Does IUD set off a metal detector at the airport?
My wife and I often fly to various destinations across the world and one question that has recently got us thinking is “does an IUD device set off a metal detector during the screening process?”
This is after one of our friends decided to adopt IUD as her birth control method.
Intrauterine Devices are fast becoming a favorite among females seeking birth control services.
According to statistics in the USA, contraceptive users aged 25-29 had the highest IUD use rates (19%) compared to others.
Implant use was highest in the youngest age group (15-19), at 16%, and declined with each successive age group, reaching less than 2% among individuals aged 30-49.
So, if you’re wondering whether this device can be detected by a metal detector, then you’re at the right place.
In this post, I will answer comprehensively the question “does IUD set off a metal detector at the airport?”
Does IUD Set Off a Metal Detector at the Airport?
The answer is NO. Copper coil IUDs won’t set off airport security metal detectors.
They’re small, lightweight, and located deep enough inside your body for a metal detector to be unable to pick them up.
However, there have been instances where individuals with an IUD have had the metal detector indicate something in their lower back area.
This could be due to other factors such as clothing or body shape.
If your implanted device sets off the metal detector alarm, you’ll likely be asked to proceed with a secondary screening.
Does IUD Set Off a Metal Detector at the Airport? Understanding IUDs
Definition and Purpose of Intrauterine Devices (IUDs)
An intrauterine device (IUD) is a small, T-shaped device that a healthcare provider inserts into your uterus for long-term birth control.
They are the most commonly used type of long-acting reversible contraception (LARC).
Once an IUD is inserted, it can prevent pregnancy for up to 10 years or more, depending on the specific type.
Your healthcare provider can remove your IUD at any time if you decide to become pregnant.
Common Materials Used in IUDs
There are two types of IUDs namely copper IUDs and hormonal (levonorgestrel) IUDs.
Both have plastic frames that open into the shape of a T once inside your uterus.
They have strings attached at the bottom that extend into your vagina so that your provider can remove your IUD as needed.
Copper IUDs have a thin copper wire that coils around the stem part of the “T”.
Hormonal (levonorgestrel) IUDs contain the progestin hormone levonorgestrel, which flows through the stem.
How Do IUDs Function?
The two different types of IUDs work differently.
The one that is covered with copper releases copper ions. These ions prevent the sperm from moving and therefore reaching the egg.
The hormone-releasing IUDs are coated with the hormone levonorgestrel, a type of progestin.
This thins your uterine lining while, at the same time, thickening your cervical mucus, making it extremely difficult for sperm to reach your eggs.
Airport Security and Metal Detectors
A Brief Explanation of Airport Security Procedures
Airport security procedures are designed to ensure the safety of all passengers and are a mandatory part of flying.
Here’s a brief explanation of some common procedures:
Full-Body Scanners: These scanners are used to detect threatening items and contraband such as weapons, explosives, and drugs under multiple layers of clothing.
You’ll stand inside a large plastic tube with your hands in the air while the scanner operates.
Hand Luggage Liquid Restrictions: All liquid items need to be in containers 100ml or less when in carry-on luggage.
These items must be extracted from your luggage for the scanning process, and in some cases placed in a clear plastic zip-lock bag.
Trace Detection with Swabbing: This is another method used to detect explosives or narcotics.
A small piece of fabric is swiped over your hands, clothing, and luggage, then analyzed for traces of these substances.
Biometric Identification: Some airports use biometric identification methods, such as facial recognition or fingerprint scanning, as part of their security procedures.
Detection Dogs or ‘Sniffer Dogs’: These trained dogs are used to detect drugs, money, explosives, and agricultural products
Ticket and ID Verification: Once you’ve reached the front of the security queue, an officer will ask you to come to a podium.
Have airline tickets ready, and anyone 18 or older will need some kind of identification document ready – a passport will work in any case.
Remember that security measures can vary between airports and countries, and it’s always best to check the specific requirements of the airport you’ll be traveling through.
Role of Metal Detectors in Airport Security
Metal detectors play a critical role in airport security.
They are used to detect weapons and other dangerous items, creating a barrier that prevents such contraband from entering the airport.
Here’s how they work:
Pulse Induction Technology: Almost all airport metal detectors are based on pulse induction (PI) technology.
These detectors send powerful, short bursts (pulses) of current through a coil of wire, generating a brief magnetic field.
When a metal object passes through the detector, the pulse creates an opposite magnetic field in the object, causing the reflected pulse to take longer to decay.
This change is detected by the sampling circuit in the metal detector.
Detection and Alarm: The sampling circuit sends the tiny, weak signals that it monitors to a device called an integrator.
The integrator reads the signals from the sampling circuit, amplifying and converting them to direct current (DC).
