Airport scanners are designed to ensure the safety and security of air travel. There are two main types: millimeter wave and X-ray scanners. While they operate on different principles, they both aim to identify potential hazards on persons or in luggage. X-ray scanners use penetrating radiation to create images of luggage contents, while millimeter wave scanners use harmless electromagnetic waves to produce thorough images of the body's surface, indicating hidden objects. Airport scanners can detect vaping devices and smoking activity, but their accuracy depends on variables such as object size, composition, placement, and concealment techniques. Disposable vapes, primarily made of plastic and aluminum, may appear as benign objects on scanner images due to their low density, but proper strategic packing is advised to minimize detection risks.

Airport scanners detect prohibited items, including vapes
Airport scanners are designed to ensure the safety and security of air travel. They aim to identify possible hazards hidden on persons or in luggage. There are two main types of scanners: millimeter wave and X-ray scanners. X-ray scanners use penetrating radiation to produce images of luggage contents, differentiating between innocuous objects and potential threats. Denser materials like metals and ceramics appear as opaque patches, while X-rays pass through organic items, resulting in lighter areas. Millimeter wave scanners, on the other hand, emit harmless electromagnetic waves that pass through clothing and reflect off hidden objects and the body, creating a detailed image of the body's surface.
These scanners can identify various materials, including metals, polymers, liquids, and ceramics. They are adept at detecting dense objects, but lightweight plastics or aluminum alloys may be overlooked. Disposable vapes, primarily made of plastic and aluminum, have a relatively low density and small size, making them easier to conceal in carry-on luggage or pockets. Their proximity to other objects and orientation within luggage can impact their detectability.
While airport scanners can detect prohibited items, including vapes, their detection accuracy depends on variables such as object size, composition, and placement. Some components are more easily flagged than others. Additionally, novel concealment techniques may challenge scanner operators, requiring adjustments and attention to detail.
It is important to note that while you can carry a vape on a plane, it must be placed in carry-on baggage, and you must follow safety measures to prevent the heating elements from activating during the flight. It is prohibited to use vape kits on the plane or in the airport, except in designated smoking areas.

X-ray scanners identify objects based on density
Airport scanners are designed to ensure the safety and security of air travel. There are two main types of scanners used: millimeter wave and X-ray scanners. X-ray scanners use penetrating radiation to produce images of the contents of luggage, differentiating between innocuous objects and potential hazards based on their density.
X-ray scanners work by projecting X-rays through objects, which are then detected on the other side, forming an image. Denser materials, such as metals and ceramics, absorb more X-rays and appear as opaque patches on the final image. Lighter areas indicate less dense materials, through which X-rays can pass more easily, such as organic items like food and clothing.
The radiological density of an object is determined by its density and atomic number (the number of protons in an atom's nucleus). For example, bones contain calcium, which has a higher atomic number than most other tissues, so they appear whiter on X-ray images. Conversely, less dense tissues like fat, muscle, and air-filled cavities appear as shades of grey.
Disposable vapes are primarily made of plastic and aluminum, which are relatively low-density materials. As a result, they may be missed by X-ray scanners, especially when strategically packed to minimize detection. However, there are other methods to detect vaping devices, such as smoke detectors, and scanners that detect devices emitting chemicals like propylene glycol, vegetable glycerin, and nicotine.
To comply with TSA guidelines, disposable vapes should be packed in carry-on baggage. Lithium-ion batteries in vapes must be properly packed to prevent safety risks, and liquids must adhere to specific volume restrictions.

Millimeter wave scanners identify objects on/in the body
Millimeter-wave scanners are whole-body imaging devices used to detect objects hidden beneath a person's clothing. They emit harmless electromagnetic waves that pass through clothing and reflect off the body and any concealed items. These scanners can detect metallic and non-metallic objects, including solids and liquids, by analysing the reflected waves and producing a detailed image of the body's surface.
The use of millimeter-wave scanners in airports has raised privacy concerns, as they can display intimate details of a person's body, such as prosthetics and medical equipment. In response, the TSA introduced Automated Target Recognition (ATR) software, which renders a generic body outline with highlighted suspicious areas. This software addresses privacy issues and complies with TSA requirements.
The accuracy of millimeter-wave scanners in detecting objects has been questioned in some studies. Factors such as object size, composition, and placement can impact their effectiveness. Additionally, there are concerns about the dissemination of scanner images, which may show individuals in a state of undress.
Regarding the detection of disposable vapes, airport scanners have limitations. Disposable vapes are typically made of plastic and aluminum, which have low density. This composition can make them less detectable by scanners, especially when strategically packed within luggage or pockets. However, vapes contain chemicals like propylene glycol and nicotine, which may be detected by the scanners designed to identify such emissions.
In summary, millimeter-wave scanners are used to identify objects on or inside the body by analysing reflected electromagnetic waves. While they have faced privacy and accuracy concerns, they remain a common technology for security screening at airports and other locations. The detection of disposable vapes depends on various factors, including the scanner type and the placement of the vape.

Disposable vapes are mostly plastic and aluminium—low-density materials
Airport scanners are designed to ensure the safety and security of air travel. They use either X-ray or millimetre wave technology to identify potential hazards in luggage or on individuals. X-ray scanners use penetrating radiation to create images of luggage contents, with denser materials such as metals and ceramics appearing as opaque patches. Millimeter wave scanners, on the other hand, use harmless electromagnetic waves that pass through clothing and reflect off the body and any concealed objects, creating a detailed image of the body's surface.
Disposable vapes, primarily made of plastic and aluminium, are constructed from low-density materials. This composition influences their detectability by airport scanners. While scanners excel at identifying dense materials, they may overlook lightweight plastics or aluminium alloys. As a result, disposable vapes may appear as benign objects on scanner images, resembling everyday items like electronic devices or toiletries.
The small size and compact design of disposable vapes further contribute to their potential concealment within carry-on luggage or pockets. However, several factors can impact their detection. The proximity of the vape to other objects, its orientation within the luggage, and the presence of metallic accents can all influence its detectability. Additionally, the type of scanner and the vigilance of security staff play a role in whether a disposable vape is detected.
To minimise the risk of detection, strategic packing is essential. Disposable vapes should not be placed in checked baggage, as they may be subject to more thorough screening. Instead, they should be packed in carry-on luggage, following guidelines for lithium-ion batteries and liquids to ensure safety and compliance with regulations.
While disposable vapes are permitted in luggage, vaping is prohibited in airports and on planes. It is important to adhere to airline restrictions and only use vaping devices in designated smoking areas, where permitted.
