Based on the evidence and expert advice, members of the public do not need to take any special steps to reduce exposure to the low levels of radio waves from Wi-Fi networks and equipment (e.g. as used in public settings), smart meters or mobile phone base stations. However, it is recommended to avoid non-essential use of mobile phones for voice calls amongst children; this is because exposures are higher when mobile phones are held to the head to make voice calls, though this is still within guideline levels.
