Please note the vaccination recommendations for your destination. Exposure to the X-rays at the security check at Zurich Airport does not have any significant effect on passengers.
However, passengers with pacemakers should not go through the metal detector arch. Pregnant women should follow their airline's recommendations.
We recommend that you enquire about epidemics and infectious diseases in your destination country. Vaccination recommendations and other tips are available via the relevant links.
Hand baggage X-ray equipment
Passengers passing through the X-ray baggage check are not exposed to any significant amount of radiation. Even for frequent flyers the effect is far weaker than for the security staff who are constantly in the vicinity of the equipment. The permitted dose for employees is well below that specified in the EU directives.
During the flight, each passenger is continuously subject to natural high-altitude radiation. This is several times higher than the maximum possible radiation dose received during the baggage check. The radiation dose potentially received by a passenger during the baggage check corresponds roughly to that experienced during two minutes at cruising altitude during a trans-Atlantic flight.
The rays emitted by baggage X-ray equipment do not have any radioactive effect on food, medications or other materials and do not alter them. Laptops, notebooks and mobile phones are not adversely affected by being X-rayed.
Metal detectors in the arch
When a person passes through the arch, an extremely low dose of electro-magnetic radiation is generated. This cannot be perceived by humans.
Measurements conducted by the supervisory authority have confirmed that the values are well below the statutory immission limit. This applies both to checked passengers and to the staff working permanently at the metal detectors. Based on the current level of knowledge,electro-magnetic fields do not, therefore, pose any risk. Passengers with pacemakers should exercise caution, however. They should not pass through the arch, as the malfunction limit of sensitive pacemakers may be exceeded.
Travelling when pregnant
Ask your airline directly how late into your pregnancy you are allowed to fly. The guidelines vary according to the airline. In some cases you may require a doctor's certificate. Security checks carried out with metal detectors (magnetic wands) do not pose any health risks.
