Airport metal detectors use X-rays to scan luggage and passengers' bodies, detecting the presence of metallic and non-metallic objects, as well as organic materials. While these scanners can detect the presence of metal, they are adjusted to ignore minor metal components in clothing, the human body, and teeth, focusing instead on larger items. This raises the question of whether airport metal detectors can detect coins swallowed and contained within a person's stomach, and if so, what actions would be taken by security personnel in response.
| Characteristics | Values |
|---|---|
| Can airport metal detectors detect coins in your stomach? | No, but they can detect small amounts of metal. |
| How do they work? | They send a signal from one side of the booth to the other, which is reflected back to a receiver. Metal disrupts the signal, triggering the detector. |
| What type of metal can they detect? | Any type of metal, including gold, platinum, and steel. |
| Are there factors that affect detectability? | Yes, the size, amount, shape, and design of the metal object can affect whether it is detected. |
| Can they detect non-metallic objects? | Yes, they can detect organic materials and differentiate between metallic and non-metallic objects. |
| Can they detect drugs? | No, but they can provide visual clues of drugs hidden in baggage or on a person. |

What You'll Learn
Airport scanners can detect metallic and non-metallic objects
Airport scanners have come a long way and can detect metallic and non-metallic objects. Metal detectors at airports use magnetic fields to identify metal objects. When metal objects are present, the magnetic field is reflected back to the machine, which then beeps to alert the TSA agent. Metal detectors can ignore very small amounts of metal, like the button on your jeans or small earrings.
Body scanners at airports use millimeter-wave technology to detect objects concealed on a person's body. They can identify both metallic and non-metallic items, including weapons, explosives, and drugs hidden under clothing. Millimeter-wave machines use non-ionizing radiofrequency waves to detect threats. The machine bounces the waves off the body and back to the machine. These scanners are ideal for large-scale use in airports as they are non-invasive.
Luggage scanners use 3D imaging technology, allowing security personnel to view objects from multiple angles. This helps in identifying hidden compartments or items wrapped in materials designed to evade detection. Airport scanners can see detailed images of your luggage contents, including metallic and non-metallic objects, as well as organic materials. They do this by releasing X-rays that pass through the bag and calculate the mass and density of the contents.
While metal detection remains a priority, non-metallic materials are increasingly being used to create weapons and other threats. Advanced X-ray scanners can identify these items by analyzing their shape, density, and other visual cues. Airport scanners are designed to flag liquids, gels, and aerosols that exceed certain volume limits, as these are common vehicles for explosive substances.
Overall, airport scanners are equipped with advanced imaging technology and detection systems that can identify a wide range of metallic and non-metallic objects, ensuring the safety of passengers and staff.

They can also detect organic materials
Metal detectors at airports are designed to detect metallic objects. They can also identify the presence of metal concealed on a person. For instance, a necklace worn around the neck may not set off the metal detector, but the same necklace balled up in a pocket is more likely to set off the detector.
However, modern security risks involve materials that do not trigger traditional metal detectors, such as plastics and ceramics. Advanced X-ray scanners at airports can detect not only metallic objects but also non-metallic objects and organic materials. They can calculate the mass and density of the contents of luggage and identify suspicious items. While they may not always be able to establish what the objects are, they can detect the presence of organic materials.
X-ray scanners can identify the shape, density, and other visual cues of items in luggage. They can detect not only metallic objects but also non-metallic objects such as plastics, ceramics, and organic materials. This is particularly important for detecting weapons and explosive components made from non-metallic materials.
Organic materials such as drugs, food, explosives, and paper are marked with an orange colour. Even if the scanners cannot determine the exact composition of an object, they can tell if it is organic or metallic and whether it has a low or high density. This capability is critical for detecting explosives, which can be composed of a wide variety of materials, many of which are organic.
Powdered substances can also be detected by airport scanners, which are equipped to analyze powders and ensure that substances like drugs or bomb-making materials do not pass through security unnoticed. Millimeter-wave scanners are used to detect objects concealed on a person's body, including metallic and non-metallic items such as weapons, explosives, and drugs hidden under clothing.

Gold jewellery may set off a metal detector
Metal detectors at airports are designed to detect a range of metallic items to maintain security. They do this by generating a magnetic field that identifies metal objects on a person. The sensitivity of these detectors can vary, influencing whether certain metals, including gold, set off alarms. Pure gold is a non-ferrous metal, meaning it is not magnetic. As a result, small and simple gold jewellery pieces, such as gold stud earrings or wedding bands, typically do not set off standard airport metal detectors. However, several factors can influence whether gold jewellery sets off airport metal detectors.
Firstly, the size and bulkiness of the jewellery piece matter. Oversized or chunky jewellery pieces are more likely to be detected. Secondly, the metal composition of the jewellery can play a role. Jewellery that combines gold with other metals, especially magnetic ones, can increase the likelihood of detection. Thirdly, layering multiple pieces of gold jewellery together may collectively set off detectors, even if each piece individually would not.
The Transportation Security Administration (TSA) does not require passengers to remove fine jewellery when passing through security checkpoints. They advise that small pieces are generally acceptable to wear through detectors. However, they recommend placing bulky jewellery in carry-on luggage to prevent potential alarms and the need for additional screening.
It is important to note that the design of the gold jewellery can also affect whether it sets off metal detectors. For example, a solid gold bracelet is more likely to set off the detector than a linked bracelet with gaps that show it is not a large piece of solid metal. Additionally, the body scanner is not specifically looking for metal. Instead, it is designed to detect extra material of any kind, including non-metallic objects. Therefore, the way you wear your jewellery can also make a difference. For instance, wearing a necklace around your neck or wrist may not set off the metal detector, but holding or balled up in your hand or pocket might.

Metal detectors can locate metal items
The sensitivity of metal detectors varies, and they are adjusted to detect larger items rather than every tiny piece of metal. For example, a necklace worn around the neck may not trigger the detector, but a balled-up necklace in a pocket is more likely to alarm. Similarly, the design of metal objects matters; a solid bracelet is more likely to set off a detector than a linked one due to the gaps.
Additionally, the location of metal items is displayed on the detector, with older machines using rows of LEDs along the top and side to indicate the X and Y axis of the metal object. Newer machines use remote displays, often superimposing the information over an image of the person. This technology can also be used to locate metal items in the body, such as coins.
While metal detectors can locate metal items, the presence of metal does not always indicate danger. Operators use their judgment to assess the situation. For example, if the machine detects metal on a person's wrist, the operator can verify that it is a watch and decide to take no further action. Similarly, if someone is suspected of swallowing drugs, a full-body X-ray machine can be used to detect packages in the stomach, regardless of the packaging material.
In summary, metal detectors at airports can detect metal items, including coins, in a person's stomach. The technology has advanced to provide detailed images and locate metal objects, assisting operators in making informed decisions about potential security risks.
