Telecoms masts

Telecoms operators are responsible for ensuring that emissions from their radio masts meet the standards set down by the International Commission for Non-Ionising Radiation Protection (ICNIRP). The ICNIRP emission standards are recognised by the World Health Organisation, and are used within the European Union and other regions as a benchmark against which to measure radio-frequency transmissions.

During mast audits, measurements of emissions are taken and compared against the ICNIRP standards. The audit also examines safety processes and procedures that each operator has in place to secure their on-going compliance with their licence obligations, and to ensure the safety of the public, their own staff and others who may come into contact with the mast sites.

CICRA's most recent comprehensive audit of the mobile network operator's masts was carried out by consultants iWireless on CICRA's behalf in 2017.  All 274 mobile mast sites across the Channel Islands were examined and found to be well within the health and safety limits prescribed by the ICNIRP. In 2018, iWireless carried out a further audit, focussed on new masts and upgraded masts, together with surveying all masts in Alderney and Sark. During 2019, a further audit is planned, this will again focus on new and upgraded masts together with other masts on a sample basis.

The results of the most recent surveys for Jersey, Guernsey (including Herm), Sark and Alderney can be found here:

Interactive maps for each island allow you to locate individual mast sites and read the individual audit reports for each site.  You may also contact us for copies of the reports for any masts free of charge.
