A nonprofit organization's discovery in March that the radiation emitted by some portable induction-heating cooking stoves greatly exceed international limits has raised questions about the products' safety and what is being done about it.

Though it has not been proved that exposure to electromagnetic fields is linked to health problems, including cancer, some experts are calling on the government and industry to take precautionary measures before science gives its verdict.

However, neither party seems eager to make attempts to limit electromagnetic field exposure from IH cookers, with authorities and manufacturers boasting of the products' safety, while saying it is the responsibility of the other party to boost awareness of possible risks.