The DC’s voltage is connected to an audio circuit, where it is changed into a tone that the metal detector uses to indicate that a target object has been found.
Secondary Screening: If an item is found, you are asked to remove any metal objects from your person and step through again.
If the metal detector continues to indicate the presence of metal, the attendant uses a handheld detector, based on the same PI technology, to isolate the cause.
In addition to their primary function of detecting metallic objects, metal detectors also act as a deterrent, as potential attackers know their weapons will be detected.
Types of Materials and Objects that Trigger Metal Detectors
At airports, metal detectors are primarily used to detect metallic objects that could pose a security threat.
Here are some typical materials and objects that can trigger metal detectors at the airport:
Personal Items: Common personal items like keys, coins, belt buckles, watches, and jewelry can trigger metal detectors.
These items are typically placed in a tray for separate scanning.
Electronic Devices: Electronic devices such as laptops, tablets, cameras, and cell phones contain metal components and batteries that can set off metal detectors.
These items are also usually placed in a separate tray for scanning.
Clothing Accessories: Certain clothing accessories like underwire bras, metal zippers, and shoe shanks can sometimes trigger metal detectors.
Medical Devices: Some medical devices like pacemakers, artificial joints, and metallic implants can potentially set off metal detectors.
Travelers with these devices are usually advised to inform security personnel beforehand to avoid any inconvenience.
Carry-on Items: Items in carry-on luggage such as pocket knives, vapes, scissors, and tools can trigger metal detectors.
These items are generally prohibited in carry-on luggage and should be packed in checked luggage instead.
Certain Foods: Some foods that are packed in foil or have a high metal content can potentially trigger metal detectors.
Can Airport Metal Detectors Detect an IUD? The Metal Content of IUDs
The Metal Content in Different Types of IUDs
There are two main types of IUDs: copper IUDs and hormonal IUDs.
Copper IUDs, as the name suggests, contain a small amount of copper, which is wrapped around the plastic frame.
Hormonal IUDs, on the other hand, are primarily made of plastic and contain a hormone called levonorgestrel.
Examination of Whether IUDs Contain Enough Metal to Trigger a Metal Detector
The amount of metal in an IUD is quite small.
In the case of copper IUDs, the copper is wrapped around a plastic frame, so the overall metal content is minimal.
Hormonal IUDs contain even less metal, as they are primarily composed of plastic.
Therefore, it’s highly unlikely that an IUD would contain enough metal to trigger a metal detector.
Factors Influencing the Likelihood of Detection
Several factors can influence whether an IUD is detected by a metal detector.
These include the sensitivity of the detector, the type and amount of metal in the IUD, sensitivity levels of the detector and its location in the body.
However, given the small amount of metal in IUDs and their location deep within the body, it’s highly unlikely that an IUD would be detected by a standard airport metal detector.
What is TSA’s Stance on IUDs?
The Transportation Security Administration (TSA) does not specifically mention IUDs in their security procedures.
However, they do state that all travelers are required to undergo screening at the checkpoint.
If a traveler has a medical condition or device, they can consult with the TSA officer about the best way to relieve any concerns during the screening process.
Travelers may provide the officer with a TSA notification card or other medical documentation to describe their condition.
In an anecdotal case, a traveler joked that her IUD might be setting off the metal detector, which led to some confusion with the TSA agent who was not familiar with what an IUD is.
This suggests that while IUDs are not commonly recognized by TSA agents, they do not typically cause issues during security screenings.
If you’re traveling with an IUD and are concerned about it causing issues during security screenings, it may be helpful to inform the TSA officer beforehand.
However, given the small amount of metal in IUDs and their location deep within the body, it’s highly unlikely that an IUD would be detected by a standard airport metal detector.
Opinions and Research on the Question “Does IUD Set Off a Metal Detector at the Airport?”
While there isn’t a lot of research or expert opinion specifically on the question of whether an IUD can set off a metal detector at the airport, anecdotal evidence suggests that it’s highly unlikely.
In a discussion on Reddit, a user shared their experience of traveling with an IUD.
They mentioned that they went through the metal detector twice and both times, the detector indicated something in their lower back area.
They assumed it was their copper IUD (Paragard).
However, another user clarified that the machine used at airports is not actually a metal detector but more like a density detector.
The wavelength it uses to determine density can’t penetrate more than a millimeter into your skin, so it’s not physically possible for it to detect an IUD.
This aligns with what we know about the composition of IUDs and how metal detectors work.
IUDs contain a very small amount of metal (copper in the case of copper IUDs), and they are located deep within the body.
Metal detectors, on the other hand, are designed to detect larger amounts of metal closer to the surface.
So, while it’s theoretically possible for an IUD to set off a metal detector if the detector is sensitive enough, it’s highly unlikely in practice.
