Many travelers, especially those who menstruate, have expressed concern about the level of detail that airport X-ray machines and body scanners can detect. While airport luggage scanners can detect any item in a bag, including tampons, the full-body scanners used on passengers are unable to detect tampons or other period products. This is because the scanners do not detect items inside a person's body or penetrate the skin. While older machines produced detailed body scans, today's machines produce generic doll-like scans that protect the privacy of the person being scanned.

What You'll Learn
Full-body scanners use Advanced Imaging Technology (AIT)
Full-body scanners, also known as Advanced Imaging Technology (AIT), use non-ionizing electromagnetic radiation to scan passengers for potential threats, including metallic and non-metallic objects. This technology was introduced in 2007 to supplement metal detectors, pat-downs, and X-ray machines.
AIT uses millimeter wave or backscatter imaging technology to visualize a person's body and any concealed objects without requiring physical contact or the removal of clothing. The millimeter waves are directed at a passenger's body, penetrating their clothing and reflecting off their skin and any concealed items. The reflected waves are then interpreted by the machine to generate an image.
Over the years, full-body scanner technology has evolved to address privacy concerns. Initial backscatter machines displayed uncensored images of the naked body, raising concerns about civil liberties and leading to discussions of "virtual strip searches". In response, newer millimeter wave devices now show a generic, cartoon-like, or "doll-like" representation of a human body, addressing the issue of visual intrusiveness.
Despite these advancements, some passengers may still feel uncomfortable with full-body scanners. As a result, the Transportation Security Administration (TSA) allows passengers to decline AIT screening and opt for alternative methods such as physical pat-downs or removal of clothing. However, in certain situations, the TSA may mandate AIT screening for some passengers to safeguard transportation security.
It is important to note that full-body scanners cannot detect items inside a person's body or body cavities, including tampons or period products. These scanners are designed to identify potential threats located on the body or hidden underneath clothing.

X-ray machines cannot detect items inside the body
X-ray machines are a common tool used in medical settings to generate images of tissues and structures inside the body. They are often used to diagnose broken bones, dental issues, injuries, disorders, and diseases. While X-ray machines can provide valuable insights into the internal workings of the body, there are certain limitations to their capabilities.
X-ray scans are not capable of detecting items inside the body. This includes items such as tampons or other period products. This is because X-ray machines create images based on the reflection of waves off the skin and other objects outside the body. The waves are then interpreted by the machine to create an image. As a result, the machines only capture external images and cannot see what is inside a person's body.
This limitation of X-ray technology has been a concern for airport security, where the use of X-ray body scanners is common. In the past, these scanners produced highly detailed images, often displaying nudity, which raised privacy concerns among passengers. However, advancements in technology have addressed these issues. Today, airport X-ray machines are equipped with privacy software that generates generic, "doll-like" scans of the human body.
It is important to note that while X-ray machines cannot detect items inside the body, they are still effective in identifying metallic and non-metallic threats. The machines use Advanced Imaging Technology (AIT) and millimeter-wave scanners to detect potential threats in a matter of seconds. This technology ensures that security personnel can maintain high levels of safety without compromising the privacy of passengers.
While X-ray machines have their limitations in detecting internal items, they continue to play a crucial role in various fields, including medicine and security. The ongoing advancements in technology contribute to enhancing the effectiveness and privacy protections offered by these machines.

Scanners produce generic body images
Airport body scanners use Advanced Imaging Technology (AIT) to detect metallic and non-metallic threats. These machines send millimetre waves towards a passenger's insides, which reflect off the skin and bounce back an image. While this technology can detect items hidden under clothing, it cannot detect anything inside the body. This means that airport scanners cannot detect tampons, and security will only see what is in your pockets.
In the past, airport scanners produced detailed body scans, displaying nudity. This caused widespread privacy concerns and public outrage, resulting in a lawsuit in 2010 to stop body scanning. However, technology has been evolving since 2013, and today, airport scanners produce more generic, doll-like scans to replicate a generic human body. This privacy software ensures that officers only see a generic outline with a green 'clear' or red 'stop and check' signal. If something is detected in a passenger's pockets, the machine will indicate this by placing an alarm note in the paper doll's groin region.
Millimetre wave scanners use high-frequency radio waves to produce images of the body. These radio waves are absorbed by the body and create a three-dimensional image. Unlike backscatter X-ray scanners, millimetre wave scanners do not use ionizing radiation and are considered safe for the human body. They do not produce images with identifying characteristics of the scanned person but instead use a generic outline.
Backscatter X-ray scanners use extra low-dose X-rays to produce images of the body. The X-rays are reflected off the skin and clothing and picked up by detectors. These scanners can detect items hidden under clothing but not inside the body. Transmission X-ray scanners, on the other hand, emit X-rays that penetrate the body and produce an image on the other side. These images can reveal items hidden under clothing or inside body cavities.
While airport scanners produce generic body images, it is important to note that there have been concerns about the privacy of these scans. In 2010, it was revealed that the US Marshal Service operated a backscatter machine that recorded images of individuals. Additionally, an online poll in 2010 showed that 59.41% of respondents would not fly due to the new scans, indicating ongoing privacy concerns.

Scanners can detect some hygiene products
Airport body scanners use Advanced Imaging Technology (AIT) for full-body scans at checkpoints. They use radiofrequency waves to locate unknown objects on passengers. The scanners are designed to detect a wide range of metallic and non-metallic threats.
The technology used in these scanners is typically harmless. David Brenner, a radiation biophysics professor at Columbia University Medical Center, stated that "there's no plausible evidence by which millimeter waves could damage DNA." Other medical experts affirmed that the risks associated with the scanners are negligible.
While the scanners are unable to detect items inside a person's body, they can detect some hygiene products. The scanners use X-ray technology to sense the shadows cast by objects in luggage. The shape and darkness of these shadows are used to distinguish between different items. However, the scanners used for full-body scans cannot detect tampons or menstrual cups.
In the past, airport scanners have raised privacy concerns. Early versions of the scanners displayed naked images of passengers, which were accessible to checkpoint staff. However, these scanners have been replaced by generic images of a human body, with privacy software installed.

Millimeter wave machines have privacy software installed
Airport body scanners use Advanced Imaging Technology (AIT) to detect metallic and non-metallic threats. These machines use millimeter waves that reflect off a passenger's skin and bounce back an image, which is then interpreted by the machine. While these machines do not invade the privacy of passengers by showing intimate details, early versions of the scanners did not have privacy protections in place, and officers were able to view naked images of passengers.
To address privacy concerns, millimeter wave machines have been updated with privacy software. This software generates a generic image of a body, rather than the passenger's unique image. The image is often a doll-like scan that replicates a generic human body. The software also includes a privacy algorithm to blur certain regions of the image, such as genitals and faces, while highlighting potential threat areas. This is done by using automated target recognition (ATR) software, which produces a generic outline of a person, with any suspicious areas highlighted. If no suspicious items are found, a green screen appears, indicating that the passenger is cleared.
The TSA has taken steps to address privacy concerns by installing this software, which either creates generic outlines of people or blurs certain regions of the image. This software upgrade was enough to ease the public's concerns about the machines. The European Union has also addressed privacy concerns by banning any body scanners that use X-ray technology, as this type of scanner can reveal intimate details.
While the software installed on millimeter wave machines helps to protect passenger privacy, there are still concerns about the capture and dissemination of images. Reports have emerged of full-body scanner images being improperly saved and shared. Additionally, some passengers may still object to being viewed in a state of undress, even if the image is not retrievable by the agent next to the machine.
