Health information

Health information for passengers

The X-rays at the security check at Zurich Airport do not affect passengers' health.

However, passengers with pacemakers should not go through the metal detector arch. Before flying, pregnant women should follow their airline's recommendations with regard to the week of pregnancy.

Health-related information

Hand baggage X-ray equipment

The amount of radiation during the hand baggage check is well below the permitted limit as per the Ordinance on Radiological Protection of the Federal Office of Public Health. The amount of radiation is very low, even for frequent flyers.

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 rays emitted by baggage X-ray equipment do not have any radioactive effect on food, medications or other materials and do not alter them. The screening does not have any negative effect on laptops, notebooks or mobile phones.

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. 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 sensitive pacemakers may be disrupted.

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 do not pose any health risks.

Risk of thrombosis/thrombosis injections
Extended sitting during a flight increases the risk of thrombosis. If you use injections to prevent thrombosis, we kindly ask you to dispose of the syringes correctly and not to deposit them unprotected in waste receptacles at the airport or on the aircraft. For correct disposal please use the protective cover provided with the syringe, dispose of the syringe in an empty, closable container (e.g. empty PET bottle) or hand in the syringe at a pharmacy at the airport. 


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.
