Airport body scanners use Advanced Imaging Technology (AIT) to detect metallic and non-metallic threats. The technology uses millimetre waves to scan a passenger's insides, with the waves reflecting off the skin and other objects to create an image. However, these scanners do not see under the skin, so they cannot detect items stashed inside body cavities, such as drugs or hazardous liquids. This means that airport scanners cannot see inside your anus.

What You'll Learn
Airport body scanners use Advanced Imaging Technology (AIT)
AIT scanners are considered safe for passengers, emitting energy levels that are 10,000 times lower than those of a standard cellphone. They do not see under the skin, so they cannot detect items stashed inside body cavities. However, they can detect items hidden in pockets or on the body, including non-metallic objects. This technology is an important tool for airport security, providing a quick and effective way to identify potential threats without causing harm to passengers.
The use of AIT scanners has raised concerns about privacy and safety. Some people worry that the scanners create images that amount to virtual strip searches, especially for minors, which may violate child pornography laws. There have also been concerns about radiation exposure, as some airport security systems use ionizing radiation, which has higher energy levels and can be harmful in high doses. However, AIT scanners use non-ionizing radiation, and the energy emitted is well within safe limits.
While AIT scanners are widely used, they are not the only technology employed for security screening at airports. Metal detectors, for example, use magnetic fields to detect metal objects, and other whole-body imaging (WBI) technologies, such as backscatter X-ray scanners, are also utilized. Alternative screening methods, such as chemical-based scanners, bomb-sniffing dogs, and passenger profiling, have been suggested by experts as potentially more effective approaches to security.
The implementation of AIT scanners and other security measures at airports reflects the ongoing efforts to balance safety and efficiency in air travel. While these technologies raise valid concerns about privacy and radiation exposure, they also play a crucial role in ensuring the security of passengers and staff. As technology advances, we can expect further developments and enhancements in airport security systems, aiming to address both safety threats and privacy considerations.

Scanners use non-ionizing radiation, which is safe
Airport body scanners use advanced imaging technology (AIT) to detect metallic and non-metallic objects on passengers. These machines use non-ionizing radiation to scan passengers and ensure they are not carrying any hidden items. Non-ionizing radiation does not have enough energy to remove electrons from atoms, but it can move atoms in a molecule around or cause them to vibrate. This type of radiation is considered safe for passengers and is much less harmful than ionizing radiation, which can cause cancer and other health problems.
While airport scanners can see under clothing, they do not see under the skin. This means that items stashed inside body cavities, such as drugs or hazardous liquids, would not be detected by the scanner. However, these items may be detected if they are in a passenger's pockets. The waves from the scanner bounce off the passenger's skin and create an image that is interpreted by the machine, looking for potential threats.
Millimeter-wave machines, a type of body scanner, emit far less energy than a cellphone. The FDA's Center for Devices and Radiological Health (CDRH) ensures that all x-ray systems and radiation-emitting screening equipment are built to use radiation safely. These machines are calibrated and maintained to ensure safety. The energy emitted by millimeter-wave technology is 10,000 times less than what is permitted by a standard cellphone.
While there may be concerns about frequent flyers being exposed to radiation regularly, the doses of radiation from security scanners are very small and cannot cause any short-term tissue damage. The potential increase in cancer risk from security scanners is likely negligible and cannot be accurately estimated. The annual dose of radiation for a frequent flyer who is scanned three times a day using the backscatter technique is about 0.3 millisievert, which is below the limit set for the general public.

Scanners detect metallic and non-metallic threats
Airport body scanners use Advanced Imaging Technology (AIT) to detect a wide range of metallic and non-metallic threats. These scanners use millimetre waves, a form of non-ionizing radiation, to scan the body. The waves reflect off the skin and bounce back an image to the machine, which is then interpreted by the software. The software can detect metallic and non-metallic items hidden under clothing and highlight them as potential threats.
While body scanners can detect items hidden in pockets, they do not see under the skin. Therefore, they will not pick up items stashed inside body cavities. However, some full-body scanners, such as backscatter X-ray scanners, can detect items hidden in body cavities. These scanners use low-dose radiation to detect metallic and non-metallic objects hidden under clothing, in shoes, and in body cavities.
To address safety concerns, some countries have banned backscatter X-ray scanners. Instead, passive infrared scanners have been developed for use in public spaces. These scanners collect and analyze the natural heat radiation emitted by the human body to detect metallic and non-metallic threat objects. They do not use an external radiation source and preserve privacy as no body details are revealed.
Hand-held metal detectors, such as the Super Scanner V, are also used for security screening. These devices detect a wide range of metallic objects, including weapons, and provide clear, immediate feedback when a potential threat is detected.

Scanners cannot see inside body cavities
It is understandable that stepping into an airport body scanner can be an uncomfortable experience. The machines use Advanced Imaging Technology (AIT) and work by sending millimetre waves towards a passenger's insides. While this may sound alarming, it is important to note that these waves are safe and emit much less energy than, for example, UV rays from the sun or a tanning bed. In fact, the energy emitted is 10,000 times less than what is permitted by a standard cellphone.
So, what can these scanners see? Well, according to TSA spokesperson R. Carter Langston, the machines use millimetre wave imaging to detect a wide range of metallic and non-metallic threats. This means they can see through clothing and reflect off a passenger's skin, bouncing back an image that is interpreted by the machine.
However, it is important to clarify that these scanners do not see under the skin. Shawna Malvini Redden, PhD, a communication researcher who has studied the TSA since 2010, confirms that body scanners would not pick up anything stashed inside a body cavity. So, while the scanners may reveal the outline of a person's body and any items concealed on their person, they cannot see inside body cavities, including the anus. This means that drugs or hazardous liquids hidden internally would not be detected by the machine.
While the scanners are an important security measure, some passengers may still feel uneasy about the level of detail they reveal. It is worth noting that the TSA has measures in place to minimise the need for invasive pat-downs, especially for children. Additionally, passengers concerned about exposure to millimetre waves can opt for a pat-down instead of walking through the scanner.

The waves do not penetrate the body and are reflected off the skin, so they cannot see inside body cavities. This means that airport scanners cannot see inside a person's anus.

TSA spokesperson R. Carter Langston also assures passengers that the AIT scanners are safe and cannot see anything inside the body, including tampons or other items. The energy emitted by millimetre wave technology is significantly less than that of standard cellphones, so passengers don't need to worry about exposure to harmful radiation.
