What You'll Learn
Airport scanners can detect metallic and non-metallic objects
Airport scanners have evolved to meet the unique demands of airport security. The primary purpose of airport scanners is to detect anything that may endanger lives, such as weapons, explosives, or other threats.
Metal Detection
Metal detection remains a priority, and most airport scanners can detect even the smallest amounts of metal. Metal detectors use magnetic fields to identify metal objects. The magnetic field is reflected back to the machine if metal objects are present, and a beeping noise alerts the security agent. Metal detectors can identify metallic objects such as firearms, knives, and bomb components.
Non-Metal Detection
However, with the increasing use of non-metallic materials in creating weapons and other threats, airport scanners have also advanced to detect non-metallic objects. Millimeter-wave scanners, for example, can detect both metallic and non-metallic items, including weapons, explosives, and drugs hidden under clothing or in body cavities. Advanced X-ray scanners can also identify non-metallic objects by analyzing their shape, density, and other visual cues. These scanners are effective in detecting plastic or ceramic weapons and explosive components, which are challenging for older security systems to detect.
Advanced Imaging Technology
Airport scanners also employ advanced imaging technology, such as attenuation imaging scanners (ATI), which provide X-ray images to security officers. While the scanners themselves do not detect drugs, the images they produce allow trained officers to identify potential threats, including drugs. This triggers a more comprehensive security process to ensure the safety of passengers.
Other Detection Methods
In addition to scanners, other methods are used to detect drugs and explosives, such as chemical-based scanners, bomb-sniffing dogs, and passenger profiling. These methods complement the use of scanners to enhance overall airport security.

Scanners can detect organic materials, which include drugs
Airport scanners are designed to detect metallic and non-metallic objects, including organic materials such as drugs, food, explosives, and paper. While the scanners cannot identify the exact composition of these materials, they can distinguish between organic and inorganic substances and determine their density. Objects that appear suspicious on the scan are further inspected by security personnel, who employ various methods, such as swab tests, sniffer dogs, and full-body X-ray scans, to identify contraband items, including drugs.
The most common type of airport scanner is the Advanced Imaging Technology (AIT) scanner, also known as an attenuation imaging scanner or a millimeter wave scanner. These scanners use millimetre waves to create an image of the passenger's body and any concealed items. While AIT scanners prioritize passenger privacy by displaying only a generic outline, they are effective at detecting both metallic and non-metallic objects, including drugs.
In addition to AIT scanners, airports also employ metal detectors, facial scanners, and trace portal machines. Metal detectors are useful for detecting metallic weapons, while trace portal machines are specialized for detecting non-metallic items, such as explosives and drugs. These machines work in conjunction with the expertise of security officers, who interpret the scans and make decisions about further security procedures.
It is important to note that body scanners do not have the capability to see inside body cavities. Therefore, drugs or hazardous liquids hidden inside a person's body would not typically be detected by the scanners alone. However, if such items are concealed in pockets or baggage, they may be identified through the scanning process and subsequent inspections.
To avoid any issues during security screening, it is recommended to follow airline guidelines and declare any medications or supplements in their original packaging. Additionally, passengers should be prepared for the possibility of additional screening procedures, such as pat-downs or further inspections of their belongings.

Scanners can detect threats, but not identify them
Airport scanners are designed to detect threats, such as weapons or explosives, to ensure the safety of passengers and staff. While they can detect metallic and non-metallic objects, they cannot always identify the specific objects in luggage or on a person. For example, they can detect the density and mass of items and differentiate between organic and inorganic materials, but they do not identify the exact composition.
The most common type of airport scanner is the Advanced Imaging Technology (AIT) scanner, also known as the attenuation imaging scanner or ATI scanner. These scanners use millimetre-wave technology to detect potential threats in a matter of seconds. They work by sending waves through clothing that reflect off the passenger's skin and any concealed items, creating an image that is then interpreted by the machine. While these scanners can detect objects in pockets, they do not see beneath the skin and will not detect items hidden inside body cavities.
Although airport scanners can detect some threats, they rely on the skills of security officers to identify potential dangers. TSA officers interpret the X-ray images produced by the scanners to decide if a passenger poses a threat and requires further screening. In addition to scanners, security officers use other methods to detect drugs and illegal objects, such as metal detectors, pat-downs, and swab tests.
It is important to note that airport security measures are unpredictable, and all travellers will be screened. By following the rules and regulations, passengers can help ensure a smooth security process and avoid any issues during their travel.

Scanners can detect the density and mass of objects
Airport scanners are sophisticated machines that can detect the density and mass of objects. They use various types of energy, such as X-rays and millimeter waves, to scan objects and individuals. The primary goal of these scanners is to identify dangerous or prohibited items, preventing these materials from entering secure areas or being transported by air.
X-ray scanners are commonly used for luggage and carry-on items. They produce images that show the density and composition of materials inside bags, helping security personnel distinguish between harmless items and potential threats. For example, certain drugs may resemble harmless organic items, but X-ray scanners can flag them for further inspection by detecting their density and structure. Additionally, X-ray scanners can detect the smallest amounts of metal, paper, and even money.
Millimeter-wave scanners are often used for scanning people. These scanners emit low-energy waves that penetrate clothing, allowing the detection of hidden objects without physical contact. They can identify objects concealed on a person's body and are crucial for detecting threats like guns and knives. If no threats are detected, the screen turns green and displays an "OK" message.
While airport scanners can detect the density and mass of objects, they may not always identify the specific substance. For example, organic materials like drugs, food, explosives, or paper may appear in an orange color, indicating a need for further inspection. Advanced imaging technology provides visual clues that trained security officers use to decide if a passenger poses a threat and requires additional screening.

Scanners do not detect drugs, but security officers can
While airport scanners can detect a wide range of metallic and non-metallic objects, they do not specifically identify drugs. These scanners use advanced imaging technology to create X-ray images or outlines, which help security officers identify potential threats. The scanners can detect the density and mass of objects, differentiating between organic and inorganic materials. Organic materials, such as drugs, food, explosives, or paper, are marked with an orange colour. However, the scanners rely on the interpretation of security officers to determine if an object is suspicious.
Although scanners cannot directly detect drugs, they can provide visual clues about the presence of drugs. For example, if drugs are hidden under clothing or in baggage, the scanner may indicate unusual shapes or densities that arouse suspicion. In such cases, security officers may conduct a further search of the individual's belongings or perform a pat-down to ensure safety.
Additionally, passengers suspected of swallowing drugs may be subjected to a full-body X-ray scan, which can detect packages in the stomach. However, this is not a standard procedure and requires specific suspicion.
To enhance drug detection, airports employ multiple methods beyond scanners. These include metal detectors, pat-downs, swab tests, sniffer dogs, and trace portal machines. These additional measures help identify potential drug possession or other security risks.
It is important to note that the primary goal of airport security is to ensure the safety of passengers and staff. While scanners play a crucial role in threat detection, the interpretation of the scanned images by trained security officers is essential to identifying potential risks, including the presence of drugs.
