Thumb drives, also known as USB drives, are a common way to store data. They are small, portable, and convenient, making them ideal for travel. However, some people may be concerned about the potential impact of airport security scanners on their thumb drives. Airport security scanners use X-ray technology to screen luggage and electronic devices for prohibited items. While X-rays are generally considered safe for electronic devices, there are some concerns about their potential impact on thumb drives and other storage media. Some people worry that the X-rays used in airport scanners may damage or erase data stored on thumb drives.

Airport X-ray scanners are unlikely to damage thumb drives
If you're travelling with a thumb drive, you may be concerned about putting it through an X-ray scanner at airport security. While X-rays can be used to create images that show the contents of your bag, they will not damage your thumb drive or its data.
X-rays are ionizing radiation, which means they have enough energy to knock electrons out of atoms, creating positively charged ions. While this can harm biological tissue and cell DNA, thumb drives are not made of biological tissue and do not contain DNA.
Thumb drives use transistors, which either allow electrical currents to pass through (representing a one) or prevent them from passing through (representing a zero). This is how data is stored, and it is impervious to all forms of light, including X-rays. While X-rays can theoretically affect flash storage by erasing some cells, the intensity of X-rays used in airport scanners is too low for this to happen.
Computers and tablets do not contain any components that are photosensitive to visible light or X-rays. You may be asked to remove laptops and tablets from your bag at airport security, but this is because they are dense with materials and could obscure other items in your bag.
The main reason you shouldn't worry about your thumb drive being damaged by airport scanners is that it will be exposed to more background radiation while in flight than it will receive when passing through the scanner.

Thumb drives use transistors to store data, which are impervious to X-rays
Airport X-ray scanners are designed to inspect bags and generate images of their contents. While these machines emit X-ray radiation, they do not damage or destroy electrical equipment or data. Computers, laptops, tablets, mobile phones, USB thumb drives, and other electronics are not affected by the low-intensity X-rays used in airport scanners.
Thumb drives, also known as USB flash drives, are data storage devices that utilize flash memory with an integrated USB interface. They were first offered for sale in late 2000 and have since become a common tool for storing, backing up, and transferring computer files.
The use of transistors in thumb drives is integral to their data storage capabilities. Transistors function as memory cells, either allowing or blocking electrical currents, which are represented as ones and zeros, respectively. This binary system enables the storage of digital data.
While X-rays can theoretically affect flash storage by erasing cells, the X-ray intensity in airport scanners is too low to cause any data loss in thumb drives. Additionally, computers and tablets do not contain any components that are photosensitive to light or X-rays. Therefore, thumb drives, which are based on transistor technology, are impervious to the X-rays used in airport security scanners.
It is worth noting that while airport X-rays are safe for thumb drives, other types of scanning technology, such as metal detectors, can potentially cause damage to electronic devices and data. It is always advisable to back up important data before traveling and to consult the hardware manufacturer's guidelines for specific recommendations or precautions related to X-ray exposure.

X-rays can affect flash storage by erasing some cells, but airport X-ray machines are too weak to do so
X-rays are ionizing radiation, meaning the photons they emit have enough energy to knock electrons out of atoms, creating positively charged ions. While this process can harm biological tissue, electronics are not made of biological tissue and are not affected by X-rays. Magnetic data storage devices, such as hard drives and floppy disks, use mechanical arms to read and write data magnetically, making them impervious to all forms of light, including X-rays.
Solid-state drives, SD cards, and USB thumb drives use transistors to allow or block electrical currents, which is how they store data. While X-rays can theoretically affect flash storage by erasing some cells, the intensity of X-rays used in airport scanners is too low for this to occur. Computers, laptops, tablets, and phones are not photosensitive to light or X-rays, so there is no risk of data loss when passing through airport security.
However, some sources suggest that airport X-ray scanners are not entirely safe for laptops. In rare cases, laptops have experienced issues with WiFi reception, internal components, and hard drive functionality after passing through airport security. It is important to note that these issues may be due to other factors, such as the magnetic fields emitted by metal detectors or vibrations during the flight.
Additionally, while airport X-rays are unlikely to affect modern hard drives, they can damage undeveloped film. High-speed films, such as those with ISO 800 or higher, are particularly sensitive to X-rays and may be fogged or streaked by the radiation. As a precaution, it is recommended to request a hand inspection for sensitive undeveloped film.
In summary, while X-rays have the potential to erase cells in flash storage, the X-rays used in airport scanners are too weak to cause any data loss. However, it is always a good practice to back up important data before travelling, as electronics are susceptible to various travel-related stresses and there is a slim chance of data loss during security checks.

Metal detectors and metal wands at airport security may emit strong magnetic pulses that can damage hard drives
X-ray scanners at airport security are used to create live imaging to check the contents of bags. While these X-ray machines emit X-ray radiation, they will not damage or destroy electronic equipment or data. Computers and tablets do not have any components that are photosensitive to light or X-rays.
However, metal detectors and metal wands at airport security may emit strong magnetic pulses that can damage hard drives. Metal detectors use electromagnetic induction, and a strong enough electromagnetic pulse can affect magnetic media, such as hard drives. While consumer-grade magnets are unlikely to damage a hard drive, industrial-grade electromagnets or very powerful neodymium rare earth magnets could potentially cause damage.
To protect your hard drives from magnets, you can store them away from magnets or devices that generate strong magnetic fields, such as speakers or motors. Even putting some distance between the magnet and the hard drive can significantly reduce the magnetic force. You can also use protective cases or bags made of materials that block magnetic fields, such as aluminium or copper.
It is recommended that you back up all data on your computer before travelling by air, just as a precaution.

Older X-ray machines used higher levels of radiation, so modern laptops are safer in modern X-ray machines
X-ray machines are a common feature of modern life, from the doctor's office to the airport security line. While X-rays are generally safe, they do emit radiation, a form of energy that can pass through most objects, including the human body. This property makes them useful for creating images of what's inside a person or a suitcase, but it also raises concerns about potential harm.
The potential harm caused by X-rays depends on the dose and the sensitivity of the exposed object or organism. In the case of living things, the risk of harm from X-ray radiation increases with the number of exposures and the dose. Children, for instance, are more sensitive to radiation and have a higher lifetime risk of developing cancer from it compared to adults. Similarly, women are at a higher lifetime risk than men for developing radiation-associated cancer after receiving the same exposures.
X-ray technology has evolved over time, and older machines used higher levels of radiation than their modern counterparts. This is because research has focused on ways to reduce radiation doses while improving image resolution and enhancing contrast materials and methods. Modern X-ray machines, therefore, use lower doses of radiation to generate images.
Modern laptops are safe from data loss or damage when passing through modern X-ray machines. Laptops and other electronic devices do not have any components that are photosensitive to light or X-rays. While theoretically, X-rays can affect flash storage by erasing some cells, the intensity of X-rays used in airport scanners is too low for this to occur. Additionally, solid-state drives, SD cards, and USB thumb drives use transistors, which are unaffected by X-rays.
