The word 'radiation' is closely associated with illness and cancer, but in fact radiation is emitted by most things, including humans and light. Some radiation is harmful, but most of it is not.
To operate, 5G makes use of a range of high frequencies which produce shorter waves, including millimetre waves (mmWaves). These fall into the spectrum of non-ionising radiation.
This non-ionising radiation at its worst only causes cells to vibrate, which can be experienced as heat; it doesn’t change the structure of a cell or cause lasting damage. Compliance with the ICNIRP guidelines ensures that there is no adverse impact on the health of those using mobile phones or living in communities where base stations, or masts, are located.
Ionising radiation from gamma rays, x-rays and ultraviolet (UV) rays can cause lasting damage to cells. That is why x-ray technicians who are repeatedly exposed to ionising radiation wear protective clothing, and why people wear sunscreen to protect themselves from UV rays. This is different to non-ionising radiation.
