Security Scanners


Security scanners are deployed at Edinburgh Airport to help mitigate the threat from non-metallic improvised explosive devices. This reflects the Government’s current assessment of the risk to aviation in the UK.


All scanners currently deployed at Edinburgh Airport use Automatic Threat Recognition software (ATR). This ensures that passengers’ privacy is respected.

No image of the passenger’s body is created or stored. ATR replaces the need for a human reviewer, and means that the data from the scan is not used to create an image.

Instead, the ATR software uses the scan data to identify areas which should be checked with a targeted hand-search. This information is highlighted on a generic, anonymous figure.

All processing is done electronically, with no intervention by a human screener. Safeguards are in place to make it impossible to save, copy, or transfer data.

For further details on the deployment of security scanners in the UK, and the safeguards in place, including the Code of Practice for the use of security scanners, please see this website:

Not all passengers at Edinburgh Airport will pass through a security scanner, but those who are selected will be required to do so, or to undergo an alternative screening method (if the passenger opts out from being screened by the scanner).

This alternative will involve at least an enhanced hand search in private. The ‘enhanced hand search in private’ is a more extensive hand search, is conducted in a private room, and may involve the loosening and/or removal of clothing.

This alternative screening method will take significantly more time than passing through a security scanner and, as well as a hand search in private, potentially involves additional security processes (including the use of Explosive Trace Detection and Metal Detection technology). Passengers will be escorted to a different location in the airport from the main search area (e.g. a private search room).

This alternative offers comparable security assurance to being screened by a security scanner.


All security scanners currently deployed at Edinburgh Airport use millimetre wave technology.

The use of millimetre wave security scanners in airports is permitted under EU law (Regulation 1141/2011, amending Regulation 272/2009).

Millimetre wave security scanners use a very low power non-ionising form of electromagnetic radiation. The amount of electromagnetic radiation emitted by millimetre wave security scanners is many times lower than that emitted by a mobile phone.

Limits on exposure to electromagnetic radiation have been set by the European Commission to provide a high level of protection against any potential effects on the public. Millimetre wave scanners emit far less radiation than these limits. Safety studies have concluded that, at these levels and these frequencies, there are no known health effects.

Implanted electronic medical devices such as pacemakers, implantable cardioverter defibrillators (ICDs), CGM (Continuous Glucose Monitors) and neurostimulators

The Medicines and Healthcare products Regulatory Agency (MHRA) is the government agency which is responsible for ensuring that medicines and medical devices work, and are acceptably safe.

The MHRA are not aware of any cases where implanted electronic devices have been affected by security scanners. If you have an implanted pacemaker, ICD or neurostimulator you can safely use airport security scanners.

The CAA recommends that users of CGMs and other equipment such as diabetic pumps should not be worn within the scanner.

For further information relating to your own specific implanted device please contact your local cardiac centre or doctor.
