In contrast, visible light and longer-wavelength electromagnetic radiation, such as infrared, microwaves, and radio waves, consists of photons with too little energy to cause damaging molecular excitation, and thus this radiation is far less hazardous per unit of energy.
AM Radio broadcasting is the oldest technology to feature them. Naturally, they are part of the black body radiation spectrum from just about every object in space. For objects as cold as the cosmic microwave background, and as part of the cosmic microwave background itself, radio waves are the dominant emission.
