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.
As someone else already posted, radio waves are a form of electromagnetic radiation. As such, they propagate at the speed of light. Theoretically they have an infinite range, but since they lose energy as the inverse square of the distance travelled, they become very weak quickly and are drowned out by more energetic local sources.
