- CT scanners, a type of x-ray machine used for luggage
- Walk-through metal detectors to detect metal objects
- Full-body millimeter wave scanners to reveal metal and non-metal objects
Is the airport body scanner an x-ray machine?
There are two types of airport body scanners: One type uses x-ray technology while the other uses millimetre-wave technology. In the US, Canada, and the European Union, airport scanners use millimetre-wave technology only. Millimeter-wave technology does not emit x-rays and does not pose any health risks.
What do airport body scanners see?

Airport body scanners in the US and Canada are able to detect metal and non-metal objects that may be concealed under clothing and their exact location on your body. Full-body scanners do not reveal your naked body or the insides of your body, instead, airport security staff see a generic human shape, without any specific identifying features, that resemble that of a doll. The generic human shape is the same for every traveler going through an airport scanner.
Can airport body scanners detect health issues?
Airport body scanners that use millimeter-wave technology, like those in the US and Canada, do not reveal what’s inside a person’s body. Unlike x-ray technology, millimeter-wave technology only checks the contour of the body; therefore, it cannot detect health issues such as tumors or inflammation.
Is it safe for pregnant people to go through an airport x-ray machine?
In the US and Canada, full-body scanners do not use x-ray technology, instead they use millimeter-wave technology, which is safe for pregnant people.

Can breast milk go through an airport scanner?
According to the TSA, the CT scanners and x-ray machines used to screen your luggage do not have any negative effects on food, medicine, or breast milk. However, If you prefer that the baby food you’re traveling with not go through the x-ray machine or CT scanner or be opened, you must inform the TSA agent. Note that in this case, you may be asked to go through additional security screening.
Traveling with breast milk can be daunting. Knowing what to expect when flying with breast milk can help you arrive prepared.
Can Dexcom go through airport security?
Dexcom is a continuous blood sugar monitoring system for people with diabetes. The system consists in a sensor attached to the body, often the belly or the back of the arm, that transmits glucose level to a portable device such as a cell phone or connected watch.
Dexom sensors should not go through full-body scans or x-ray machines, however, they can withstand metal detector and screening wands. Let the TSA agent know about your sensor prior to security screening, so they know to screen you with a pat-down, wand, or to perform a visual screening only. Make sure to explain that you cannot take off your sensor. Do not leave your Dexom sensor in your luggage or it will go through an x-ray machine; instead put it in a separate bag to give to the TSA agent.
The information above is valid for all CGM (continuous glucose monitoring) systems.

Can I go through an airport body scanner if I have a pacemaker?
Airport body scanners using millimeter-wave technology, like those in the US and Canada, are safe for people using pacemakers.
X-ray machines and metal detector pose very limited risk to those wearing a pacemaker, however, to be on the safe side, always inform the security agent that you have a pacemaker implanted.
Can I go through an airport body scanner if I have surgical metal implants?
It is safe for travelers with surgical metal implants like titanium hips, or plates and screws, to go through an airport body scanner.
Can I go through an airport body scanner if I have breast implants?
It is safe for travelers with breast implants to go through an airport body scanner. The breast implants will not be visible to the TSA agent.
Breast prosthesis, however, will be detected during a full-body scanner. Travelers with breast prosthesis should inform the TSA agent about their prothesis before proceeding into the scanner; they may go through additional security screening.
Can I go through an airport body scanner if I have a colostomy bag?
If you have an ostomy pouch, whether colostomy, ileostomy, and urostomy, inform the TSA agent before the security screening. You can go through the full-body scanner, the metal detector, or even a pat-down with your ostomy pouch, without having to empty it or show it to the TSA agent. Know that you may be required to undergo additional security screening.
How do you avoid body scanner at the airport?
In the US, travelers are allowed to refuse to go through the body scanner and opt for a physical search instead. Passengers who have been selected for enhanced screening, however, cannot opt out of the full-body scanner.
Travelers who sign up for TSA precheck can usually avoid having to through a full-body scanner, however, they still need to walk through a metal detector. 
Sure, I'm well-versed in airport security technology and its implications for travelers. The article touches upon several key technologies used in airport security:
1. CT Scanners: These machines utilize X-ray technology primarily for screening checked luggage. They provide detailed 3D images that allow security personnel to examine contents without physically opening bags.
2. Walk-Through Metal Detectors: These are familiar devices that use electromagnetic fields to detect metal objects on individuals passing through. They're designed to pick up metal items such as keys, coins, or other metallic objects.
3. Full-Body Millimeter Wave Scanners: These scanners use millimeter-wave technology to create an outline of the body and detect both metallic and non-metallic items concealed under clothing. Unlike X-rays, they don't reveal detailed anatomical structures but present a generic human shape.
Regarding the airport body scanners mentioned in the article:
Are Airport Body Scanners X-ray Machines? There are two types: one using X-ray technology and another utilizing millimeter-wave technology. In regions like the US, Canada, and the EU, millimeter-wave technology is predominantly used for security scans, which doesn't emit X-rays and is considered safe.
What Do Airport Body Scanners Detect? They identify concealed items, both metallic and non-metallic, under clothing. These scanners display a generic human shape without specific identifying features.
Can They Detect Health Issues? Millimeter-wave scanners, unlike X-ray technology, only assess body contours and cannot detect internal health issues like tumors or inflammation.
Safety for Pregnant Travelers: In the US and Canada, airport body scanners use millimeter-wave technology, deemed safe for pregnant individuals.
Handling Breast Milk and Medical Devices: CT scanners and X-ray machines used for luggage screening don't adversely affect breast milk or medical items. However, travelers can request alternative screening for sensitive items like breast milk or medical devices like continuous glucose monitoring systems (CGM) to avoid potential interference.
Pacemakers and Surgical Implants: Millimeter-wave scanners are generally safe for individuals with pacemakers or surgical metal implants.
Breast Implants and Colostomy Bags: Travelers with breast implants can safely go through body scanners, but those with breast prosthesis or colostomy bags should inform agents for additional screening.
Refusing Body Scanners: In the US, travelers can opt for physical searches instead of body scanners, except when selected for enhanced screening or for TSA PreCheck members who still pass through metal detectors.
Understanding the specifics of these airport security technologies can help travelers navigate screenings with confidence and ensure their safety and comfort while traveling.
