X-ray scanners: safe or not?
X-ray scanners at airport security are generally considered safe for laptops. X-ray scanners use live imaging to check bags and create images by capturing the shadows of objects that don't let X-rays pass through them. While X-rays can damage biological tissue in large doses and with frequent exposure, they do not affect electronics in any significant way. This is because electronics are not made of biological tissue and do not have DNA that can be harmed.
However, there have been rare reports of laptops being damaged by airport X-ray scanners. Some people have claimed that their laptop's hard drive was fried or that they experienced issues with their laptop's functionality after going through airport security. It is important to note that these cases are uncommon and may be due to other factors, such as the laptop being wanded with a metal detector without the owner's knowledge.
To ensure the safety of your laptop, some manufacturers recommend hand inspection instead of X-ray scanning. This is because X-ray machines in major international airports often have additional features, such as metal detectors, that can damage the hard drive of a laptop. A hand inspection can also provide a more thorough security check.
Additionally, it is recommended to keep your laptop in its own tray when passing through airport security. This is because laptops can shield other items from view, and scanning them separately allows security officials to view the internal components and ensure that no dangerous objects are concealed. In some cases, you may be asked to turn on your laptop to prove that it is functional.
Overall, while X-ray scanners at airport security are generally considered safe for laptops, there are rare instances of potential damage. To minimize the risk of any issues, it is advisable to follow the recommendations of your laptop's manufacturer and the instructions provided by airport security staff.

Metal detectors: a threat to laptops?
Airport security has become increasingly stringent since the terrorist attacks in the US on 11 September 2001. Travellers are now accustomed to the request to remove laptops from bags before passing through security. But what dangers do airport security measures pose to laptops?
X-ray scanners are commonly used to check bags at airport security. These machines use live imaging to check the contents of bags. They are harmless to laptops, as X-rays are simply a form of light, and laptops are impervious to all forms of light. X-rays can be used to calculate the density of objects and deduce what they are made of. Laptops block X-rays, so they show up as dark objects on the scanner image.
However, metal detectors pose a greater threat to laptops. Metal detectors emit strong magnetic pulses, which can wipe hard drives. Therefore, it is recommended to avoid taking laptops through metal detectors. Hand inspection of laptops is also preferable to X-ray scanning, as multiple trips through an X-ray scanner may cause data loss or permanent hardware failure.
Some travellers have reported issues with their laptops after passing through airport security. One traveller reported that their laptop's hard drive was "fried" after going through airport security, while another reported that their laptop's screen was distorted. Another traveller claimed that their laptop's internal Wi-Fi sensor was damaged by an X-ray scanner, causing issues with Wi-Fi reception.

Hand inspection: the best option?
While some sources claim that airport X-ray scanners cannot damage laptops in any significant way, there are numerous reports from travellers who have experienced issues with their laptops after airport security. Some travellers have reported that their laptop's hard drive was "fried" after going through airport security, while others have reported distorted screens, and poor Wi-Fi reception.
It is important to note that X-ray machines do not use magnets or magnetic forces, and therefore cannot damage the magnetic media used by hard drives to store data. However, metal detectors and metal wands used by airport security emit strong magnetic pulses that can erase hard drives.
To avoid potential damage to laptops, some travellers suggest requesting a hand inspection. Hand inspections can provide peace of mind, especially for those who are concerned about potential damage to their devices. Additionally, hand inspections ensure that laptops are not exposed to any form of radiation, no matter how minimal.
However, it is worth considering that hand inspections may not be as thorough as X-ray scanning, and may not always be granted by airport security. X-ray machines in major international airports are often equipped with advanced technology for bomb detection, making them a preferred method for airlines.
Ultimately, the decision between X-ray scanning and hand inspection depends on individual preferences and risk assessment. While X-ray scanning is generally considered safe and efficient, there are rare reports of potential damage to laptops. Hand inspection may offer a safer alternative, but it may not always be feasible or as comprehensive.

