Airport security systems use X-ray technology to ensure the safety of travellers by identifying hidden weapons, chemicals, liquids, and other hazards that are not approved for airline travel. X-ray machines are used to screen carry-on items and checked luggage, with operators trained to look for suspicious items such as guns, knives, and components of improvised explosive devices (IEDs). These machines use non-ionizing radiation to scan travellers and their belongings, with the X-rays being surrounded by a metallic box to minimize leakage. While X-ray machines are generally safe for most items, they can damage unprocessed film, and travellers are advised to request hand-checks for film and photographic equipment. Additionally, travellers with certain medical conditions or concerns about radiation exposure may opt for a pat-down search instead of walking through X-ray machines.

This helps ease the screening process and ensures that prohibited items are not brought aboard the flight.
It is important to note that X-ray machines used at airports are designed to meet specific safety standards. The FDA's Center for Devices and Radiological Health (CDRH) ensures that all X-ray systems and other radiation-emitting screening equipment are built to use radiation safely. These machines are calibrated and maintained according to FDA requirements to limit passenger and worker exposure to radiation.
Additionally, X-ray machines used for carry-on items typically operate at lower levels of radiation compared to checked baggage scanners. This is because carry-on bags may contain items sensitive to radiation, such as film. Travellers are advised to request a hand-check for items that may be damaged by X-ray scanners, such as unprocessed film, to prevent any potential harm.
Overall, X-ray machines play a crucial role in ensuring the safety of air travel by allowing for the detection of prohibited and dangerous items while adhering to established safety standards for the protection of passengers and their belongings.

TSA officers use X-rays to locate prohibited items in passengers' belongings, such as weapons, chemicals, and liquids. They also screen personal electronic devices separately, including laptops, tablets, e-readers, and handheld game consoles.
TSA officers may instruct travelers to separate certain items from their carry-on bags, such as foods, powders, and materials that can clutter the bags and obstruct clear images on the X-ray machine. This helps to ease the screening process and ensure that prohibited items are not brought on board the aircraft.
TSA's X-ray equipment must meet FDA requirements to limit passenger and worker exposure to radiation. The FDA's Center for Devices and Radiological Health (CDRH) ensures that all X-ray systems are built to use radiation safely and are correctly calibrated and maintained.
Additionally, TSA incorporates unpredictable security measures and collaborates with intelligence and law enforcement agencies to adapt its security procedures based on evolving threats. For example, they may use advanced imaging technology (AIT) that uses non-ionizing radio-frequency energy and automated target recognition software to detect potential threats while protecting passengers' privacy.
TSA officers are trained to identify a wide range of prohibited items, from obvious weapons like knives and ninja throwing stars to more creative attempts, such as hiding vapes in toothpaste tubes or narcotics in hair scrunchies. They also screen service animal equipment, including collars, harnesses, leashes, backpacks, and vests, ensuring the safety of all passengers and crew.

X-ray systems can detect harmful contaminants in food
At airports, X-ray machines are used to scan carry-on items and checked luggage to identify hidden weapons and other hazards that are not approved for safe airline travel. These X-ray machines are designed to meet safety standards and limit radiation exposure for both passengers and workers.
X-ray technology is also widely used in the food industry for inspection and quality control purposes. X-ray systems can detect harmful contaminants in food products, ensuring product safety and integrity. This is particularly important as food producers are liable for contaminations that may harm consumers. X-ray inspection systems can identify a range of physical contaminants, including metal, glass, rubber, stone, and certain plastics. They can also detect product defects, such as missing items, broken products, or shape deviations.
The use of X-ray technology in food inspection offers several advantages. Firstly, it can penetrate food products without damaging them, allowing for the imaging of internal features. Secondly, X-rays can "see through" various types of packaging, including metallic packaging, to ensure the contents are contaminant-free. This makes it ideal for inspecting finished products with metallic packaging, such as juice pouches and snack bags.
However, X-ray inspection also has some limitations and disadvantages. It may not detect certain types of contaminants, such as thin foils, insects, hair, wood, fibres, and certain plastics. Additionally, X-ray inspection is relatively costly and requires high-voltage power supplies. There are also concerns about the potential exposure of operators to harmful levels of radiation, although the level of radiation received is typically lower than that from natural background radiation.
Overall, X-ray systems play a crucial role in detecting harmful contaminants in food, enhancing food safety, and meeting regulatory and consumer demands for product quality. By employing X-ray technology, food manufacturers can identify and mitigate potential hazards before products reach consumers.

X-ray machines are safe for food, drinks, and medications
X-ray machines used at airport security are safe for food, drinks, and medications. The machines use low-to-medium energy X-rays, which are not strong enough to cause any adverse effects on the items being scanned.
The X-ray screening process at airports is designed to identify dangerous items such as weapons, chemicals, and liquids that are not allowed as carry-on items. The machines use electromagnetic radiation to scan luggage and detect any prohibited items. This process does not affect the safety of the food, drinks, or medications inside.
In terms of food safety, X-ray machines do not induce radioactivity in items that were not previously radioactive. The radiation dose received by objects scanned by airport X-ray machines is typically 1 millirad or less, which is significantly lower than the average dose rate from background radiation (360 millirads per year). Additionally, food irradiation for preservation or pathogen destruction requires a minimum dose of 30,000 rad, far exceeding the levels used in airport X-ray machines.
Medications are also safe to pass through airport X-ray screening. If a drug's effectiveness or safety could be impacted by X-ray screening, this information would be indicated on the label or package insert. The FDA, which oversees labelling, is not aware of any drugs that require special instructions to avoid X-ray machines. However, if you have concerns about a specific medication, you can contact the manufacturer for more information or request a manual inspection of your medications at the airport.
Similarly, drinks and their containers are safe to pass through X-ray screening. While X-rays can interact with certain materials, the effect on water is minimal. Water is used as a cooling fluid in nuclear reactors, and while radiation can dissociate water molecules, it has a negligible effect on the nuclei of hydrogen and oxygen atoms. Any harmful byproducts, such as hydrogen peroxide, would require significant doses of radiation to form.

X-ray systems can damage unprocessed film
X-ray systems at airports are used to screen carry-on items and checked luggage for dangerous items such as weapons, chemicals, and liquids that are not allowed. The Transportation Security Administration (TSA) in the US uses X-ray machines for this purpose, and their equipment must meet FDA requirements to limit radiation exposure for passengers and workers.
Now, when it comes to unprocessed film, X-ray systems can indeed damage it. This is because certain X-ray machines, particularly the high-powered ones used for checked luggage, emit radiation that can fog and ruin unprocessed film. Specifically, CT (computed tomography) scanners, which are becoming more common in airports, have been known to damage film with just one pass. These scanners are much stronger than traditional X-ray machines and can even see through lead-lined bags, which were once used to protect film from radiation.
To avoid damage to unprocessed film, it is recommended to never put it in checked luggage. Instead, carry it in your hand luggage and request a hand inspection or manual check at the security checkpoint. Most TSA agents are accommodating of such requests, especially if the film is easily accessible and in a clear plastic bag or a "Do Not X-Ray" pouch. While film with an ISO rating of 800 or lower may be safe from damage by standard X-ray machines, it is always better to be cautious.
Additionally, when shipping film internationally, choose a commercial carrier like FedEx or UPS, as they do not typically use X-ray machines for packages. However, they cannot guarantee how other institutions, such as Customs, may handle your package. Including a “Do Not X-Ray” label or marking your package as “light-sensitive materials” can help reduce the risk of potential damage.
