Airport scanners are designed to detect metallic and non-metallic objects, including organic materials such as food, paper, and drugs. The scanners produce images in orange, blue, and green, with orange indicating organic material, blue indicating metal, and green indicating non-organic materials like plastic. While they can identify organic materials, they cannot determine the exact composition of an object. For example, scanners can detect an organic mass with a large density, but security personnel will need to investigate further to determine if it is an illegal substance. Additionally, high-density materials like gold can be detected, but they cannot be differentiated from other similarly dense objects. Overall, airport scanners play a crucial role in enhancing security by providing visual cues about the materials carried by passengers.
| Characteristics | Values |
|---|---|
| Can airport scanners detect organic materials? | Yes, airport scanners can detect organic materials. |
| How do they do this? | Airport scanners use X-rays to see through luggage and build detailed images of the items inside. |
| What are the images like? | Current airport X-ray scanners produce images in orange, blue and green. Each colour corresponds to a material category—orange means organic material, green is for medium-dense non-organic materials, and blue means metals or hard plastics. |
| Can they detect exact materials? | No, they cannot determine the exact composition of an object, but they can tell if an object is organic or metallic (or low density or high density). |
| Can they detect drugs? | Airport scanners can detect an organic mass with a large density, which airport security personnel will then investigate to determine whether the detected item is a drug or not. |
| Can they detect items inside the body? | No, X-ray machines cannot detect items inside the body if they are made of the same general chemical composition as the rest of the body. |

Airport scanners can detect both metallic and non-metallic objects
Airport scanners are designed to detect a wide variety of materials, including both metallic and non-metallic objects. While metal detection remains a priority, non-metallic materials are increasingly being used to create weapons and other threats. Airport scanners use different kinds of technology to detect objects.
Backscatter X-ray scanners, for example, can detect both metallic and non-metallic objects, ranging from guns to food, plastics, and drugs. They can also detect organic materials such as explosives. Millimeter-wave scanners, on the other hand, use non-ionizing radiofrequency waves to detect hidden threats such as guns and knives. They are also capable of detecting both metallic and non-metallic objects.
Advanced imaging technology is also used to detect metallic and non-metallic objects. Matrixcope scanners, for instance, can identify a wide range of organic and chemical compounds, in addition to metallic and non-metallic objects. They also have explosive detection systems and rapid processing times, ensuring high security without compromising efficiency.
Airport scanners can also identify the density of objects, which helps determine if an object is organic or metallic. While they cannot determine the exact composition of an object, they can provide visual cues about the material, such as different colours. This helps security personnel identify suspicious items and conduct further investigations if needed.

They can identify organic material, including food, paper, and drugs
Airport scanners can detect organic materials, including food, paper, and drugs. While older scanners cannot determine an object's exact composition, they can tell if an object is organic, metallic, or low or high density. This means that while they can detect gold, for example, they cannot differentiate it from other high-density materials like tungsten or platinum.
Modern airport scanners, on the other hand, have extremely sophisticated technology and can see everything in your luggage, including any concealed items. These scanners use X-rays to see through luggage and build detailed images of the items inside. They can detect metallic and non-metallic objects, including guns, food, plastics, and drugs.
Backscatter X-ray scanners, for instance, create a moving image of the body and can detect objects hidden beneath clothing or in luggage. Millimeter-wave scanners produce a single image and emit less energy, making them safer. Both types of scanners can achieve a detailed view of the body beneath the clothes, including hair extensions, bobby pins, and underwire bras, which have been known to trigger the scanners.
While conventional X-ray scanners can identify broadly whether an object is metal or organic, they cannot determine the exact substance. This can lead to false alarms and slower security checks. However, researchers at Nottingham Trent and Cranfield Universities are developing a new type of X-ray machine that can identify the precise material composition of an object, including hidden explosives or illegal drugs.

Scanners cannot determine the exact composition of an object
While airport scanners can detect both metallic and non-metallic objects, they cannot determine an object's exact composition. They can, however, tell if an object is organic or metallic, or whether it is low or high density. This means that while they can detect gold, they cannot differentiate it from other similarly dense objects like tungsten or platinum.
Airport scanners produce images in orange, blue, and green, with each color corresponding to a category of material. Orange represents organic material, such as food, paper, or marijuana. Green denotes medium-dense non-organic materials, such as plastic bottles, while blue indicates metals or hard plastics. This color-coding system helps security personnel identify potential threats.
Although scanners cannot determine the exact composition of an object, they can detect an organic mass with a large density, which may indicate the presence of drugs. Airport security personnel are trained to recognize suspicious items and will investigate further if something is flagged.
The current scanners have limitations in distinguishing between threat and benign materials, which can lead to false alarms and slower security checks. However, researchers are developing more advanced X-ray scanners that can identify the precise material composition of an object, improving the accuracy of threat detection.

They can detect an organic mass with a large density, which may be drugs
Modern airport scanners are extremely sophisticated and can detect both metallic and non-metallic items, including organic materials. While they cannot determine the exact composition of an object, they can identify whether it is organic, metallic, or low or high density.
The scanners use X-rays to see through luggage and build detailed images of the items inside. The images are colour-coded, with orange representing organic material, such as food, paper, and marijuana, green representing medium-density non-organic materials, and blue representing metals and hard plastics.
Although airport scanners cannot detect drugs directly, they can detect an organic mass with a large density, which may be drugs. The density of commonly used drugs is well-known to airport security officials, who will investigate any suspicious items by opening luggage for a closer look.
Additionally, backscatter scanners, which are used in major airports in the US, UK, and Europe, can detect both metallic and non-metallic objects, including drugs. These scanners create a detailed view of the body and can identify hidden objects beneath clothing or in luggage.

X-ray scanners produce images in orange, blue, and green, each representing a material category
Airport scanners can detect organic materials, among other things. There are two types of scanners used at airports: full-body scanners, known as millimetre wave scanners, and backscatter X-rays. The latter is designed to show hidden objects under clothing or luggage and can detect both metallic and non-metallic objects. While airport scanners cannot determine an object's exact composition, they can tell if an object is organic or metallic (or low-density or high-density).
The brightness of the colours also plays a role, with darker shades indicating higher-density materials. Security personnel must be well-trained in interpreting X-ray images and understanding the colours to ensure efficient luggage screening and security. The colours may vary depending on the X-ray scanner manufacturer, but the underlying principles remain the same.