Airport security: pre and post 9/11
Airport security has changed significantly since the terrorist attacks of September 11, 2001. Prior to 9/11, airport security was relatively relaxed. Individuals could arrive at the airport just minutes before their flight, keeping their shoes, coats, and belts on as they walked through a simple metal detector. No boarding pass or ID was required to go to the gate, and knives with 4-inch blades were permitted on planes. Carry-on bags were scanned by private companies hired by the airlines, and there were no restrictions on liquids, gels, or aerosols.
In the aftermath of 9/11, the Transportation Security Administration (TSA) was established to safeguard the nation's transportation systems and prevent future attacks. The TSA was created as part of the Department of Homeland Security, which was formed to address various security concerns, including terrorism prevention, law enforcement, and border security.
One of the key changes implemented by the TSA was the requirement for all passengers to undergo screening by federal officials. This included enhanced screening of carry-on and checked baggage, with 100% of checked baggage being screened for explosives. Wait times at security checkpoints increased as authorities conducted more thorough searches of passengers and their baggage.
Additionally, new identification requirements were introduced. The REAL ID Act, passed by Congress in 2005, established minimum security standards for state-issued driver's licenses and identification cards. Individuals must now present a REAL ID-compliant license, passport, or other federally accepted identification to board domestic flights.
Other security measures have also evolved over the years. For example, TSA PreCheck® was introduced in 2013 to provide expedited screening for known and trusted travelers. The TSA has also invested in advanced imaging technology and explosives trace detection systems, improving pat-down procedures, and enhancing screening requirements for select passengers at international and domestic airports.
While airport security has become more stringent since 9/11, it is worth noting that X-ray scanners used to inspect luggage are unlikely to damage electronic devices such as laptops. These scanners utilize ionizing radiation, which can harm biological tissue in large doses, but electronics are not made of biological tissue and are impervious to all forms of light, including X-rays.

The future of airport security: AI systems
Airport security scanners use X-rays to create live imaging and check passengers' bags. While ionizing radiation in large doses and frequent exposure can harm biological tissue, electronics are not made of biological tissue and are impervious to all forms of light, including X-rays. Therefore, airport X-ray scanners cannot damage laptops or other electronic devices in any significant way.
In recent years, AI-based systems have been increasingly adopted by airports worldwide to enhance safety and improve operational efficiency. AI technology helps address security issues by providing real-time information and alerting operators to threats as they arise, enabling faster response times. AI-powered solutions like Scylla transform passive cameras into proactive security systems for real-time recognition of security threats.
AI systems can also be used for intelligent access control, distinguishing between legitimate and unauthorized visitors. Biometric access control, such as facial recognition, is more secure than swipe cards, which can be lost, stolen, or borrowed. If an unauthorized entry is detected, the system can provide operators with real-time alerts.
AI is also being used to enhance threat detection at security checkpoints, with potential deployment in international airports by 2025. Machine learning techniques are used to automatically analyze data for threats, including explosives and firearms, while ignoring non-dangerous items. This streamlines security checks and increases accuracy, speeding up the screening process.
AI-powered systems are expected to play a significant role in enhancing international security checks, with airports in Europe, the Middle East, and Asia leading the way in testing these technologies. As AI continues to evolve, it will likely become a standard feature of airport security, revolutionizing the future of air travel.

Frequently asked questions
Airport security scanners use X-rays to scan luggage and bags. X-rays are generally considered safe for laptops. However, some people have reported issues with their laptops after passing through airport security, such as distorted screens, internal WiFi sensor damage, and data loss. Therefore, it is recommended to request a hand inspection for your laptop to avoid potential damage.
Airport security scanners use X-rays to create images of the contents of your luggage. X-rays are produced by accelerating electrons from a copper cathode to a tungsten anode through a voltage drop. The collision between the electron and the anode results in heat and high-energy photons, known as X-rays. These X-rays are then directed towards the object being scanned, and an image is created based on the shadows of objects that block the X-rays.
Some airports use advanced 3D scanning technology, allowing travellers to keep their laptops inside their bags during security screening. Additionally, metal detectors are commonly used to detect weapons or other illegal objects. These metal detectors do not emit X-rays but rely on non-ionising radiation or lower-energy millimetre waves to scan passengers.
