The Transportation Security Administration (TSA) uses advanced imaging technology (AIT) and walk-through metal detectors to screen passengers for metallic and non-metallic threats, including weapons and explosives. While the TSA's current scanners can detect objects hidden beneath clothing, they do not expose passengers' naked bodies. Instead, they generate a generic, cartoon-like outline of a person, with any anomalies flagged by yellow boxes. This outline respects passengers' privacy while still maintaining security effectiveness.

What You'll Learn
TSA scanners can detect plastic bottles containing pills
The Transportation Security Administration (TSA) uses advanced imaging technology, metal detectors, and pat-downs to screen passengers and their luggage for prohibited items and security threats. While the TSA does not specifically detect drugs, its scanners can identify objects as organic or metallic and determine their density. This means that airport scanners can detect pills in plastic bottles, whether carried on your person or in your luggage.
TSA scanners use millimeter-wave imaging systems and non-ionizing electromagnetic waves to detect potential threats, including weapons and explosives. The technology can identify objects hidden beneath clothing and generate a generic, cartoon-like outline of a person with any anomalies flagged by yellow boxes. This system protects passengers' privacy while still effectively screening for security risks.
When it comes to medications, the TSA allows pills, injectables, and homeopathic remedies in both carry-on and checked baggage. Medications in daily dosage containers are typically screened by X-ray, but passengers can request a visual inspection if preferred. It is recommended to carry medications in their original containers, and some states have specific laws regarding the labeling of prescription medications.
To ensure a smooth screening process, passengers are advised to follow certain guidelines. For example, prescription medications should be limited to personal use quantities, typically no more than a 90-day supply. Additionally, passengers should be prepared for additional screening if carrying medically required liquids, and these liquids must not exceed 3.4 ounces (100ml) in carry-on bags.
In summary, TSA scanners can effectively detect plastic bottles containing pills, whether carried on your person or in your luggage. The TSA employs advanced technology to balance security and privacy, and it is important for passengers to be aware of the guidelines for carrying medications to facilitate a smooth screening experience.

Scanners use non-ionizing electromagnetic waves
The Transportation Security Administration (TSA) uses advanced imaging technology (AIT) paired with automated target recognition (ATR) software to detect both metallic and non-metallic threats. This technology is safe and meets national health and safety standards.
AIT scanners use millimeter wave imaging systems that emit non-ionizing electromagnetic waves to detect potential threats. These waves are much larger than X-rays and do not have enough energy to remove electrons from atoms. As a result, they do not alter the structure of biological molecules such as proteins and nucleic acids. Millimeter-wave scanners produce a generic, cartoon-like outline of a person, with any anomalies flagged by yellow boxes. The scanner does not display a detailed anatomical image, and no private body parts are exposed.
Millimeter wave scanners emit radio waves that pass through clothing and bounce off the skin and any potential threats, returning to an array of receiving antennae. The reflected signals are then post-processed by computer ATR software, which identifies potential targets. This software creates two generic figures (front and back), including spatially identified targets, and sends this information to an operator station.
While millimeter wave scanners are considered safe, they are not without risks. The International Commission on Non-Ionizing Radiation Protection (ICNIRP) has examined data related to potential non-thermal effects, such as changes to the immune system and neurological and behavioral effects. Additionally, concerns have been raised about the high number of false alarms caused by millimeter wave scanners, as they can be fooled by objects that are similar in size to the wavelength of the energy, including folds in clothing, buttons, and beads of sweat.

Scanners can detect metallic and non-metallic items
The Transportation Security Administration (TSA) uses advanced imaging technology (AIT) and walk-through metal detectors to screen passengers. This technology includes backscatter x-ray machines, millimeter wave scanners, and cabinet x-ray machines.
AIT uses millimeter wave imaging systems and non-ionizing electromagnetic waves to detect potential threats. This technology can detect metallic and non-metallic items, including weapons and explosives, which may be concealed under clothing. The scanner generates a generic, cartoon-like outline of a person, with any anomalies flagged by yellow boxes. This allows for the detection of objects without exposing the physical form of the person being scanned.
TSA agents may also use pat-down procedures to determine whether prohibited items or threats are being carried on a person. This may include an inspection of the head, neck, arms, torso, legs, and feet, and may require the adjustment of clothing.
In addition to detecting metallic items, the body scanners can also identify non-metallic items that standard metal detectors might miss, such as plastic explosives or weapons made from non-metallic materials. This ensures that potential threats are identified regardless of their composition.
The TSA is constantly adapting its security measures to meet evolving threats and maintain the highest levels of transportation security. These measures are designed to prevent prohibited items and threats from entering sterile areas of airports and other transportation hubs.

Scanners cannot show detailed body parts
While TSA scanners can detect metallic and non-metallic items, including weapons and explosives, they do not show detailed body parts. The current scanners use millimeter-wave imaging systems and non-ionizing electromagnetic waves to detect potential threats. They generate a generic, cartoon-like outline of a person, with any anomalies flagged by yellow boxes. This outline is the same for everyone, and no private body parts are exposed. The operator never sees your actual physical form, only an anonymized image.
The previous generation of scanners, which used backscatter technology, did display naked images of passengers. However, even with these older machines, the TSA implemented safeguards for passenger privacy. For example, the officer viewing the scan would not be the same person checking passengers at the checkpoint.
Today, millimeter wave machines with privacy software installed show TSOs only a generic avatar image of the human anatomy, with a green 'clear' or red 'stop and check' signal. If something is detected in a passenger's pocket, for instance, the machine will put an alarm note in the avatar's groin region to indicate to the officer where to search. Passengers can also see everything that the TSOs see on the screen, ensuring transparency.
While the TSA is committed to protecting passengers, it also respects their privacy. The implementation of Advanced Imaging Technology (AIT) paired with Automated Target Recognition (ATR) software allows the TSA to balance security with passenger privacy. This technology allows scanners to detect threats without displaying detailed anatomical images.
In addition to privacy concerns, the TSA also offers accommodations for those who are uncomfortable with the scanning process. Passengers can opt out of the body scanner, but this usually results in a physical pat-down, which some may find more uncomfortable. Programs like TSA Cares provide customized assistance for passengers with medical conditions, disabilities, or other needs during the screening process.

Scanners use Advanced Imaging Technology (AIT)
Scanners that use Advanced Imaging Technology (AIT) are an integral part of the Transportation Security Administration's (TSA) effort to ensure travel safety and security. AIT scanners use millimeter-wave technology to detect metallic and non-metallic threats, including weapons and explosives, concealed under clothing. This technology does not expose passengers' private body parts or their actual physical form to the operator. Instead, it generates a generic, cartoon-like outline of a person, with any anomalies flagged by yellow boxes.
AIT has been implemented in response to specific threats, such as the "Shoe Bomber" in 2001 and the "Underwear Bomber" in 2009, and to enhance security measures. It is safe for individuals being screened, meeting national health and safety standards, and has been tested by both the TSA and independent entities. The energy emitted by millimeter-wave technology is 1000 times less than international limits and guidelines.
AIT is used in airports and mass transit systems in several countries, including Canada, the Netherlands, Australia, Nigeria, and the United Kingdom. It is an effective technology for detecting threats and has reduced wait times at TSA checkpoints by providing an alternative screening option for passengers with medical devices or joint replacements that would typically set off metal detectors.
While AIT is generally optional, and passengers can opt for a physical screening or pat-down instead, some passengers may be required to undergo AIT screening if selected for enhanced screening prior to their arrival at the security checkpoint. This occurs in very limited circumstances and affects only a small number of passengers.
