Airport security systems use metal detectors, backscatter X-ray machines, millimeter wave scanners, and cabinet X-ray machines to ensure the safety of passengers, crew, and aircraft. These machines are designed to detect narcotics, drugs, weapons, and other contraband. While older full-body scanners revealed naked images of passengers, newer machines use avatars to ensure privacy. They generate generic images of a body with boxes representing areas of interest, such as foreign objects or anomalies. It is unclear whether Nuvaring, a contraceptive vaginal ring, would be detected or visible on airport scanners, but it is essential to consider that it may be considered a foreign object and prompt further inspection.

What You'll Learn
Can airport scanners see inside the body?
Airport body scanners use advanced imaging technology (AIT) for full-body scans at airport checkpoints. These machines use millimeter wave scanners that detect metallic and non-metallic objects in a matter of seconds. The waves reflect off the passenger's skin and bounce back an image, which is interpreted by the machine.
While the technology is designed to respect passengers' privacy, there have been instances where TSA agents have been able to detect items such as menstrual cups, pads, and tampons, which has caused embarrassment for some passengers. In addition, transgender individuals may experience delays or feelings of harassment due to technology limitations that cause certain body parts to light up on the scan.
Despite these concerns, TSA agents do not see inside the body. The machines are designed to respect privacy and only generate generic images of a body, with a box representing any areas of concern. The waves used in the scanners do not penetrate the skin, and the amount of radiation emitted is far less than that of a cell phone.
In terms of the NuvaRing, it is unlikely that airport scanners would be able to detect it. The NuvaRing is a small, flexible ring that is inserted into the vagina and left in place for three weeks at a time. It is a form of hormonal birth control that releases a low dose of progestin and estrogen. While airport scanners can detect metal and non-metal objects, the NuvaRing is made of a soft, flexible plastic and would not be visible to the scanners.

Do airport scanners show nudity?
Airport body scanners use a technology called Advanced Imaging Technology (AIT) for full-body scans at airport checkpoints. They use non-ionizing radiation to scan travellers and ensure that they are not carrying hidden items.
Today's millimeter wave machines do not show nudity. They do not see nipples or genitalia, and they do not pick up size, weight, or height. When passengers are scanned, the machines generate generic images of a body instead of the passenger's unique image. It is simply an outline of a body with a box representing the area where the scanner picked up something.
However, there have been reports of TSA full-body scanners detecting menstrual cups, pads, tampons, and other "foreign objects" in the pelvic region. In these cases, the monitor may show a body outline with a red or yellow mark over the genital area. While this does not reveal nudity, it can still be an invasive and embarrassing experience for passengers.
It is important to note that some older versions of the scanners did not have privacy protections, and officers were able to view naked images of passengers. These machines were removed from all airports in 2013 due to privacy and health concerns.
Regarding the detection of specific items such as NuvaRing, there is limited information available. It is possible that it could be detected by the scanners, but it is unlikely to be considered a threat or cause for further investigation.

What items trigger airport scanners?
Airport security systems use metal detectors, backscatter X-ray machines, millimeter wave scanners, and cabinet X-ray machines to ensure the safety of passengers and staff. Some security devices use ionizing radiation to scan luggage and identify objects that may be hidden by passengers, while others use non-ionizing radiation to scan travellers and ensure they are not carrying prohibited items.
Metal detectors and millimeter wave machines use low-energy, non-ionizing radiation to scan surfaces. The energy that bounces back will show the objects present, or it can generate an image that TSA agents can use to identify items that need further investigation. Millimeter wave machines use non-ionizing radiofrequency waves to detect threats and bounce the waves off the body and back to the machine. These scanners emit far less energy than a cell phone.
Backscatter X-ray machines use very low-energy X-rays 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 the same amount of cosmic radiation received during two minutes of flight, and the risk of health effects is very low.
Airport body scanners alert TSOs to threats, mainly weapons, or items in violation of TSA carry-on rules. They are designed to detect "metallic and nonmetallic threat items." These scanners can detect benign items such as hair clips, thick hair, and other items that passengers are required to put in bins before walking through security checkpoints. If you have anything on your body that you think will set off the alarms, such as a medical device, it is important to inform the TSO before entering the scanner.
Airport baggage scanners can see detailed images of luggage contents, including metallic and non-metallic objects, as well as organic materials. They can detect the density and mass of packed objects, but they are not always able to establish what the objects are. They can detect money, the smallest amounts of metal, and paper.
Regarding NuvaRing, while there are no explicit mentions of it being detected by airport scanners, similar products such as menstrual cups have been detected by full-body scanners.

How do airport scanners work?
Airport scanners have become an integral part of airport security, designed to detect potential threats and ensure the safety of passengers and crew. These machines employ a variety of technologies, including X-rays and millimeter wave technology, to scan passengers, their luggage, and belongings for prohibited items.
X-ray scanners use low levels of ionizing radiation to create images of the contents of a passenger's luggage. Cabinet X-ray systems, for instance, are used to screen luggage and carry-on items. They have thick walls, lead curtains, locks, warning lights, and labels to prevent radiation from escaping and ensure safe operation. Backscatter X-ray machines, another type of X-ray scanner, detect threats such as weapons or explosives hidden under clothing. These machines use very low-energy X-rays reflected back to the machine, emitting radiation levels comparable to two minutes of cosmic radiation during a flight, thus posing a very low health risk.
Millimeter wave scanners, on the other hand, use non-ionizing electromagnetic radiation in the extremely high-frequency radio band, similar to wireless data transmitters. These machines emit far less energy than a cell phone and are considered safe for passengers, operating below recommended safety limits. They detect a wide range of items, including weapons, explosives, liquids, sharp objects, and pills, by bouncing waves off the body and back to the machine. If no threats are detected, the screen turns green and displays an "OK" message. If an object is found, it is indicated on the screen with a generic body outline to show its location.
Advanced Imaging Technology (AIT) is used in full-body scans at airport checkpoints. These scanners can detect objects inside a person's body, including swallowed items or those hidden in body cavities. They address privacy concerns by generating generic body outlines rather than detailed images. Passengers who wish to avoid these scanners due to privacy or health concerns can opt for a pat-down search instead.
Overall, airport scanners utilize a combination of X-ray and millimeter wave technologies to ensure the safety of air travel by detecting potential threats on passengers, in their luggage, or carry-on items.

What are airport scanners looking for?
Airport scanners are primarily looking for items that could be potential threats, such as weapons, explosives, or other items that are not approved for air travel. These scanners use advanced imaging technology (AIT) to detect both metallic and non-metallic objects, including organic materials such as drugs, food, explosives, or paper.
While older scanners may have revealed detailed images of a person's naked body, privacy concerns have led to the adoption of generic avatar images that ensure privacy for passengers. Today's millimeter wave machines do not reveal nipples or genitalia and do not capture size, weight, or height. Instead, they generate a generic outline of a body with a box indicating the area where the scanner detected something.
Additionally, airport scanners can detect even the smallest amounts of metal. Metal detectors are designed to ignore very small amounts of metal, such as buttons or earrings, but they can still detect larger items.
It's important to note that some airport scanners use ionizing radiation, which has high energy levels and can identify objects hidden by passengers, while others use non-ionizing radiation, which has lower energy levels and is safer for passengers.
In terms of what airport scanners can see, they are capable of detecting a wide range of items, including:
- Metal objects, regardless of size
- Organic materials, such as drugs, food, or explosives
- Paper and other non-metallic objects
- Objects hidden under clothing or in luggage
