Airport scanners and film
Airport scanners use waves to create an image of the body and detect objects that may be hidden under clothing. There are two types of body scanners: the millimeter wave scanner and the backscatter X-ray scanner. The former uses non-ionizing electromagnetic radiation in the radio band, while the latter uses very low-energy X-rays that are reflected back to the machine.
Film is sensitive to light and radiation, and X-ray machines can easily wipe undeveloped film. For this reason, photographers often request hand checks of their film. However, memory cards are much more immune to airport security scanners. Extensive tests by multiple organizations and manufacturers have confirmed that airport security scanners do not affect memory cards. The solid-state storage of a memory card is also more resistant than the magnetic media of laptop hard drives or smartphones.
While some sources claim that airport scanners cannot damage or alter the data on memory cards, others suggest that there is a risk of data loss or corruption, particularly for SD cards. To minimize this risk, it is recommended to keep SD cards in a protective case or a lead-lined bag, which can absorb X-ray radiation. However, lead-lined bags may not be allowed at all airports, and they may encourage security personnel to increase the intensity of the X-rays. Another option is to request a manual inspection of the SD card, although this may slow down the security line.
Overall, while airport scanners may pose a risk to film, memory cards are generally considered safe from corruption or erasure by airport scanners.

Memory cards vs. film
Memory cards and film are two different mediums for storing visual data. Film, the traditional medium, is more sensitive and prone to damage from airport scanners, whereas memory cards are more resilient and immune to airport security scanners.
Film is a photosensitive medium that reacts to light and radiation. In the past, photographers had to be cautious about airport X-ray scanners, as they could easily wipe undeveloped film. While manufacturers claim that film rated over 800 ISO won't be affected, many photographers still opt for hand checks or lead-lined film pouches to protect their film. However, these pouches can be heavy and may prompt security personnel to increase the X-ray volume, negating their benefit.
Memory cards, on the other hand, are much more durable and less susceptible to airport scanners. Extensive tests by multiple organizations and manufacturers confirm that airport security scanners do not harm memory cards. The solid-state storage of memory cards is significantly less sensitive than the magnetic media in laptop hard drives or smartphones. Even with numerous scans, there is little to no indication that airport scanners affect memory cards.
The differences in sensitivity between film and memory cards can be attributed to their underlying technologies. Film relies on light-sensitive chemicals to capture images, making it inherently vulnerable to light and radiation exposure. In contrast, memory cards use solid-state storage, which is less sensitive to external factors and provides greater durability.
While memory cards offer advantages in terms of scanner resilience, it's worth noting that both memory cards and film have their own considerations when it comes to storage and longevity. Film requires careful handling and development, while memory cards have their own set of best practices, such as avoiding deleting photo files individually to prevent corrupted data. Additionally, factors like speed and capacity play a crucial role in choosing the right memory card for specific tasks, especially when recording videos.
In conclusion, when comparing memory cards and film in the context of airport scanners, memory cards emerge as the more durable and convenient option. While film has its nostalgic and artistic appeal, memory cards offer greater peace of mind when passing through airport security, thanks to their resilience to X-ray radiation.

Memory card precautions
Memory cards are an essential part of digital photography, offering convenience and high storage capacities. While memory cards are generally resilient, it is important to take precautions to safeguard your valuable work. Here are some memory card precautions to consider:
Research and Choose Reliable Brands:
Look for reputable brands known for their reliability and durability. Some SD cards may offer additional protective features, such as shielding against X-ray radiation or reinforced construction to minimize the risk of damage.
Proper Handling and Storage:
Treat your memory cards with care. Always ensure your hands are clean when handling them, and hold them gently by the edges, avoiding the gold contacts. Store your memory cards in a protective case when not in use to shield them from dust, moisture, and physical damage. Keep them away from extreme temperatures and magnetic sources, as these can damage the data.
Backup and Clone Cards:
Before travelling, consider making backups or clones of your memory cards. That way, even if something happens to your original card, you have a safety net and can continue capturing moments uninterrupted.
Carry Multiple SD Cards:
Having backup cards provides peace of mind and guarantees uninterrupted photography. Carry at least two or three cards with you, especially if you require additional storage space or have specific cards dedicated to different purposes.
Data Recovery Services:
In the unfortunate event of data loss or corruption, remain calm and act strategically. Stop using the affected memory card immediately to avoid overwriting the lost data. Verify the issue by testing the card in different devices to rule out any compatibility problems. If needed, seek professional data recovery services, especially for critical or valuable data.
While airport scanners are not known to affect memory cards, taking these precautions will help ensure the safety and integrity of your data during your travels and photography endeavours.

X-ray intensity
The X-ray intensity of airport scanners is a concern for travellers carrying sensitive items such as memory cards and film rolls. While airport scanners use X-rays to screen carry-on items and checked luggage, the X-ray dose received is claimed to be minimal.
Backscatter X-ray machines, for example, use very low-energy X-rays that reflect off the skin and clothing of the person being scanned. The amount of radiation received from a backscatter machine is said to equal the amount of cosmic radiation received during two minutes of flight, indicating a very low health risk.
Cabinet X-ray systems, used for screening checked luggage, also have protective features. These machines are enclosed in thick cabinets with lead curtains at entry and exit points to ensure the safe passage of luggage through the X-ray beam.
Despite these assurances, some travellers remain concerned about the potential impact of airport scanners on their electronic devices. It is recommended that travellers take precautionary measures to protect their memory cards and other data storage devices when passing through airport security. Using a lead-lined bag or pouch can provide some protection against X-ray radiation. However, it is important to check airport regulations, as some may not allow such bags or pouches.
Additionally, storing memory cards in carry-on luggage is generally recommended, as this luggage is typically subjected to less intense X-ray scanning compared to checked baggage. While formatting an SD card before travelling may erase the file system, it does not provide any added protection against X-ray radiation. Travellers are advised to research and choose reputable brands of memory cards, as some may offer additional protective features, such as shielding against X-ray radiation.

Memory card resilience
Memory cards are remarkably resilient to damage from airport scanners. Extensive tests by multiple organisations and manufacturers have shown that airport security scanners do not affect memory cards. Memory cards are immune to airport security scanners because they are 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.
However, it is important to note that not all airports use the same type of scanners, and some scanners may potentially damage memory cards. It is always advisable to take precautions to protect your memory cards. Some memory cards may have additional protective features, such as shielding against X-ray radiation or reinforced construction. Using a lead-lined bag or pouch can also provide some protection against X-ray radiation for your memory card. The lead lining helps to absorb the radiation, reducing the potential damage to the data on the card. Alternatively, you can carry your memory cards in your pocket and pass through the personnel scanner instead of the conveyor belt scanner.
If your memory card does get damaged by an airport scanner, do not attempt to format or retrieve data from it, as this could worsen the situation. Instead, contact the airport authorities and seek professional data recovery services if the data is critical or valuable. To minimise the risk of data loss, it is recommended to back up your memory card frequently.
