Airport body scanners use Advanced Imaging Technology (AIT) and millimeter wave technology to detect metallic and non-metallic objects on a person's body. They do not reveal a person's naked body or the insides of their body. While they are safe for people with pacemakers and breast implants, they can detect sanitary napkins, panty liners, and adult diapers as potential threat items. This may result in additional screening, including a pat-down. While some travelers have reported that body scanners have identified their menstrual pads, others claim that these scanners do not set off any alarms.

What You'll Learn
Body scanners can detect pads
Body scanners at airports use Advanced Imaging Technology (AIT) and millimeter wave technology to detect a wide range of metallic and non-metallic objects. These scanners are designed to identify potential threats, such as weapons or items that violate carry-on rules. While they do not reveal a person's naked body or their insides, they can detect items such as pads and menstrual products.
The scanners generate a generic image of a body, without specific identifying features, to ensure passenger privacy. If a potential threat item is detected, it will be indicated on this generic outline, and additional screening may be required. This could include a pat-down, which will be conducted by an officer of the same gender, with the option of a private screening.
While body scanners can detect pads, it is important to note that they are commonly used and security personnel are accustomed to seeing them. The scanners are primarily focused on identifying items that may pose a security risk. In most cases, pads will not set off any alarms or lead to additional screening. However, there have been rare instances where individuals wearing pads or adult incontinence products have been subjected to further screening or pat-downs.
Body scanners are safe for individuals with medical conditions or devices, such as pacemakers or defibrillators. The millimeter waves used in the scanners do not penetrate the body and the scan time is very short, reducing any potential interference risks. Additionally, the scanners are safe for pregnant individuals and those with surgical implants, such as titanium hips or plates and screws.
In summary, while body scanners can detect pads, it is a routine occurrence, and security personnel are trained to handle such situations discreetly and efficiently. The scanners prioritize the detection of security threats, and the privacy of passengers is maintained throughout the process.

Scanners cannot see inside the body
Airport body scanners are used to detect objects on or inside a person's body for security screening purposes, without physically removing clothes or making physical contact. The scanners use Advanced Imaging Technology (AIT) and are millimetre wave scanners that detect a wide range of metallic and non-metallic threats.
Despite the technology used, the scanners cannot see inside the body. According to Eri Jenkins, an advisor who previously worked in uniform at a TSA checkpoint, "The body scanners cannot see anything inside of the body, including tampons or any other items." The body scanners provide a nondescript avatar image of the human anatomy. This is confirmed by TSA spokesperson R. Carter Langston, who states that "millimetre wave imaging technology does not detect items inside a passenger's body or penetrate the skin".
The scanners are designed to respect passenger privacy while maintaining security effectiveness. The millimetre wave machines do not pick up details such as nipples, genitalia, size, weight, or height. Instead, they generate generic images of a body, with a box representing any detected items. This generic human form is used to ensure passenger privacy.
While the scanners can detect items on the skin or inside clothing, they are not designed to see inside the body. This means that items inside body cavities, such as drugs or hazardous liquids, would not be detected by the scanners.

Scanners do not show a naked body
Airport body scanners use Advanced Imaging Technology (AIT) to detect metallic and non-metallic threats. They do not show a naked body on the screen.
Today's millimeter wave machines don't see nipples or genitalia, and they do not pick up size, weight, or height. They generate generic images of a body, with an outline of a body and a box representing the area where the scanner picked up something. If there is no alarm, officers don't see anything at all—simply a screen reading "OK."
The machines send millimeter waves toward a passenger's insides, and the waves bounce off the person's body. This technology is safe for passengers with pacemakers or defibrillators. The energy emitted by millimeter wave technology is 10,000 times less than what is permitted by a standard cellphone.
In the past, airport body scanners did produce very detailed images of passengers' bodies, amounting to essentially nude photographs. However, these machines were removed from all airports in 2013 due to privacy and health concerns.

Scanners are safe for pacemakers
Millimetre wave body scanners, which are used in most airports, emit millimetre waves that bounce off the skin to create an image of the body and any concealed items. These scanners are safe for patients with pacemakers and defibrillators, according to a study by the European Society of Cardiology. The study included 300 patients with pacemakers, implantable cardioverter defibrillators (ICDs), or cardiac resynchronisation therapy (CRT) devices, who underwent millimetre wave body scans at the German Heart Centre Munich. An electrocardiogram (ECG) was recorded during the scan to detect potential malfunctions of the cardiac device caused by electromagnetic interference. The study found no evidence of electromagnetic interference or device malfunction, and concluded that scanning is safe for patients with implanted cardiac devices.
The premise of the study was that the electromagnetic fields generated by body scanners could be misinterpreted by cardiac devices as signals from the heart, causing a pacemaker to stop pacing or pace incorrectly, or a defibrillator to deliver shock therapy. However, the research found no indication of electromagnetic interference or device malfunction. The study's author, Dr Carsten Lennerz, suggested that cardiac devices may filter out high-frequency signals such as millimetre waves, which barely penetrate the body and have a very short scan time.
Based on the study's findings, Dr Lennerz concluded that millimetre wave body scanners pose no threat to patients with pacemakers, ICDs, and CRT devices, and that there is no need for specific protocols or restrictions on their use. The American College of Cardiology also affirms that body scanners used at airports and other public places for security screening are safe for patients with pacemakers, ICDs, and CRT devices.
While airport body scanners can detect a wide range of metallic and non-metallic threats, they are not known to detect items inside the body. They are designed to detect items on a person, not in a person, so they are unable to detect drugs or other dangerous substances inside body cavities.

Scanners are not always accurate
In addition, there have been instances where people have managed to conceal metallic objects by sewing them into their clothing. For example, in 2012, a civil rights attorney named John Corbett sewed a small metal can into the side of his shirt and claimed that the scanner did not detect it.
Furthermore, whole-body scans can often produce "incidental findings" that doctors don't know how to interpret, leading to unnecessary anxiety and invasive testing for patients. The radiation exposure associated with CT scans is also a concern, although MRI scans, which don't expose individuals to radiation, are now more commonly used for whole-body scans.
While millimeter wave scanners used in airports do not generate ionizing radiation, the health risks posed by these machines are still being studied, and the evidence is mixed. Some countries have banned backscatter X-ray scanners due to safety concerns.
It is important to note that the accuracy and safety of body scanners are constantly being improved, and most people can refuse a scan and opt for a traditional pat-down if they have concerns.
