What You'll Learn
Airport scanners can detect metallic and non-metallic objects
Airport scanners are designed to detect a wide variety of materials, from metallic to non-metallic objects, as well as organic compounds. They play a pivotal role in ensuring aviation safety by meticulously inspecting the contents of travellers' luggage and bodies.
Metallic Objects
Metal objects are easily detected by airport scanners due to the interaction of X-rays with metal. This creates a distinct image on the security monitor, allowing for the identification of items based on their density and atomic number. Metals appear as dark orange or blue on the screen. Even small amounts of metal can be detected, and metal detectors will alert TSA agents with a beeping noise.
Non-Metallic Objects
Non-metallic objects, such as those made from plastics, ceramics, and glass, are identified through their density and atomic number, which affect how much they absorb or scatter X-rays. This makes it possible to detect items that may pose a security threat, such as plastic explosives or contraband.
Organic Materials
Airport scanners possess advanced technology that enables them to sensitively identify organic materials such as drugs, food, explosives, paper, and liquids. These materials are typically marked with an orange colour on the scanner image. While scanners may not directly detect drugs, they can provide visual clues about the presence of organic substances, prompting further investigation by security personnel.

They can identify organic materials like food, drugs, and explosives
Airport scanners use X-rays to penetrate luggage and collect detailed images of the items inside. They can detect metal, non-metal, and organic materials. Organic materials include drugs, food, explosives, and paper. While scanners cannot directly detect drugs, they can detect an organic mass with a high density, which security personnel will then inspect further to determine whether the item is a drug. The density of commonly used drugs is well-known to airport security officials.
Explosive Detection Systems (EDS) are designed to identify the molecular makeup of various explosives. EDS scanners work by analyzing how organic compounds absorb X-rays, which helps detect even trace amounts of explosives in luggage or on a person's body.
Powdered substances can also be analyzed by airport scanners, ensuring that drugs or bomb-making materials do not pass through security unnoticed. Scanners can also detect the chemical composition and the containers substances are stored in, which helps identify potential risks.
Airport scanners can also detect items wrapped in materials designed to evade detection. They can also see through the human body and detect items concealed under clothing.

Scanners cannot see inside the human body
Airport body scanners have evolved over the years, and today's machines in the US, Canada, and the European Union rely on electromagnetic millimeter waves. These waves are sent toward a passenger's insides, passing through clothing and reflecting off the skin and other objects to create an image that is interpreted by the machine. Importantly, these scanners do not reveal what is inside a person's body or buried under the skin. Instead, they detect the contour of the body and can identify concealed metallic and non-metallic items on the body or in clothing. This technology is considered safe for pregnant people and those with pacemakers, surgical metal implants, or breast implants.
While millimeter-wave scanners do not show the inside of the body, X-ray scanners, including full-body X-ray machines, can detect items inside body cavities or swallowed objects, such as pills or drugs. These X-ray scanners are typically used for luggage and are effective at identifying metallic and non-metallic objects, organic materials, and the density and mass of items. However, they do not always identify the specific objects and may require further inspection by security personnel.
In summary, while airport scanners can detect items on or inside clothing, they do not have the capability to see everything inside the human body. The millimeter-wave technology used in many countries ensures privacy while maintaining security, as passengers can see a generic human shape on the screen rather than their detailed body image.

They can detect items concealed under clothing
Airport scanners use X-rays to penetrate the luggage surface and collect detailed images of the items inside. They can detect metallic and non-metallic objects, as well as organic materials. This is done by calculating the mass and density of the contents. While they may not always be able to establish what the objects are, they can detect anomalies and items that arouse suspicion.
Full-body scanners use Advanced Imaging Technology (AIT) and millimeter-wave technology to detect items on a person's body. They emit non-iodizing waves and use backscatter technology to see detailed images under clothing. These waves interact with the skin and any concealed items, reflecting back an image that the machine can interpret. This technology can detect metallic and non-metallic items, such as weapons and explosives, that may be hidden under clothing.
Millimeter-wave scanners generate a 3D image of the passenger and are highly effective at detecting concealed objects. Backscatter X-ray scanners, on the other hand, produce a 2D image using low-level X-rays. These scanners are also used to find items that may be hidden on an individual.
While body scanners cannot see inside the body, they can detect items concealed under clothing. This includes pills, which can be spotted even if they are inside plastic, non-metallic, or metallic bottles. Airport scanners can also detect the smallest amounts of metal, paper, and organic materials such as food and drugs.
Overall, airport scanners are highly effective at detecting items concealed under clothing, ensuring the safety of passengers and preventing the transportation of dangerous or prohibited items.

Scanners use X-rays to see through luggage and create images
Airport scanners use X-rays to see through luggage and create images. The scanners release X-rays that pass through the bag, calculating the mass and density of the contents. Different materials absorb X-rays in different amounts, with metals appearing as dark orange or blue on the screen, and organic materials like food, paper, or drugs appearing as shades of green or lighter colours. Security officers can then study these images to accurately identify items inside the luggage.
X-ray scanners use low levels of ionizing radiation to create an image of the contents of a passenger's luggage. They can detect metal, non-metal, and organic materials. This helps prevent the smuggling or sale of prohibited food and items. They can also detect the mass and density of everything packed in luggage, although they are not always able to establish what the objects are. If the contents arouse suspicion, security will manually inspect the bag.
Millimetre wave scanners are another type of scanner used in airports. They use non-ionizing radiofrequency waves to detect threats. These machines bounce the waves off the body and back to the machine. They emit far less energy than a cell phone and are safe for passengers. They can detect a wide range of items, including weapons, explosives, liquids, sharp objects, and pills.
Full-body scanners are placed at customs checkpoints and use millimetre waves and backscatter technology to see detailed images under clothing. They can detect metallic and non-metallic items, such as weapons, explosives, and drugs.
