It is a common concern that airport X-ray scanners may damage electronic devices such as computers, laptops, hard drives, and smartphones. While X-ray machines emit X-ray radiation, they do not damage or destroy electrical equipment or data. Hard drives store their data as magnetic media, and airport X-ray machines use a specific wavelength of light to operate. Therefore, unlike photo film, hard drives are not photosensitive and will not be affected by airport X-rays.

X-ray machines emit radiation but do not damage hard drives
X-ray machines emit radiation, but they do not damage hard drives. Hard drives are only sensitive to magnetic charges, and X-rays do not emit magnetic radiation. Therefore, they cannot harm hard drives or the data stored on them.
X-ray machines use a specific wavelength of light to operate, and hard drives are not photosensitive. While X-rays can damage undeveloped film, they do not affect hard drives or electronic devices.
It is important to distinguish between X-ray machines and metal detectors or wands used at airport security. Metal detectors and wands emit strong magnetic pulses that can potentially damage hard drives. Therefore, it is recommended to power down electronic devices completely before passing them through airport security.
While X-rays are generally considered safe for hard drives, there are rare instances where individuals have reported issues with their hard drives after passing through airport security. In some cases, this may be due to the device being wanded without the individual's knowledge or due to a faulty device. However, it is always a good idea to back up important data before travelling to avoid data loss in case of any unforeseen issues.
Additionally, it is worth noting that while X-ray machines at airports are not known to damage hard drives, they can affect other types of storage media, such as high-speed film or certain optical discs. These items may be more sensitive to radiation and can be damaged by the cumulative effects of multiple X-ray scans.

Hard drives are only sensitive to magnets, not X-rays
Hard drives are not affected by X-rays. They are only sensitive to magnetic charges. X-rays do not damage or destroy electrical equipment or data. Therefore, you can take a hard drive or computer with a hard drive through an X-ray without damaging the drive.
X-ray machines use a specific wavelength of light to operate. Hard drives store their data as magnetic media, so they are not photosensitive and will be unaffected by X-rays. X-ray scanners in airports are also very well shielded, and X-rays should not interfere with magnetic media.
It is important to note that while X-rays are generally safe for hard drives, metal detectors and wands used at airport security checkpoints can send out strong magnetic pulses that can potentially erase hard drives. Therefore, it is recommended to back up all data on your computer before travelling by air.
Additionally, while X-rays are safe for hard drives, they can damage other types of media, such as undeveloped film. High-speed film and multiple passes through X-ray scanners can increase the risk of damage.
In summary, hard drives are not sensitive to X-rays but only to magnets. X-rays do not have the capacity to damage or affect hard drives or the data they contain. However, it is always a good idea to take precautions when travelling with important data by backing it up and being aware of potential risks from other sources, such as metal detectors.

Metal detectors and wands at airport security may damage hard drives
X-ray scanners at airport security are generally considered safe for laptops and hard drives. Hard drives store their data using magnetic media, but airport X-ray machines use a specific wavelength of light to operate. Therefore, they are not photosensitive and will not be affected by the airport X-rays.
However, there have been rare instances where individuals have reported their hard drives being wiped clean or fried after going through airport security. While the exact cause is unknown, some have speculated that their devices may have been examined with a metal wand or metal detector, which sends out a strong magnetic pulse that can potentially erase hard drives.
To mitigate the risk of data loss, it is recommended that individuals back up all data on their computers before travelling by air. Additionally, turning your laptop off completely, rather than putting it in sleep mode, may also reduce the risk of any potential issues.
It is important to note that other electronic devices, such as MP3 players, cell phones, smartphones, and USB thumb drives, are also not expected to be affected by X-rays, unless otherwise stated by the hardware manufacturer.

X-ray machines can damage undeveloped film
X-ray machines emit a small amount of radiation that can fog and damage undeveloped film. The risk is higher with higher-speed films (ISO 800 and above) and multiple exposures to X-rays.
The X-ray machines used for carry-on luggage are less intense, but they still pose a risk, especially if your film is exposed multiple times during a trip. If you have a higher ISO film and are concerned that it may impact your images, you can request a hand inspection of your photographic film. Hand-checking a camera and film does not take much time and is the best way to keep your film safe.
Most TSA checkpoints state that film rated at 800 ISO or lower isn't likely to be affected by standard X-ray machines. However, the TSA and security agencies in most countries allow travellers to request a hand inspection of photographic film. To do this, approach the security checkpoint and politely request a hand inspection, explaining that you are carrying undeveloped film.
To avoid any risk of fogging your unprocessed film (including loaded cameras), always request that your carry-on be hand-inspected at the airport security checkpoint. Regulations and inspections vary by country, so some international airports may not honor this request.

X-ray effects on film are cumulative
Airport X-ray machines emit X-ray radiation, which can have a detrimental effect on certain types of film. This radiation can cause a unique pattern of damage, often manifesting as foggy or wavy lines across the film. The affected areas may exhibit reduced or obliterated shadow detail, with increased grain and greenish hues, particularly in color film. The impact can vary depending on the film's sensitivity, with higher ISO values being more susceptible.
The effects of X-rays on film are cumulative, meaning that each exposure to radiation adds to the overall damage. Multiple scans or prolonged exposure can lead to more significant and irreversible harm to the film. This is why it is crucial for photographers to be cautious and explore alternative options, such as requesting manual inspections or hand checks for their film equipment.
To mitigate the risks, photographers traveling with film are advised to use protective measures such as lead-lined film bags or lead pouches. However, it is important to note that while these bags can block standard X-rays, they may not be effective against the more powerful CT scanners found in some airports. As a result, hand-checking film rolls remains the safest option to prevent cumulative X-ray damage.
Additionally, keeping film insulated and maintaining reasonable temperatures are essential. Heat can also damage film, so storing it within jackets or multiple layers of clothing during travel can help regulate the temperature and minimize potential harm. By understanding the cumulative effects of X-rays on film, photographers can take the necessary steps to safeguard their equipment and ensure their film remains undamaged during airport security checks.
