Radio Frequency radiation

Radio frequency radiation (RF radiation) and visible light are just two ranges of EMF on a broad spectrum of electromagnetic energy. The electromagnetic spectrum (EM spectrum) contains all known frequencies of EM radiation, from radio waves toward the lower frequency end, through the visible light spectrum, all the way up to gamma rays.

Radio frequency radiation is pretty low on the EM spectrum. Below it, we find extremely low frequency (ELF) radiation, such as what is emitted by the power lines and electrical circuits we use to supply electricity to our homes, then very low frequency (VLF) radiation such as computers/screens. Above radio frequency radiation, we find microwave radiation (MW radiation), which is what your microwave oven and mobile phone uses. Above MW is infrared (IR), such as that emitted by motion sensors or remote controls and then we have visible light.
Collectively ELF, VLF, RF and IR are known as non-ionizing radiation.

It is a long-held belief that the less energetic EM radiation in the lower end of the EM spectrum is less damaging than radio frequency radiation or MW, and x-rays are more damaging than ELF, VLF, RF and MW. This is why criteria for safety standards are different in each range of the EM spectrum.
However we know that even low-energy EMF can cause bodily damage.
A high-powered ELF field can deliver enough current to kill a person (such as a lightning strike or electric chair), while a person does not even feel a low-powered radio signal (such as a transmission from a baby monitor) that is composed of waves that can be a million times more energetic.
