Can Airport Scanners Detect Inflammation?

Airport security is tighter than ever before. Advanced imaging technology allows transportation security officers to see concealed items, but can these scanners also detect medical issues like inflammation?

If you’re short on time, here’s the quick answer: airport scanners like millimeter wave machines and backscatter X-ray devices are designed to detect weapons, explosives and other threats. They cannot diagnose medical conditions or inflammation.

In this comprehensive guide, we’ll look at what exactly airport body scanners can and cannot detect, the technology behind these machines, privacy concerns, and health impacts.

How Do Airport Body Scanners Work?

Airport body scanners are vital security tools used to detect potential threats and ensure the safety of passengers. These scanners work by using advanced technology to create images of the human body without the need for physical contact or the removal of clothing.

There are two main types of airport body scanners: millimeter wave scanners and backscatter X-ray scanners.

Millimeter Wave Scanners

Millimeter wave scanners use non-ionizing radiation to produce images of the body. This type of scanner emits low-energy radio waves that are harmless to humans. As a person passes through the scanner, the waves are reflected off the body and captured by sensors.

The sensors then create a three-dimensional image that can be analyzed by security personnel. Millimeter wave scanners are designed to detect both metallic and non-metallic objects on the body, including weapons and explosives.

These scanners are known for their ability to detect hidden objects, as they can penetrate clothing and reveal any concealed items. Additionally, millimeter wave scanners can detect abnormalities on the body’s surface, such as lumps or bumps, which may indicate the presence of inflammation or other medical conditions.

Backscatter X-ray Scanners

Backscatter X-ray scanners, on the other hand, use ionizing radiation to create images of the body. These scanners emit a small dose of X-rays that are scattered when they encounter the body. The scattered X-rays are then captured by detectors and transformed into an image.

Backscatter X-ray scanners are primarily used to detect objects concealed on the body, such as weapons or contraband.

It is important to note that backscatter X-ray scanners have been phased out in many airports due to privacy concerns and the potential health risks associated with ionizing radiation. However, they are still used in some airports where millimeter wave scanners are not available.

While airport scanners can detect metallic and non-metallic objects on the body, their ability to specifically detect inflammation is limited. These scanners are primarily designed for security purposes and may not be sensitive enough to identify inflammation or other medical conditions.

If a person has a medical condition that may be detected by an airport scanner, it is recommended to carry relevant medical documentation to avoid any misunderstanding or unnecessary delays during the security screening process.

What Can Airport Scanners Detect?

Airport scanners are designed to detect various items and substances that may pose a risk to the security of air travel. These scanners use advanced technology to identify and analyze different materials, allowing security personnel to identify potential threats quickly and efficiently.

Metallic and Non-Metallic Items

Airport scanners are primarily used to detect metallic items, such as weapons or other potentially dangerous objects. These scanners use X-ray technology to create detailed images of the items passengers are carrying.

Metallic objects, such as knives, guns, or even small metal components, can be easily detected by these scanners.

However, airport scanners are not limited to detecting only metallic items. They are also capable of detecting non-metallic items, such as explosives or illicit substances. Advanced scanners use a combination of X-rays and millimeter-wave technology to identify these substances, ensuring the safety of all passengers.

Medical Devices and Conditions

Airport scanners are designed to accommodate passengers with medical devices or conditions. These scanners are equipped with special settings that allow individuals with pacemakers, prosthetic limbs, or other medical implants to pass through without any issues.

The scanners are programmed to recognize and differentiate between medical devices and potential threats, ensuring that individuals with medical conditions can travel safely.

It’s important for individuals with medical conditions to inform airport security personnel about their condition and any medical devices they may have. This will help the security staff make the necessary accommodations and ensure a smooth and hassle-free screening process.

Do Airport Scanners Pose Health Risks?

Airport scanners have become a common sight in airports worldwide, used to ensure the safety of passengers and prevent any potential threats. However, concerns have been raised regarding the potential health risks associated with these scanners.

This article aims to explore the topic and provide an informed perspective on whether airport scanners pose any health risks.

Ionizing vs. Non-ionizing Radiation

One of the main concerns surrounding airport scanners is the type of radiation they emit. There are two types of radiation: ionizing and non-ionizing. Ionizing radiation, such as X-rays, has enough energy to remove tightly-bound electrons from atoms, which can potentially damage living tissues and DNA.

Non-ionizing radiation, on the other hand, has lower energy levels and does not have the same damaging effects.

Airport scanners use non-ionizing radiation, specifically millimeter-wave technology or backscatter X-rays. Millimeter-wave scanners emit radio waves that reflect off the body and create a detailed image, while backscatter X-rays use low energy X-rays to produce an image.

Both types of scanners are considered safe for use and have been extensively tested for potential health risks.

Studies on Safety

Extensive studies have been conducted to assess the safety of airport scanners. The Transportation Security Administration (TSA) in the United States, for example, has conducted numerous studies to evaluate the potential health risks associated with their scanners.

These studies have consistently found that the radiation emitted by airport scanners is well below the established safety limits and does not pose a significant health risk to passengers or operators.

