The WHO and the International Telecommunication Union (ITU) recommend that governments adopt the radio-frequency exposure limits developed by the International Commission on Non-Ionizing Radiation Protection (ICNIRP).
In the UK, the Government has adopted these exposure limits developed by ICNIRP and mobile network operators are required to operate within these guidelines.
