Microwave radiation between radio waves and visible light, visible light such as sunlight, we are bathed in every day; and usually use the radio to listen to the radio belongs to radio waves, so we do not have to be too nervous about microwave radiation, it is not imagined terrible.
Secondly, the heating principle of the microwave oven is to use microwave radiation to the food, so that the polar molecules in the food, such as water molecules produced a phenomenon similar to the friction, so that the water temperature rises, in order to achieve the purpose of heating.
That is to say, in addition to heating, microwave has no other harm to the human body
