What You'll Learn

Insulin pens are allowed through airport scanners
Insulin pens and diabetes-related supplies, equipment, and medications are allowed through airport scanners and detectors. However, it is important to notify the TSA officer that you have diabetes and are carrying these supplies. While insulin pens can be taken through airport security, it is recommended to keep the necessary documents handy in case you are asked about them. Additionally, insulin vials and cartridges can be X-rayed along with the rest of your hand luggage.
Most insulin pumps and CGMs should not be screened by X-ray or security scanners on the luggage belt. Instead, carry them with you for manual inspection. Many UK airports now offer hidden disability Sunflower lanyards for those with hidden disabilities, such as type 1 diabetes, to indicate that they may need extra help or understanding from security staff. You can obtain one of these lanyards at the airport's Special Assistance desk or by contacting Special Assistance before your travel.
It is also recommended to contact the airport before your journey to learn about the scanners they have in place and if there are alternative ways to pass through security. Additionally, consider carrying your insulin and related supplies in a separate bag within your carry-on luggage to make the security process quicker and easier. You can also use a clear plastic bag to enhance convenience.
While airport body scanners use Advanced Imaging Technology (AIT) and millimeter wave technology to detect metallic and non-metallic objects, they do not show images of passengers' naked bodies or detect items inside their bodies.

Metal vape pens may be detected by scanners
Metal vape pens may be detected by airport scanners, but this is not a certainty. Airport scanners are designed to detect metal objects, so if a vape pen has metal components, it will likely be picked up by the scanner. However, not all vape pens contain metal, and even those that do may go undetected if they are small enough.
Vapes are typically made of metal or contain metal components, so they can often be easily detected by scanners' metal detectors. The materials used in vapes, such as the metal casing and lithium-ion batteries, are particularly visible under X-rays. This means that security agents can clearly see these devices and may flag them for closer inspection if necessary.
It is important to note that airport scanners are not specifically designed to detect vape pens. They are looking for potential security threats, so if a vape pen does not raise any concerns, it may go unnoticed. Additionally, the variety of materials used in vape pens, including plastic, metal, and glass, can sometimes make it difficult for scanners to detect them. The size and shape of vape pens can also vary greatly, further impacting their detectability.
To avoid complications when travelling with a vape pen, it is crucial to adhere to airport and TSA guidelines. Vape pens and electronic vaping devices must be kept in carry-on bags and are not permitted in checked luggage. It is also important to prevent accidental activation of the heating element during transportation and to follow liquid restrictions for e-juices.

Airport scanners can detect indications of drugs
Airport scanners are designed to detect metallic and non-metallic objects, including weapons, explosives, and other illegal objects. While they cannot specifically identify drugs, they can detect visual clues that indicate the presence of drugs. For example, they can distinguish between organic and inorganic materials, with organic materials such as drugs, food, explosives, or paper appearing in orange colour. Additionally, passengers suspected of swallowing drugs may be scanned with a full-body X-ray machine, which can detect packages in the stomach.
The most common type of airport scanner is the Advanced Imaging Technology (AIT) scanner, also known as the attenuation imaging scanner. These scanners use millimetre wave technology to detect a wide range of metallic and non-metallic objects. They work by sending millimetre waves through clothing and reflecting them off the passenger's skin and any concealed items. The waves then bounce back an image, which is interpreted by the machine. AIT scanners prioritize privacy and only display a generic outline without revealing gender or body type.
While airport scanners are not designed to specifically detect vape pens or other electronic smoking devices, they can detect metal components in these devices. If a vape pen has metal parts, it is likely to be picked up by the scanner. However, plastic vape pens may go undetected, especially if they are small. It is important to note that while these devices are allowed in carry-on baggage, they are prohibited in checked bags.
To ensure the safety of passengers and staff, airport security officers play a crucial role in interpreting the images produced by scanners and making informed decisions. Their trained eyes can identify potential threats, including drugs, and initiate further security measures if necessary. Therefore, while airport scanners themselves do not detect drugs, they provide valuable visual information that assists security officers in their assessments.
In conclusion, airport scanners play a vital role in enhancing aviation security by detecting various objects, including potential indicators of drug possession. While they may not directly identify drugs, they provide visual clues that aid trained security officers in their decision-making process. This combination of advanced technology and skilled human analysis helps maintain a safe travel environment for all stakeholders.

Scanners use X-ray technology to see through luggage
Airport scanners use X-ray technology to see through luggage and ensure the safety of passengers and staff. The X-rays pass through the luggage, with some getting absorbed and others passing through and reflecting off the contents. This creates a detailed image on the scanner screen, showing the dense and light areas inside the bag. Security officers can then study these images to identify items based on their density and atomic number. For example, metallic objects like knives and guns will show up clearly and distinctly on the security monitor.
Non-metallic objects, such as those made from plastics, ceramics, or glass, can also be identified through their interaction with X-rays. These materials absorb and scatter X-rays differently, allowing security officers to distinguish between various substances. This technology is not just used to detect weapons or explosives but also to identify other potential threats or prohibited items, such as illegal drugs or stolen property. It is also used to ensure that passengers are not transporting dangerous items that could pose a risk during the flight.
While X-ray technology is commonly used for luggage scanning, some airport scanners use other technologies, such as millimeter wave scanners or backscatter X-ray machines. These scanners use very low-energy X-rays or non-ionizing radiation to detect potential threats without exposing passengers and staff to high levels of radiation. The amount of radiation from these scanners is equivalent to the amount of cosmic radiation received during two minutes of flight, and it is considered very low risk.
In terms of insulin pens, insulin vials, and cartridges, these are allowed through airport security scanners and can be X-rayed with the rest of your hand luggage. However, insulin pumps and continuous glucose monitors (CGMs) should not be screened by X-ray or security scanners on the luggage belt and should be carried separately for manual checking. It is always a good idea to contact the airport before your journey to understand their specific procedures and requirements.
