2015 Annual Report on Radiofrequency Electromagnetic Field Exposure Levels in Catalonia
- The Catalan Government presents the "2015 Annual Report on Radiofrequency Electromagnetic Field Exposure Levels in Catalonia", within the framework of the Radio-electric Governance project.
- During 2015, measurements have been performed in 1,945 sites, giving a total of 5,299 measurements performed. The urban sites where measurements have been performed include nurseries, preschools, primary and secondary schools, primary care centres, hospitals, nursing and care homes, public parks, and private homes, among others.
- The 5,299 measurements have been performed with 50 portable devices, and are added to the measurements performed by more than 300 monitoring equipment installed in 184 municipalities in Catalonia. These more than 300 devices continuously measure electromagnetic field levels and send the measurements automatically to a control centre owned by the Catalan Government.
Radiofrequency Electromagnetic Field Exposure Levels generated by mobile telephony antennae and other types of radio communication services (radio, television, Wi-Fi and WiMAX, among others) in Catalonia have been below the maximum levels defined in the regulations.
The Radiofrequency Electromagnetic Field Exposure Levels in Catalonia report is the result of the analysis of 4,180 measurements performed with 50 portable devices, and the thousands of measurements performed by more than 300 monitoring equipment installed in 184 municipalities in Catalonia.
During 2015, 1,114 urban locations have been measured around 111 municipalities of Catalonia, giving a total of 3,451 levels measured. The urban sites where measurements have been performed include nurseries (94), pre-schools and primary schools (189), compulsory secondary schools (80), primary care centres (95), hospitals (17), nursing and care homes (84), public Parks (111), and private homes (176), among others.
Thanks to the collaboration of the Catalan Rangers Corps, 1,848 measurements have been performed in the vicinity of 831 radio communication infrastructures in rural locations, in 2015. All measurements performed in rural locations in the vicinity of radio communication infrastructures are outdoors, at an approximate maximum distance up to 200 metres from these infrastructures.
The most restrictive maximum level of exposure in the regulations is related to the frequency used by the radiocommunication system. For example, for FM radio is 28 V/m, for mobile telephony is 41 V/m (for the 900 MHz band) and for Wi-Fi is 61 V/m.
The 50 portable devices measure the level of exposure from 100 kHz to 8 GHz (most restrictive maximum level is 28 V/m in this band). From the 5,299 measurements performed with the 50 portable devices, 5,258 are less than 5 V/m (of which 4,745 are less than 1 V/m); 31 between 5 and 10 V/m; 6 between 10 and 15 V/m; 4 between 15 and 20 V/m, and any above 20 V/m.
Recommendations regarding deployment of mobile phone antennae
Although all the levels measured by the more of 300 monitoring equipment and the 50 portable devices are below the maximum levels defined in the regulations, the report proposes some recommendations with respect to the deployment of mobile phone antennae, especially in urban locations.
It would be wise for local governments, mobile phone service providers and the representatives of citizens' associations to work more closely together in deploying mobile phone antennae, in order to create a climate of mutual trust.
The deployment of mobile phone antennae in urban locations should be as evenly distributed as possible.
When planning the deployment of mobile phone antennae, service providers must abide by the ALARA (as low as reasonably achievable) principle with respect to reducing the level of exposure to radiofrequency electromagnetic fields from antennae.
