They would get warm…and then hot…and then very hot…and then they would die. But if you only zapped them for a few seconds…it would just feel like a pleasant warming sensation. Unlike heating through infrared radiation (which is how the sun or a fire would heat you) microwave radiation would heat you from the inside, areas where you have more water stored like muscles and fat would warm fastest. My grandfather served in the Korean War and he once told me that they’d actually stand in front of microwave antennas to warm themselves on wet, cold nights. He lived to be 92 years old so…I guess it’s not /always/ dangerous.
