The annual independent audit was carried out across the Channel Islands by consultants iWireless-Solutions Ltd and commissioned by the Channel Islands Competition and Regulatory Authority (CICRA).
'The audit is an important part of our work in ensuring that telecoms operators in the Channel Islands are meeting the conditions set out in their operating licence and historically all operators in the Channel Islands have worked well within the recommended guidelines,' said CICRA director for telecoms Tim Ringsdore.
'The governments of Jersey and Guernsey set the emissions standards required as part of those licences, and it is our job as the independent regulator to monitor those levels on a regular basis.'
Audits are conducted to ensure that emissions from radio masts, owned by the island telecom operators, meet the International Commission for Non-Ionising Radiation Protection (ICNIRP) standards.
ICNIRP emission standards are recognised by the World Health Organisation and are used within the EU and other regions as a benchmark against which to measure the safety of radio-frequency emissions.
This year's audit focused on new and upgraded masts together with other sites on a sample basis after a comprehensive survey of all 274 mast sites across the Channel Islands was conducted by iWireless in 2017.
iWireless Solutions is an independent company and a specialist system integrator and service provider with an extensive track record for deploying bespoke, high-capacity indoor and outdoor wireless systems.
The company also specialise in RF [radio frequency] Health and Safety and iWireless consultants have been advising major UK airports, telecoms regulators and businesses on emission safety matters for workers and general public.
'CICRA engaged iWireless Solutions to carry out regular audits of the mobile network sites in the Channel Islands, ensuring that all the sites meet the international standards on the safety of the emission levels,' said iWireless head of engineering Bachir Belloul.
'We use fully calibrated, industry-recognised measurement equipment and qualified engineers with over 20 years of experience to ensure our testing is repeatable and of the highest standard.'
Safety processes and procedures are analysed during the audit to ensure compliance with local health and safety legislation.
The results of the audit are published on the Competition Authority website www.cicra.gg, where interactive maps for each island allow the public to locate individual mast sites and read the relevant report for that location.
Copies of the reports can also be obtained free of charge.
The results of the 2019 audit should be available by the end of the year.
