Airport X-rays are a concern for many travellers with laptops and other electronic devices. While X-rays can penetrate solid matter, they do not affect hard drives any more than ordinary visible light. In fact, X-rays are not capable of damaging your laptop or erasing its hard drive. However, it is important to take precautions to protect sensitive information, such as encrypting important files or using the BitLocker Drive Encryption tool. Additionally, some airport X-ray scanners can damage undeveloped film by causing fogging. Therefore, it is recommended to request a hand inspection for items containing film.

What You'll Learn
X-rays won't harm hard drives
X-rays will not harm hard drives. Hard drives are only sensitive to magnetic charges, and X-rays are not magnetically charged. The magnetic flux densities used in hard drives with modern evaporated or plated media are fairly high, and the shielding of the case, along with the distance from the magnetic source, makes it unlikely that the focus coils or power supply of an X-ray generator would have much of an effect.
X-ray machines at airports are very well-shielded, and X-rays should not mess with magnetic media. X-rays are essentially beta radiation or an electron originating from the electron shell. They are atomic radiation, not nuclear radiation, and they are produced in vacuum tubes. Old CRT TVs produced X-rays, but at a very low, harmless level.
While X-rays can harm highly sensitive photographic film, they will not damage flash media or optical discs. Computers, laptops, and the components within them are not sensitive to X-rays and are not damaged when sent through an X-ray machine. Flash media are not damaged when going through an X-ray, and floppy diskettes are only sensitive to magnetic charges, so taking them through an X-ray will not damage the drive.
However, it is important to handle all electronic devices carefully when placing them on a conveyor belt. There is a risk of damaging equipment by dropping it onto a surface. It is also recommended to back up all data on your computer before travelling by air.

Magnetic fields from conveyor belts can
X-rays are not known to damage hard drives. However, the electric motors used for conveyor belts generate strong magnetic fields that can erase or corrupt magnetic media. The magnetic fields produced by neodymium magnets, for example, are strong enough to erase or scramble data stored on magnetic media. Since hard drives store their data on magnetic media, similar results can be expected.
Magnetic fields can affect magnetic storage media such as audio cassettes, VHS tapes, and credit cards. The coercivity, or resistance to being demagnetized, of these materials is typically in the 500-1000 Oersted range, which is lower than the field produced by a magnet. Hard drive manufacturers have been improving the coercivity of hard drive platters to increase storage capacities, so newer hard drives are likely to have higher coercivity.
While it is challenging to wipe a hard drive using magnets, it is not impossible. Some older types of magnetic storage media can be erased with neodymium magnets. Additionally, large magnets placed on both sides of a running hard drive have been shown to keep the files on the drive intact. However, this does not mean that all combinations of magnets and erasure methods will be ineffective.
To ensure complete data erasure, physical destruction methods, such as shredding, or using degaussing machines that produce strong alternating magnetic fields, are more reliable. When travelling with sensitive equipment, it is advisable to take precautions such as encrypting important files or using encryption tools like BitLocker Drive Encryption.

X-rays can damage undeveloped film
To avoid damage to undeveloped film when passing through airport security, it is recommended to request a hand check or manual inspection. This involves asking a TSA agent to inspect the film by hand, rather than passing it through an X-ray machine. It is also suggested to pack film in a clear plastic bag and remove it from carry-on luggage at the security checkpoint. Additionally, marking the film with a "Do Not X-Ray" label can help to ensure it is not exposed to radiation.
It is important to note that the risk of damage from X-rays is specific to unprocessed or undeveloped film. Processed or developed film is not sensitive to light and therefore not susceptible to damage from X-rays. However, it is still recommended to take precautions when travelling with any type of film to ensure its safety.
Furthermore, while X-rays may not harm hard drives, it is crucial to handle electronic devices with care when travelling. Sensitive information stored on laptops or other devices should be protected through encryption or password protection. Additionally, the electric motors used in conveyor belts can generate strong magnetic fields that can potentially affect magnetic media. Therefore, it is advisable to remain cautious and attentive when placing electronic devices on conveyor belts at airport security.
In summary, X-rays can damage undeveloped film, and it is essential to take precautions when travelling with film to avoid potential damage. Additionally, while X-rays themselves may not harm hard drives, other factors in the airport security process may pose risks, and it is important to remain vigilant in handling electronic devices and protecting sensitive information.

X-rays can't damage flash media
X-rays cannot damage flash media. Flash media is not sensitive to light and is therefore not damaged when going through an X-ray. Flash media is also not affected by the electromagnetic field (EMF) emitted by the X-ray machines.
X-ray machines used in airports are typically fluoroscopes, which operate at lower energy levels than traditional X-ray machines. While these X-ray machines can image soft materials like plastic explosives, they do not emit enough radiation to damage electrical equipment or data.
However, it is important to note that X-rays can damage undeveloped film. High-energy X-rays can fog film and damage photos that have not been developed or processed yet. Additionally, some new X-ray machines with higher EMF output can streak standard black-and-white and color chrome and negative films.
While X-rays themselves do not harm flash media, it is recommended to back up all data on electronic devices before travelling by air. Physical damage from mechanical and thermal shocks during an accident or vibration on the plane can potentially cause data loss.
In summary, X-rays from airport security scanners are generally safe for electronic devices and flash media. However, it is always a good idea to back up important data before travelling and take precautions to protect sensitive equipment when passing through security checkpoints.

X-rays can't damage floppy diskettes
X-rays cannot damage floppy diskettes. While X-rays can penetrate solid matter, they will not harm electrical equipment or erase hard drives. Laptops, flash drives, and other electronic devices are also safe from X-ray damage.
Floppy diskettes are only sensitive to magnetic charges, and X-rays are not magnetically charged. Therefore, passing a floppy diskette through an X-ray machine will not damage the drive or the data stored on it. This has been confirmed by multiple sources, including a study published in PubMed, which found that airport X-rays had no effect on the data stored on floppy disks.
However, it is important to note that X-rays can damage undeveloped film. The electromagnetic waves produced by X-ray machines can fog or streak certain types of film, including standard black-and-white and color chrome films. As a result, some airports may offer hand inspections of film upon request.
Additionally, while X-rays themselves are not a concern, it is important to handle electronic devices with care when travelling. Damage is more likely to occur from dropping a device onto a hard surface than from sending it through an X-ray machine. Furthermore, electric motors used for conveyor belts can generate strong magnetic fields that can erase or corrupt magnetic media. Therefore, it is recommended to back up all data before travelling and to never leave electronic devices unattended.
