Airport security scanners pose a threat to certain items, but do they damage cassette tapes? X-rays are not inherently magnetic, and while there is some magnetic energy as a byproduct, it is not enough to damage cassette tapes. There is also no danger to digitally formatted media, like cassette tapes, if you carry them onto the plane. However, it is recommended to keep them in your carry-on luggage, as there have been reports of tapes getting erased while in checked baggage. If you are concerned, you can request a hand check of your cassette tapes at the airport.

What You'll Learn
X-ray machines are not strong enough to damage cassette tapes
X-ray machines used in airport security are not strong enough to damage cassette tapes. While X-rays do produce some magnetic energy as a byproduct, it is not sufficient to damage cassettes or VHS tapes. X-rays are simply high-frequency light and do not affect magnetic media.
X-ray machines are not inherently magnetic, and the magnetic energy they produce as a byproduct is minimal. Therefore, the X-rays themselves will not damage your cassette tapes. However, it is important to keep your tapes out of checked baggage and carry them in your hand luggage instead. The large transformer powering the X-ray equipment may generate a strong magnetic field that could potentially harm your tapes.
Additionally, it is recommended to keep your tapes away from extreme temperature changes and humidity, as these conditions can be harmful. If you are travelling to a tropical location, it is advisable to seal your cassettes in bags to protect them from moisture.
If you are concerned about potential damage, you can request a hand check for your bag containing the tapes. Most TSA agents are accommodating of such requests, especially if you keep your tapes easily accessible in a clear bag.
Overall, while X-ray machines themselves are not strong enough to damage cassette tapes, it is advisable to take precautions to ensure the safety of your tapes during airport screening.

Magnetic fields from X-ray transformers can damage tapes
While X-rays are not inherently magnetic, there is some magnetic energy created as a byproduct. However, this is not usually enough to damage VHS tapes or cassettes. For example, one source notes that they have travelled the world with audio- and videocassettes and have gladly reported no damage.
However, some sources suggest that the magnetic field from the large transformer powering the X-ray equipment can damage tapes. This is because tapes are sensitive to magnetic fields. Therefore, it may be best to keep tapes in carry-on luggage and request a hand check.

CT scanners can damage film
CT scanners are becoming increasingly common in U.S. airports and, unlike traditional X-ray machines, they are significantly more powerful. Unfortunately, this added strength can mean serious damage to unprocessed film. The United States Transportation Security Administration (TSA) has rolled out the use of CT scanners as the latest "threat detection" equipment for airport security. These scanners are similar to those used in the medical field and create a 3-D image that can be viewed and rotated 360 degrees for a thorough analysis.
Film photographers are concerned about the impact of CT scanners on their film when passing through airport security. Indeed, CT scanners can cause irreversible damage to film, including “fogging", distortion in shadow detail, and general image degradation. One pass through a CT scanner can damage a roll of film, making it important for photographers to take precautions when travelling with film.
To avoid damage to film when passing through airport security, it is recommended to request a hand-check by a TSA agent. Most U.S. agents are accommodating of such requests, especially when the film is easily accessible and out of its packaging. Placing film in a clear ziplock bag or a "Do Not X-Ray" film pouch is also suggested. It is important to never put film in checked baggage, as the scanners used for these bags are more powerful and damaging.
Additionally, it is recommended to remove film from all canisters and packaging ahead of time and to keep it in a side pocket of carry-on luggage. Mailing exposed rolls directly to a photo lab before flying home is another option to consider. While lead-lined film bags can block standard X-rays, they are ineffective against CT scanners and may result in more damage to the film. Overall, requesting a hand-check remains the safest and most effective way to protect film when travelling through airports with CT scanners.

Humidity and temperature changes can damage cassettes
While X-rays and airport security scanners are unlikely to damage cassettes, humidity and temperature changes can. Tapes should be stored in a location that maintains a humidity between 40% and 60%. If the humidity is too low, the tape can become brittle and break. If it is too high, the tape can get mouldy and become unwatchable.
Cassette tapes are wound under a considerable amount of tension to maintain their shape. A reel of tape can be permanently damaged if the tape pack tension is too high or too low. If the tension is too high, the tape backing can stretch. If the tension is too low, tape layers can slip past each other, resulting in pack slip, cinching, or popped strands on playback. Relaxation, stretching, and deformation of the tape backing can cause mistracking of a videotape or sound distortion on an audio tape. Every time a tape pack is heated or cooled, the tape pack tension will increase or decrease, respectively. Therefore, storing tapes in an environment with consistent temperature and humidity is ideal.
If you are travelling with cassettes, it might be a good idea to bag electronic items and not use any cassettes until any condensation has dried out. If you are travelling to a hot and humid location, it is recommended to keep your cassettes in your carry-on luggage.
To avoid damage from temperature and humidity, it is recommended to store tapes in a sealed container in a cool, dry place. The ideal temperature for storing cassettes is between 60 and 80 degrees Fahrenheit.

Metal detectors are safe for cassettes
It is worth noting that while X-rays themselves do not pose a threat to cassettes, the magnetic field from the large transformer powering the X-ray equipment could potentially cause damage. However, this risk is minimal, and cassettes can be safely carried through metal detectors without concern.
To ensure the safety of cassettes during airport screening, it is recommended to keep them in carry-on baggage rather than checked baggage. Additionally, older formats of tapes should be prioritized in carry-on bags as they have a lower threshold for magnetic damage than newer formats. Following these guidelines will help ensure that cassettes are not affected by airport security procedures.
In summary, metal detectors in airport security are safe for cassettes. The magnetic fields generated by these metal detectors are not strong enough to cause any damage to cassettes or other magnetic media. By taking some simple precautions, such as keeping cassettes in carry-on baggage, travelers can ensure the safe passage of their media through airport security.
