standards.
Induction-heating stoves emit electromagnetic fields within the same frequency band as video display terminals, which commonly take the form of computer screens.
Since 1993, member firms of the Japan Electronics and Information Technology Industries Association have voluntarily lowered the electromagnetic field exposure limits on their VDTs to levels to 0.25 milligauss at frequencies between 2 kHz and 400 kHz.
