Airport security systems use a variety of methods to ensure the safety of travellers, including metal detectors, backscatter X-ray machines, millimeter wave scanners, and cabinet X-ray machines. These scanners can detect metallic and non-metallic items, such as weapons and explosives, by sending waves or X-rays through clothing and reflecting them off the passenger's skin. While these scanners are effective at detecting potential threats, they may also be activated by certain personal items, such as bandages. This raises the question: can airport scanners detect bandages, and if so, what are the implications for travellers who require bandages for medical reasons?

What You'll Learn
Airport scanners can detect bandages
Airport scanners use various methods and technologies to ensure the safety of passengers. Metal detectors, millimeter wave machines, ionizing radiation machines, backscatter scanners, and cabinet x-ray scanners are some examples of these scanners.
Millimeter wave scanners emit extremely low-energy waves, capturing the reflected energy. They can pass through a single layer of clothing and "see" what's underneath. These scanners are used to detect threats and items in violation of TSA carry-on rules, such as weapons and explosive materials. They can detect a wide range of metallic and non-metallic items, including bandages, female hygiene products, and other anomalies and bulges on the body.
Backscatter scanners, on the other hand, use very low-dose x-rays, similar to those used in medical imaging, to detect threats such as weapons or explosives hidden under clothing. These scanners work by interacting with materials of different densities, allowing them to see denser objects, such as bones, inside the human body.
While airport scanners are effective at detecting potential threats, they cannot detect everything. For example, they are unable to detect inflammation or cancer, and they cannot see inside bodily cavities, so some drug-smuggling tactics may go undetected.
It is important to note that while these scanners may detect bandages, it does not necessarily mean that you will be stopped and searched. The detection of bandages may trigger further investigation, such as a pat-down search, to confirm the presence of any prohibited items.

They can also detect metallic and non-metallic objects
Airport body scanners are designed to detect both metallic and non-metallic objects. They use advanced imaging technology (AIT) for full-body scans at airport checkpoints. The scanners emit millimeter waves, which pass through clothing and reflect off the skin and any concealed objects, creating an image that is then interpreted by the machine.
The scanners can detect a wide range of metallic and non-metallic threats, including weapons and explosives. They can identify steel and non-metallic compounds on the body's exterior. For example, they can detect firearms, knives, and other metallic objects, as well as non-metallic weapons, plastic or chemical explosives, and drugs concealed in the body.
However, it is important to note that airport scanners cannot detect all types of objects. They are unable to see inside bodily cavities, and there are limitations to their ability to detect certain materials. For instance, tampons are invisible to airport scanners, and some non-metal objects may not always be detected. Inconsistencies in fabric density may suggest the presence of a suspicious object, but it is unclear exactly when non-metal items will set off the scanner.
Additionally, airport scanners are not able to detect medical conditions or diseases. They can detect some anomalies and bulges, such as skin growths, implants, colostomy bags, and other metallic or non-metallic body protrusions. However, they cannot detect inflammation, hernias, or cancer.
Overall, while airport scanners are effective at detecting a wide range of metallic and non-metallic objects, they have limitations and cannot identify all types of threats or medical conditions.

They can detect weapons and explosives
Airport body scanners are designed to detect metallic and non-metallic threat items, such as weapons and explosives. They can detect firearms, knives, and other metallic objects. They can also detect non-metallic weapons and plastic or chemical explosives concealed in pockets or worn on the body.
Millimeter wave scanners emit extremely low-energy waves and capture the reflected energy. They use non-ionizing radiofrequency waves to detect threats. The machine bounces the waves off the body and back to the machine. If there are no weapons or other potential threats when someone is scanned, the screen turns green and shows an “OK”. If an object is detected, it will appear on the screen along with a generic body outline to show the location.
Backscatter x-ray scanners, the more common type of scanner in the US, utilize very low-dose x-rays, similar to those used in medical imaging. They can detect threats such as weapons or explosives that a person could be carrying under their clothing.
While body scanners are designed to detect weapons and explosives, they are not infallible. They can malfunction, and alarms can go off without good reason. They also cannot detect objects hidden inside bodily cavities.

They cannot detect objects inside the body
Airport body scanners are designed to detect threats, such as weapons, and items in violation of TSA carry-on rules. They use advanced imaging technology (AIT) for full-body scans and can detect a wide range of metallic and non-metallic objects. However, they cannot detect objects inside the body.
The scanners use millimeter wave machines that emit extremely low-energy waves to detect objects. These waves pass through clothing and reflect off the passenger's skin and any concealed items, creating an image interpreted by the machine. While these scanners can detect items like tampons or menstrual cups, they cannot see inside bodily cavities.
Millimeter wave machines use non-ionizing radiofrequency waves, which are reflected back to the machine, to detect threats. If there are no weapons or other potential threats, the screen turns green and shows an "OK." If an object is detected, it appears on the screen with a generic body outline to indicate its location.
While airport body scanners can detect some medical issues, such as skin growths, implants, and colostomy bags, they cannot detect serious medical conditions like cancer, hernias, or inflammation. They are also unable to detect objects concealed inside body cavities, which has allowed at least one prevalent drug smuggling tactic to go undetected.
In conclusion, while airport body scanners are effective at detecting various metallic and non-metallic threats, they have limitations and cannot detect objects inside the body.

They use low-energy, non-ionizing radiation
Airport security systems use a variety of technologies to ensure the safety of passengers and crew. These include metal detectors, backscatter X-ray machines, millimeter wave scanners, and cabinet X-ray machines. Some of these machines use ionizing radiation to scan passengers and their luggage, while others use non-ionizing radiation.
Metal detectors and millimeter wave machines use low-energy, non-ionizing radiation to scan surfaces. The energy that bounces back from the scanned surface will show the objects that are present, or it can generate an image that TSA agents can use to identify items that may need further investigation. Millimeter wave machines use non-ionizing radiofrequency waves to detect threats. The machine bounces the waves off the body and back to the machine. Millimeter wave scanners emit far less energy than a cell phone, and they are important because they can detect hidden threats such as guns and knives. If there are no weapons or other potential threats, the screen turns green and shows an "OK." If an object is detected, it will appear on the screen along with a generic body outline to indicate the location. Millimeter wave scanners do not generate ionizing radiation.
Backscatter passenger scanners, on the other hand, use very low-energy X-rays (ionizing radiation) to detect threats such as weapons or explosives that a person could be carrying under their clothing. The amount of radiation received from a backscatter machine is generally equivalent to the amount of cosmic radiation one would be exposed to during two minutes of flight, and the risk of health effects is considered very low. Cabinet X-ray systems, used to screen luggage and carry-on items, have enclosed cabinets with thick walls and lead curtains at entry and exit points to prevent radiation from escaping.
While airport scanners can detect a wide range of items, including weapons, explosives, liquids, sharp objects, and pills, they cannot detect everything. For example, scanners generally cannot identify items hidden within body cavities, and they cannot detect inflammation or cancer. Additionally, certain items such as tampons and bandages are invisible to airport scanners.
