Airport baggage scanners are security devices that use advanced X-ray technology to detect dangerous, prohibited items and substances in luggage, such as metallic and non-metallic objects, organic materials, and indications of drugs. They provide detailed images that help security officers identify items based on their density and atomic number. While scanners may not directly identify drugs, they assist security forces in detecting suspicious luggage by providing visual clues. These devices are crucial for ensuring aviation safety and preventing illegal activities.

What You'll Learn
Airport scanners can detect metallic objects
Airport scanners are designed to meticulously inspect the contents of travellers' luggage to ensure aviation safety. They can detect metallic objects, such as knives, guns, and other weapons, by utilising X-ray technology. The X-rays interact with metal, creating distinct images on the security monitor that highlight metallic items. This technology can detect even the smallest amounts of metal, making it highly effective in identifying potential threats.
Metal detection remains a critical aspect of airport security, as most weapons, including firearms, knives, and bomb components, are metallic. The distinct appearance of metal on X-ray images allows security personnel to easily identify these items. Even small parts of firearms, like screws or springs, can be detected due to their metallic properties. Additionally, the presence of metal in luggage can raise suspicion and prompt further inspection for potential explosive devices, which often have metallic components.
Millimetre-wave scanners, metal detectors, and backscatter X-ray machines are commonly used in airport security. These machines use non-ionizing radiation to detect hidden metallic objects. When luggage is scanned, X-rays pass through and interact with its contents. The X-rays that pass through are then detected and converted into signals, creating images that highlight the objects inside. This technology allows security officers to identify items based on their density and atomic number, distinguishing between metals and other substances.
While airport scanners are highly effective at detecting metal, they also have the capability to identify non-metallic and organic materials. They can distinguish between various substances and detect indications of organic materials such as food, liquids, drugs, and explosives. Advanced imaging technology and explosive detection systems further enhance the ability of airport scanners to identify potential threats, ensuring the safety of air travel.

They can also detect non-metallic objects
Airport baggage scanners are designed to ensure the safety of air travel by meticulously inspecting the contents of travellers' luggage. They can detect non-metallic objects such as plastic explosives or contraband that could pose a threat to aircraft security. Objects made from non-metallic substances such as plastics, ceramics, and glass are identified through their density and atomic number, which affect how much they absorb or scatter X-rays.
While airport scanners cannot directly detect drugs hidden in luggage, they can assist security forces in detecting suspicious items. For example, scanners can detect pills, whether in plastic, non-metallic, or metallic bottles. They can also identify pills in liquid form.
Airport scanners can also detect organic materials. While they may not always be able to establish what the organic substance is, security personnel will manually inspect the luggage to determine if it is drugs.
Overall, airport scanners can identify anything that isn't part of the human body, including items concealed under clothing or layers. They can detect even the smallest amounts of metal and paper, and they look for anomalies, so if currency is arranged in bundles, for example, it will be more easily detected.

Organic materials can be identified
Airport baggage scanners are designed to ensure the safety of air travel by meticulously inspecting the contents of travellers' luggage. They can detect metallic and non-metallic objects, but they can also identify organic materials.
Although scanners cannot directly detect drugs, they can assist security forces in detecting suspicious luggage. Security staff can spot objects with unusual shapes, such as guns, knives, or explosives, and then manually inspect the luggage to ensure it does not contain prohibited items.
Additionally, scanners can detect pills, whether in plastic, non-metallic, or metallic bottles, and even in liquid form. They can also identify paper and money, especially if it is bundled or arranged in an unusual manner.
Overall, airport scanners can identify organic materials and play a crucial role in aviation safety by detecting prohibited items and substances.

Scanners can detect pills and liquids
Airport scanners use X-ray technology to see through luggage and meticulously inspect its contents. They can detect metallic and non-metallic objects, including weapons such as guns and knives, by differentiating between various substances based on their density and atomic number.
While airport scanners cannot directly identify drugs, they can detect pills and liquids by providing visual clues about their presence. For example, if pills are contained in plastic, non-metallic, or metallic bottles, they will be visible to the scanners. Additionally, scanners can detect the smallest amounts of metal, so they will capture images of pills even if they are contained in foil packaging.
Scanners can also detect indications of substances like drugs and explosives. They can identify organic materials, and substances like food or explosives appear orange on the monitor. While explosives drug detection systems can quickly analyse liquid containers and their contents, they do not directly detect drugs. Instead, they provide visual hints that may indicate the presence of drugs.
Full-body X-ray machines can detect if a person's stomach contains packages, even if the pills are in liquid form. However, if travelling with pills in liquid form in carry-on baggage, the liquid must not exceed 3.4 ounces or 100ml.

They can also detect money
Airport scanners are primarily designed to detect items that may pose a threat to aviation security, such as weapons, explosives, and contraband. However, they can also detect money. While not designed specifically to identify currency, airport scanners utilise advanced imaging technologies, including X-ray, gamma ray, and neutron scanning, to inspect luggage contents. These scanners create images based on the density and material composition of the items inside luggage.
Currency notes, especially in large amounts, have a distinctive appearance on these X-ray images. They often appear as stacks of uniform rectangular shapes that can be easily distinguished from other items. Additionally, modern currency often incorporates security features that interact with light, such as thin-film interference effects or diffraction gratings found in polymer bills, which can further reveal their presence during scanning.
Advanced Imaging Technology (AIT) scanners, which create detailed images of a passenger's body to detect concealed items, may also indicate the presence of money. While not designed for currency detection, these scanners can reveal unusual bulges or shapes that could prompt further inspection, potentially leading to the discovery of large sums of money.
It is important to note that the primary goal of airport security scanners is to ensure the safety and security of air passengers and uphold the security of air travel. Detecting large sums of cash can also be crucial in preventing money laundering and other financial crimes. Customs regulations regarding currency limits should be considered by passengers to avoid penalties during inspections.