In addition to government studies, independent research has also been conducted to evaluate the safety of airport scanners. One study published in the Journal of Radiation Research found that the radiation exposure from airport scanners is comparable to or even lower than other common sources of radiation, such as cell phones or Wi-Fi networks.

It is important to note that individuals with specific health conditions, such as pregnancy or certain medical implants, may have particular concerns about airport scanners. In such cases, it is advisable to consult with a healthcare professional for personalized advice.

Passenger Privacy Concerns

When it comes to airport security, passenger privacy concerns have always been a hot topic of debate. With the advent of advanced scanning technologies, such as full-body scanners, there has been a growing concern about the potential invasion of privacy.

Airport scanners are designed to detect various objects and substances that may pose a threat to aviation security, but what about the detection of personal medical conditions, like inflammation?

Understanding Airport Scanners

Airport scanners, including full-body scanners, use different technologies to create images of passengers’ bodies. These technologies include millimeter-wave scanners and backscatter X-ray scanners. While both types of scanners are effective in detecting concealed objects, they have different mechanisms and capabilities.

Millimeter-wave scanners use non-ionizing electromagnetic waves, which are harmless to humans, to create a detailed image of the body. These scanners can detect both metallic and non-metallic objects, but they are not designed to detect medical conditions such as inflammation.

On the other hand, backscatter X-ray scanners use low-energy X-rays to create an image of the body. These scanners can detect metallic objects as well as some organic materials, but they are primarily focused on identifying potential threats rather than medical conditions.

Privacy Measures in Place

While airport scanners are highly effective in detecting concealed objects and substances, passenger privacy remains a top priority for airport authorities. To address privacy concerns, various measures have been put in place:

  • Blur or distort the scanned image: The images produced by the scanners are often blurred or distorted to protect the privacy of passengers. The scanner operators cannot see the passenger’s face, and the images are not stored or shared.
  • Use automated target recognition software: Some scanners employ automated target recognition software, which analyzes the scanned images and automatically detects potential threats without revealing personal details.
  • Provide alternative screening options: Passengers who have concerns about the scanners can request alternative screening methods, such as a pat-down search, which is conducted in a private area by a same-gender officer.

The Limitations of Airport Scanners

While airport scanners play a crucial role in ensuring aviation security, it is important to note that they have limitations. They are not designed to diagnose medical conditions or detect inflammation.

The primary goal of airport scanners is to identify potential threats to aviation security and not to invade passengers’ privacy or reveal personal medical information.

It’s worth mentioning that the Transportation Security Administration (TSA), which oversees airport security in the United States, has implemented strict guidelines and protocols to protect passenger privacy.

These guidelines ensure that the use of airport scanners is in compliance with privacy laws and regulations.

The Future of Airport Screening Technology

Airport security has come a long way in recent years, thanks to advancements in technology. One area that has seen significant improvement is airport screening technology. Gone are the days of simple metal detectors and manual pat-downs.

Today, airports are equipped with state-of-the-art scanners that can detect a wide range of threats, from weapons to explosives. But what about detecting inflammation? Can airport scanners detect signs of inflammation in passengers?

An Overview of Airport Scanners

The two main types of airport scanners currently in use are millimeter-wave scanners and backscatter X-ray scanners.

Millimeter-wave scanners use radio waves to create an image of the body, while backscatter X-ray scanners use low-level X-rays. Both types of scanners have been extensively tested for safety and have been deemed safe for use on passengers.

They are designed to detect objects on or inside the body, such as weapons or explosives, but they are not specifically designed to detect inflammation.

The Limitations of Airport Scanners

While airport scanners are highly advanced, they do have their limitations. These scanners are primarily designed to detect threats, not medical conditions. Inflammation, which is often an internal condition, may not be easily detectable by airport scanners.

The scanners are more focused on identifying objects that pose a security risk, rather than identifying health-related issues.

It’s important to note that airport scanners are not a substitute for medical screening or diagnosis. If a passenger has a medical condition such as inflammation, it is best to consult a healthcare professional for proper evaluation and treatment.

While current airport scanners may not be able to detect inflammation, the future of airport screening technology looks promising. Researchers are constantly working on developing new technologies that can enhance airport security while also addressing health-related concerns.

One such technology is the use of thermal imaging cameras. These cameras can detect changes in body temperature, which could potentially be an indicator of inflammation or other health conditions. By integrating thermal imaging cameras into airport scanners, it may be possible to detect both security threats and health-related issues in the future.

Another area of research is the development of artificial intelligence (AI) algorithms. These algorithms can analyze the data collected by airport scanners and identify patterns that may indicate inflammation or other health conditions.

By leveraging the power of AI, airport scanners could become even more effective in detecting a wide range of threats, including health-related issues.


While millimeter wave and backscatter X-ray scanners at airports cannot diagnose medical conditions or inflammation, they serve an important purpose in detecting potential threats and contraband. Advancing screening technology aims to be even more effective at this security task while remaining mindful of passenger privacy and wellbeing.

So in summary – no, airport security scanners cannot detect inflammation or other health issues. They are designed to spot concealed items that could threaten passenger safety rather than diagnose medical conditions.
