There are conflicting opinions on whether laptops can go through airport X-ray machines. Some sources claim that X-ray scanners can damage laptops by affecting flash storage and causing data loss. Others argue that the intensity of airport X-ray scanners is too low to cause any harm to laptops. Additionally, laptops are dense with materials, so they are typically removed from bags and scanned separately to avoid obscuring other items in the bag. While there are concerns about potential damage to laptop hard drives, it is generally accepted that X-rays themselves do not use magnets or magnetic forces and will not harm the laptop's hard drive. However, separate metal detectors or wands used by airport security may damage hard drives due to their strong magnetic pulses. Overall, while there are mixed opinions, many sources lean toward it being safe to put laptops through airport X-ray scanners.

What You'll Learn
Laptops are safe in airport X-rays
It is understandable to be concerned about the safety of your laptop when passing through airport security. After all, laptops are expensive pieces of equipment and often contain sensitive information. However, you can rest assured that, for the most part, airport X-ray scanners will not damage your laptop.
Firstly, it is important to understand that X-rays are a type of electromagnetic radiation, similar to visible light but with a shorter wavelength and a higher frequency. This increased energy allows X-rays to pass through objects like plastic, skin, and tissue, but not denser materials like bones or metal. While X-rays are a form of radiation, they are not radioactive and do not leave any lingering residue.
When it comes to your laptop, you may be concerned about potential damage to the hard drive or other components. Hard drives store data as magnetic media, but airport X-ray machines use a specific wavelength of light to operate, and your hard drive is not photosensitive. Therefore, it will not be affected by the X-rays. Additionally, computers and tablets do not contain any photosensitive materials, so they will not be damaged by the X-rays either.
While X-ray scanners are generally safe, there may be some rare instances where issues can occur. Some sources suggest that X-rays can affect flash storage by erasing some cells, which could potentially lead to data loss. However, the intensity of X-rays used in airport scanners is typically too low for this to occur. Nevertheless, it is recommended to shut down your laptop completely before passing it through the scanner as a precautionary measure.
One important precaution to keep in mind is to avoid taking your laptop through a metal detector or allowing it to be examined with a handheld metal detector wand. These devices use strong magnetic pulses that can potentially erase your hard drive. Always opt for the X-ray scanner instead. Additionally, some X-ray machines may have metal detector features, so it is advisable to request a hand inspection if you are concerned.

Metal detectors can damage hard drives
X-rays are a type of electromagnetic radiation, similar to visible light but with a shorter wavelength and a higher frequency. They are not radioactive or created by radioactive substances. Airport security scanners use live imaging to check bags and create X-ray particles. Computers and tablets do not contain any photosensitive materials in their construction, so they will not be damaged by X-rays.
However, metal detectors use electromagnetic induction, which can affect magnetic media such as hard drives. Metal detectors emit a strong magnetic pulse that can erase hard drives. While this is rare, it is possible.
To avoid any potential damage, it is recommended to remove laptops and tablets from bags before passing them through airport security. These devices are dense with materials and will be scanned separately to ensure they do not obscure other items in the bag.
While some people have reported issues with their laptops after passing through airport security, others have had no problems. It is generally considered safe to put laptops through X-ray scanners, as the intensity of the X-rays used is too low to cause any damage.

X-rays are not radioactive
X-rays are a type of electromagnetic radiation, similar to visible light, except they have a much shorter wavelength and a much higher frequency. An individual X-ray particle is just a photon, but it has more energy than a photon of visible light. This increased energy allows X-rays to travel through objects like plastic, skin, and tissue, but not enough to go through bones or metal.
X-rays are produced when electrons strike a target or when electrons rearrange within an atom. X-rays are commonly produced in X-ray tubes by accelerating electrons through a potential difference (a voltage drop) and directing them onto a target material (e.g., tungsten). The incoming electrons release X-rays as they slow down in the target (braking radiation or bremsstrahlung). The X-ray photons produced in this manner range in energy from near zero up to the energy of the electrons.
While X-rays are linked to a slightly increased risk of cancer, this risk is very small, and the benefits of X-rays far outweigh the risks. X-rays have been used in medicine for a long time and are considered very beneficial. Furthermore, the X-rays used in airport scanners are of such low intensity that they will not damage your laptop or other electronics.

Laptops must be removed from bags
Additionally, there are flammability concerns associated with laptop batteries. Given these concerns, placing laptops in separate bins for scanning is a precautionary measure to enhance safety.
Furthermore, while the likelihood is low, there is a possibility that airport X-ray scanners could damage laptops. This risk is due to the high-energy X-rays used, which have sufficient energy to pass through plastic and other materials. Although computers and tablets do not contain photosensitive materials, there have been rare reports of laptops experiencing issues after passing through X-ray scanners. Some travellers have reported issues with their laptop's hard drives being erased or fried, while others have mentioned problems with wifi reception and screen display after airport scanning.
However, it's important to note that the intensity of X-rays used in airport scanners is typically too low to cause data loss in solid-state drives, SD cards, or USB thumb drives. Additionally, laptops are not expected to be removed from their sleeves or cases during security screening, although some sources suggest removing metal closures to avoid any potential interference with the scanning process.

X-rays can affect flash storage
X-rays are a type of electromagnetic radiation, similar to visible light, but with a shorter wavelength and a higher frequency. They are not radioactive and do not linger, so their effects are limited to exposure. X-rays can pass through materials like plastic, skin, and tissue, but not bone or metal.
X-rays are commonly used in medical imaging, such as CT scans, and in airport security scanners. While X-rays are generally safe for electronic devices, there are some concerns about their potential impact on flash storage.
Flash memory is a type of non-volatile memory commonly used in electronic devices, such as laptops, tablets, and USB thumb drives. It is known to be sensitive to radiation, and X-rays can cause bit errors and data corruption in these storage devices. During X-ray inspection and CT scans, flash memories are exposed to polychromatic X-rays, and the absorbed dose is known to cause bit errors. Increasing the tube voltage, tube current, and X-ray beam size leads to more byte errors and data corruption.
However, the intensity of X-rays used in airport scanners is very low, and computers and tablets do not contain any photosensitive components. Therefore, it is highly unlikely that airport X-ray scanners will damage your laptop's flash storage. Your device is exposed to more background radiation while in-flight than when passing through the scanner.
While there may be rare cases of laptop damage due to airport X-ray scanners, it is not a significant cause for concern. It is recommended to shut down your laptop completely before putting it through the scanner as a precautionary measure.
