Many people worry about their laptops being damaged by airport scanners. After all, laptops are expensive pieces of equipment, and the thought of an X-ray machine zapping your device is a scary one. However, the consensus is that airport scanners are safe for laptops. Laptops are dense with materials, so they need to be scanned separately from other items in your bag. But the X-rays used by airport scanners are impervious to electronic devices, and your laptop will actually be exposed to more background radiation while in flight than it will passing through the scanner.

X-rays are fine, but metal detectors may damage hard drives
X-ray scanners at airports are generally considered safe for laptops. Laptops are dense with materials, so they are asked to be removed from bags to avoid obscuring other items in the scan. However, they are safe to pass through the X-ray scanner and will not be damaged by the X-rays. This is because laptops do not contain photosensitive materials and are impervious to all forms of light, including X-rays.
However, there are a few reports of laptops being damaged by airport scanners. One person reported that their laptop's hard drive was "fried" after going through airport security, while another reported that their laptop's WiFi reception was significantly reduced. In these cases, it is unclear whether the damage was caused by the X-ray scanner or other factors, such as a manufacturing defect or physical handling by security staff.
While X-ray scanners are unlikely to damage laptops, metal detectors used at airport security may pose a risk to hard drives. Metal detectors use strong magnetic pulses to operate, which can potentially erase hard drives. Therefore, it is recommended to avoid taking laptops through metal detectors whenever possible. If a laptop must be scanned through a metal detector, it is essential to back up its data beforehand to prevent potential data loss.
To minimise the risk of damage to your laptop when passing through airport security, it is recommended to power it off as soon as possible after the scan to prevent overheating in suspend mode. Additionally, keeping your laptop in a TSA-approved bag with a dedicated laptop compartment can help ensure it goes through the X-ray scanner without issue.
In summary, while X-ray scanners at airports are generally safe for laptops, metal detectors may potentially damage hard drives due to their use of strong magnetic pulses. Taking precautions, such as using TSA-approved bags and powering off devices after scanning, can help minimise the risk of damage to your laptop when passing through airport security.

Laptops are dense with materials, so must be removed from bags
While it is rare, there have been instances where laptops have been damaged after passing through airport security. In some cases, laptop users have reported issues with their laptop's WiFi reception, while others have claimed that their laptop was "fried" by the airport scanner.
However, it is important to note that airport X-ray scanners are generally considered safe for laptops. Laptops do not contain any photosensitive materials and are impervious to all forms of light, including X-rays. The main reason for concern is not the X-ray scanner but rather the metal detectors used at airport security. These metal detectors emit strong magnetic pulses that can potentially erase hard drives.
To avoid potential damage, it is recommended to remove laptops from bags when passing through airport security. Laptops are dense with materials, and removing them ensures they do not obscure other items in the bag during scanning. TSA-approved bags are an exception, as they have special laptop compartments that prevent interference with other contents.
Additionally, it is advised to power off your laptop after passing through security to prevent overheating in suspended mode. While it may be inconvenient, it is also preferable to have your laptop hand-inspected by airport personnel rather than passing it through a metal detector.

Laptops are exposed to more radiation in-flight than during scanning
While some travellers have reported issues with their laptops after going through airport security, it is generally agreed that X-ray scanners will not damage laptops. In fact, laptops are exposed to more radiation in-flight than during scanning. This is because the Earth is constantly exposed to radiation, most of which comes from the sun, and the higher your altitude, the more radiation is around you. Therefore, when flying at 36,000 feet, your laptop will be exposed to the same amount of radiation as it would be during two chest X-rays. This is not considered a dangerous amount of radiation, but it does put the potential damage caused by airport scanners into perspective.
Laptops are dense with materials, so they show up as dark on X-ray scans, blocking the X-rays. Phones and tablets are also dense and can stay in bags because they are much smaller and won't obscure the view. Cameras and camcorders, however, use photosensitive materials, so it is recommended that these are removed from bags before scanning. Laptops, phones, and tablets, on the other hand, do not use photosensitive materials in their construction, so they will not be damaged by X-rays.
Although X-rays are safe for laptops, metal detectors and metal wands use magnetic forces and can pose a risk to hard drives. These detectors send out a strong magnetic pulse that can erase hard drives. Therefore, it is recommended that laptops are not taken through metal detectors or examined with metal wands.
Despite the general consensus that X-rays are safe, some travellers have reported issues with their laptops after passing through airport security. One traveller reported that their laptop had horrible Wi-Fi reception after going through an airport scanner, with only one bar out of five, and extreme buffering. Another traveller's laptop screen was distorted after flying, and they could not see the screen clearly. In one case, a laptop hard drive was "fried" after going through airport security, although this may have been due to a wand or metal detector rather than an X-ray scanner.

Laptops don't contain photosensitive materials, so X-rays won't damage them
Laptops and other electronic devices do not contain photosensitive materials, so X-rays won't damage them. Photosensitive materials absorb light energy and undergo a change in their physical or chemical properties when exposed to light. This can include changes in colour, structure, or electrical properties. While photosensitive materials are useful in imaging systems, from X-ray images to digital cameras, they are not used in laptops or other electronics.
Laptops are dense with materials, which is why airport security may ask you to remove them from your bag when passing through security. However, this is so they don't obscure other items in your bag, not because they are at risk of damage from the X-ray scanners.
While it is rare, some people have reported laptop damage after passing through airport security. In one case, a laptop's hard drive was "fried" after going through an airport X-ray scanner. However, a "Mac Genius" at the Apple store that fixed the hard drive said that it was unlikely that the X-ray scanner was the cause of the damage. Instead, the laptop may have been wanded with a metal detector, which can send out a strong magnetic pulse that can erase hard drives.
In any case, electronics are not made of biological tissue and do not contain DNA, so they cannot be harmed by ionizing radiation in the same way that biological tissue can. Furthermore, while magnetic data storage devices like hard drives are sensitive to magnets, they are impervious to all forms of light, including X-rays.
In fact, your laptop will be exposed to more background radiation while you are in flight than it will passing through the airport security scanner. So, while it is theoretically possible for airport scanners to damage your laptop, it is highly unlikely.

X-rays won't damage laptops, but metal detectors may cause overheating
X-ray scanners at airports are generally considered safe for laptops. X-rays do not use magnets or magnetic forces, so they will not damage your laptop or its hard drive, which is safe to put through an airport security X-ray scanner. Hard drives store their data as magnetic media, but airport X-ray machines use a specific wavelength of light to operate. Therefore, your hard drive will be unaffected by the airport X-rays, as it is not photosensitive.
However, it is important to note that some people have reported issues with their laptops after passing through airport security. For example, one person reported that their laptop's hard drive was "fried" after going through an airport X-ray scanner, while another person experienced issues with their laptop's Wi-Fi reception. While these cases are rare, they do occur, and it is essential to be aware of the potential risks.
Metal detectors, on the other hand, use strong magnetic pulses that can erase hard drives. Therefore, it is recommended to avoid taking your laptop through a metal detector whenever possible. If your laptop must go through a metal detector, make sure it is turned off and that the batteries are fully charged. This will help prevent overheating, which can occur if a laptop is left in suspend mode for too long.
Additionally, some airports may require a hand inspection of your laptop. In this case, it is essential to power down your machine as soon as possible after the inspection to avoid potential overheating issues. Overall, while X-rays are generally safe for laptops, metal detectors can pose a risk to the functionality of your device, and it is essential to take precautions to protect your laptop when passing through airport security.
