or animals? No, there's no evidence that microwaving food alters its composition or has any detrimental effects on living beings when microwaved items are eat.
MICROWAVES used in microwave ovens oscillate at 2450 million cycles per second (MHz). On the frequency spectrum , that region is located at the lower failure of the radar band, slightly above the frequencies used for UHF (ultra-high frequencies) TV channel, and safely in the NON-ionizing region. However, it is important to facts: Although microwaves do not carry adequate energy to be ionizing, they can be unsafe.
If microwaves can cook a piece of beef, these waves will also hold the same effect on human tissue if it is exposed to giant enough intensities for a long ample period of time. Certain body organs are extremely sensitive to this thermal effect. "Thermal" means warmth. Thus, it is the heat produced by a hot stove that cause the careless cook to utter a sudden unsavory expletive. Likewise, it is the grill generated by the microwaves that creates the risk in this armour.
Inasmuch as the significance for humans of repeated exposure to low levels of microwave radiation is still unformed, there is adequate evidence to warrant certain commonsense precautions:
Stay at lowest possible an arm's length away from an operating microwave oven
Do not operate an oven when it is empty
Do not operate an oven if the door will not close properly or is within any way undermined
Never tamper with the sanctuary interlock switches or the fuse
