on its website that microwaves do produce electromagnetic fields, but they are the"non-ionizing radiation part of the electromagnetic spectrum and are not known to damage DNA or cells directly."there is no harmful radiation from microwave ovens"unless the door hinges, latch, or seals are damaged."
"The FDA also monitors appliances for radiation safety issues and has received reports of microwave ovens that appear to stay on -- and operate -- while the door is open," the agency says on its website."When operating as intended, microwave ovens have safety features to prevent them from continuing to generate microwaves if the door is open.
The WHO adds that, despite some misconceptions,"it is important to realize that food cooked in a microwave oven does not become 'radioactive.' Nor does any microwave energy remain in the cavity or the food after the microwave oven is switched off." "In this respect, microwaves act just like light; when the light bulb is turned off, no light remains," the agency says.
