Recent years have seen a significant increase - in terms of both number and variety - of electrical, magnetic and electro-magnetic fields used for various reasons. The sources include radio-telephonic antennae, computer and television screens, radar etc. The increase of these sources, and their increasingly frequent usage, has resulted in the exposure of the population, both working and civil, to more intense electric magnetic and electro-magnetic fields than usually present in nature. In the airport environment, the equipment which create electro-magnetic fields are essentially:
- cellular telephone stations;
- the radio transmission antennae mobile network;
- radar equipment.
At the Milan airports, specific mapping of electro-magnetic field values has been carried out, which has highlighted the level of compliance with the parameters and the thresholds established for the protection of human health.
Management of radio-active packages
SEA is currently the only airport manager in Italy to have received from the Ministry for Economic Development the highest authorisation level (Category A clearance in accordance with Legislative Decree 230/1995) for the movement and temporary storage of packages containing radioactive materials in transit at Malpensa airport, meeting all of the difficulties imposed by the regulation which, based on the nature of the material treated, was certainly not prepared to be adapted to an airport terminal. For Linate airport, already holding the clearance released in accordance with the applicable regulation, the conversion process into a similar authorisation has been initiated.
The actions carried out in collaboration with the technicians and officers within the various ministries and bodies, which over these years has supported and certified the work carried out, has resulted in the creation of:
- adapted rooms, with all applicable safety measures complied with, for the temporary storage of radioactive materials in transit;
- preliminary instrumental control processes on all radioactive packages entering the airport, both by air and by road;
- appropriate workplace procedures and radio-protection rules for all personnel involved in the movement and storage of packages;
- emergency verification and management procedures concerning irregular radioactive emissions.
All these actions today ensure that the Milan airport system manages in an entirely safe and regulatory compliant manner the transit of all radioactive goods (approx. 15,000 packages per year), which are forwarded also to hospitals, research centres and for industrial use.
