Several sources of electromagnetic emissions related to air navigation instruments (surface radar, instrument landing system etc.) and ground-air and radio communication instruments have been identified at Venice Airport.
Several measurements of the electric fields carried out in the immediate vicinity of the airport were performed by the Veneto region's Environmental Protection Agency, with results showing that the electric field values are always abundantly below the 6 V/m, corresponding to the alert value/quality goal provided for by regulations. The airport operator also installed 6 units (4 stable and 2 mobile) to measure electromagnetic fields (EMF). The measurements are carried out on all the frequencies used by air navigation service systems and base stations for mobile telephony. Therefore, the data obtained by continuous monitoring allow a complete and exhaustive verification of electromagnetic fields. Quarterly statistics show full compliance with alert values/quality goals as provided for by decree DPCM of 08/07/2003. Investigations have shown that, in all the areas monitored, the detected electromagnetic emission values are within regulatory limits; particularly in external monitoring areas, the prevalent electromagnetic presence comes from systems for mobile phones and radio used in the aprons.
In addition, specific measurements (inside the SAVE building) were carried out to verify the exposure to the electromagnetic fields produced by the PAR (Precision Approach Radar) complex (located on the lagoon side of the landing runway). Measurements, performed with spectrum analyser and directional antennas with the purpose of identifying and isolating the PAR contribution, have shown that "The power radiated towards the SAVE operational complex from the radar installed by the runway varies on average between -20 and -30 dBm. Such power levels, coupled with a reduced beam interval of only 38 milliseconds, make the electromagnetic impact on the SAVE structure virtually negligible".
As it will not involve changes in the emission sources with respect to the current conditions, the impact of the envisaged scenario without intervention is therefore nil.
With reference to the scenario in 2021, the works described in the Master Plan, which are the subject of this assessment, do not involve the installation of new transmitting installations or the increase of the power of the existing installations, so the future situation will not be different from the current situation.
The impact of the Master Plan on the "ionizing and non-ionizing radiation" component in scenario in 2021 is therefore nil.
