Many travellers worry about sending their electronic devices through airport security scanners. The concern is understandable, given the high cost of such devices and the sensitive data they contain. While there are differing opinions on the safety of airport scanners for electronic devices, it is generally agreed that X-ray scanners will not damage computers or tablets because they do not contain any photosensitive materials. However, some sources suggest that multiple trips through an X-ray scanner may cause data loss or permanent hardware failure.

What You'll Learn
Computers are impervious to X-rays
X-rays are created by accelerating electrons through a potential difference and directing them onto a target material. The X-ray photons produced have varying levels of energy. When X-rays hit a material, some are absorbed, and others pass through. The higher the energy of the X-rays, the more they will pass through. X-rays can be used to create images of tissues and structures inside the body, as they can pass through skin and tissue but not bones.
Computers are dense with materials, and airport security may ask you to remove laptops from your bag so they can be scanned separately. This is because they may obscure other items in your bag. However, computers can safely pass through airport X-ray scanners. While X-rays can theoretically affect flash storage and cause data loss, the intensity of X-rays used in airport scanners is too low for this to occur.
Some people have reported issues with their laptops after passing through airport security. In some cases, hard drives have been fried, and laptops have experienced issues with WiFi reception. However, it is unclear whether these issues were directly caused by the X-ray scanners, as other factors could have contributed.
Overall, computers are designed to be impervious to X-rays, and passing through an airport X-ray scanner should not cause any damage.

Laptops can be damaged by X-ray machines
However, other sources claim that laptops cannot be damaged by X-ray machines. Laptops and other electronic devices do not contain any photosensitive components that could be affected by X-rays. They are impervious to all forms of light, including X-rays. While laptops use magnetic forces to store data, X-ray machines do not use magnets or magnetic forces, so they will not damage the laptop's data.
It is worth noting that some X-ray machines have additional features such as metal detectors, which may potentially damage a laptop's hard drive. Additionally, multiple trips through an X-ray scanner may cause data loss or permanent hardware failure.
To minimize the risk of damage, some travelers recommend having your laptop hand-inspected instead of putting it through the X-ray machine. Another suggestion is to turn on your laptop five minutes before reaching airport security, close the lid, and place it in your bag. This way, if airport security wants to inspect your laptop, you can simply open the lid and show them a glowing screen.

Laptops may need to be removed from bags
Laptops are dense with materials, and their battery and mechanical components can be too dense for X-ray scanners at most airports. This means that they may need to be removed from bags and placed in a separate bin for scanning. This is also done to ensure that the laptop does not block the X-ray view of other items in the bag, which could be potentially dangerous.
While some sources claim that X-ray scanners can damage laptops, others disagree. Laptops do not contain any photosensitive materials, so they will not be damaged by X-rays. However, X-rays can theoretically affect flash storage by erasing some cells, but the intensity of the X-rays used in airport scanners is too low for this to happen.
Some newer airport scanners can view carry-on luggage from multiple angles, eliminating the need to remove laptops from bags. These advanced scanners can determine whether something is being concealed, reducing the rate of tray handling and trimming the screening time per passenger.
If you are concerned about your laptop becoming scratched or damaged during the security screening process, you may want to consider purchasing a laptop bag that meets TSA criteria to save time.

Metal detectors may damage hard drives
While some sources claim that airport scanners cannot damage computers, there are reports of laptops being damaged by airport scanners. Laptops are dense with materials, and so airport security may ask you to remove them from your bag.
X-rays are a type of electromagnetic radiation with a shorter wavelength and a higher frequency than visible light. They are not radioactive and do not leave any residue. X-ray machines use a specific wavelength of light to operate, and hard drives store their data as magnetic media. While hard drives are not photosensitive and are impervious to all forms of light, including X-rays, some sources claim that X-rays can damage the hard disk, CPU, and memory in subtle ways.
Metal detectors, on the other hand, may damage hard drives. While hard drives are not affected by magnetic fields, they are delicate around and sensitive to magnets. Metal detectors may have magnetic strengths that are sufficient to affect hard drives. Therefore, it is recommended to avoid taking portable hard drives through metal detectors.
Some users have reported that their laptops were "fried" after going through airport security. However, others have claimed that X-ray machines in major international airports are now much more sophisticated and are primarily bomb detectors. Additionally, the intensity of the X-rays used in airport scanners is too low to cause data loss. Computers and tablets also do not contain any photosensitive components.
To avoid potential damage, some travelers recommend turning on your laptop five minutes before going through airport security and then closing the lid and placing it in your bag. This way, if airport security wants to check your laptop, you can simply open the lid and show them that it is functioning. Alternatively, you can request a hand inspection of your laptop, although this may not always be possible.

AI is transforming airport security
AI is revolutionising airport security, enhancing safety and improving operational efficiency. Airports have always faced a multitude of threats, from minor incidents to severe life-threatening security attacks. In recent years, security requirements have intensified, forcing airports to adopt advanced security measures. AI-based systems have emerged as a solution to tackle these challenges, with the potential to automate around 30% of aviation industry tasks.
AI is being leveraged to improve various aspects of airport security, including access control and passenger monitoring. Intelligent access control systems, utilising biometric facial recognition technology, distinguish between legitimate and unauthorised visitors, enhancing security and streamlining passenger flow. AI-powered computer vision models, such as Ultralytics YOLOv8, are employed during baggage screening to detect objects and ensure no items pose a security threat.
Additionally, AI is being used to enhance the accuracy of aircraft inspections and predictive maintenance. By utilising AI, inspections can be automated, improving efficiency and reducing the potential for human error. This technology is also applied to optimise fleet management, bringing precision to processes that were once time-consuming.
The global AI in the aviation market is expected to grow significantly, reflecting the increasing reliance on AI in the aviation industry. Governments and aviation hubs are investing in the development of AI systems to boost security and alleviate wait times. As AI systems improve with more data, they can analyse information and identify threats faster than humans, making them an invaluable tool in airport security.
While AI brings numerous benefits, careful consideration of challenges, such as system reliability, integration with existing technologies, and ethical concerns, is essential. A human-centric approach is key to harnessing AI's full potential while maintaining the values and standards that airports and travellers uphold.
