The international guidelines recommended by the UK Health Security Agency (UKHSA), published by the International Commission on Non-Ionizing Radiation Protection (ICNIRP), provide protection for the population as a whole. As research continues to reduce uncertainties in science, people may wish to consider reducing their exposure levels.

The highest public exposure from radio wave sources arises from mobile phones when they are used for voice calls where the device is held close to the body.

Measures to reduce exposures from mobile phones have been recommended by the , which were accepted by government.

The main advice was:

• excessive use of mobile phones by children should be discouraged
• adults should be able to make their own choices about reducing their exposure should they so wish, but be able to do this from an informed position

Measures that can be taken to reduce exposure include:

• moving the phone away from the body, as when texting, results in very much lower exposures than if a phone is held to the head
• using a hands-free kit, keeping calls short, making calls where the network signals are strong
• choosing a phone with a low specific energy absorption rate (SAR) value quoted by the manufacturer

Exposures from devices held further away from the body such as wireless-enabled laptop computers, and transmitter masts in the community are very much lower than those from mobile phones and UKHSA considers that community or individual measures to reduce such exposures are unnecessary.