If you’re traveling with an IUD and are concerned about it causing issues during security screenings, it may be helpful to inform the TSA officer beforehand.
Mitigating Concerns
Tips for Travelers with IUDs to Minimize Potential Issues at Airport Security
Inform the TSA officer: If your IUD is visible to TSA, you should inform the officer of its presence.
You may provide the officer with a TSA notification card or other medical documentation to describe your condition in a discrete manner.
Consult a TSA officer: Passengers with a disability or medical condition or their traveling companion may consult a TSA officer about the best way to relieve any concerns during the screening process.
Advice for Addressing Security Concerns with TSA or Airport Staff
Be courteous and polite: Smile, and say ‘thank you.’ Being overly talkative may be a red flag.
Use TSA resources: TSA has five main resources for travelers with disabilities or individuals who travel with medical devices or medical conditions to ensure that they can get through the security screening process successfully, respectfully and efficiently.
They include the TSA Cares helpline, the TSA Contact Center, Passenger Support Specialists, information posted on the TSA website and an interactive Twitter and Facebook Messenger account.
Alternative Screening Options
TSA PreCheck: Provides expedited, less intrusive screening at domestic airports in the United States.
Global Entry: Allows expedited entry via air, land and sea into the United States and includes TSA PreCheck.
NEXUS: Provides expedited entry into Canada via air, land and sea, while also offering full TSA PreCheck and Global Entry benefits.
CLEAR Plus: Provides rapid identity verification and a shortcut through airport security.
Remember, these programs require an application process and may have associated fees.
It’s important to choose the one that best fits your travel style and needs.
Rights of Individuals with IUDs During Security Checks
Individuals with IUDs have the same rights as other passengers during security checks.
They are entitled to be treated with dignity and respect.
If an IUD is visible to TSA, passengers should inform the officer of its presence.
They may provide the officer with a TSA notification card or other medical documentation to describe their condition in a discrete manner.
It’s important to note that passengers have the right to request a private screening at any time and can also have a companion, assistant, or family member present during the screening process.
If at any time during the screening process you feel your rights are being violated, you have the right to ask for a supervisor or manager.
Does IUD Set Off a Metal Detector at the Airport? Final Thoughts
Does IUD set off a metal detector at the airport? The answer is NO.
IUD devices have very small amounts of metal that cannot set off a metal detector during the screening process.
Intrauterine devices (IUDs) are typically made of plastic and copper or hormones.
They are not large enough or composed of enough metal to set off a metal detector.
However, if your IUD is visible to TSA, you should inform the officer of its presence.
It’s important to stay informed about current airport security procedures and to communicate openly with TSA officers about any concerns you may have.
Frequently Asked Questions
Is There Metal in an IUD?
YES, there is metal in some types of IUDs.
Specifically, copper IUDs, such as Paragard, are wrapped in a tiny bit of copper.
Copper is a spermicide, something that kills sperm, which helps prevent pregnancy.
However, it’s important to note that not all IUDs contain metal.
Some IUDs, like Mirena, Kyleena, Liletta, and Skyla, use the hormone progestin to prevent pregnancy.
Does an IUD Need to be Checked?
Intrauterine devices (IUDs) are typically made of plastic and copper or hormones.
They are not large enough or composed of enough metal to set off a metal detector.
However, if your IUD is visible to TSA, you should inform the officer of its presence.
You may provide the officer with a TSA notification card or other medical documentation to describe your condition in a discrete manner.
If you choose not to be screened through the Advanced Imaging Technology (AIT), or a walk-through metal detector (WTMD), you will undergo a pat-down screening.
Can Period Blood Set Off Metal Detectors?
Period blood itself does not set off metal detectors.
However, some period products can be detected by body scanners at airport security checkpoints.
The scanners can flag these products as potential threats, triggering additional searches.
This is not due to the presence of metal, but rather the way these products can appear on the scanner.
It’s important to note that this doesn’t happen all the time and varies based on the type of scanner and the specific product being used.
Will a Bra Set Off a Metal Detector?
YES, underwire bras can sometimes set off metal detectors or show up on other airport security scans.
However, most bras are made of lightweight fabrics that do not contain enough metal to trigger the alarms.
Even if you don’t wear an underwire bra, the metal hooks or clasps in bras or on regular garments can make a detector go beep!
TSA rules do not mention underwire bras specifically so they can certainly be worn through the security checkpoint.
There is a very small possibility that they may trigger an alarm at the metal detector.
In general, most women’s experience of wearing an underwire bra through airport metal detectors at the security checkpoint is that they will not set off the alarm.
If you happen to set off an alarm, and you believe it can only be due to you having wire in your bra, then tell a female security officer.
She will probably use a handheld metal detector wand initially to see where you set off the metal detector.
She may then want to do a manual “frisk” and you would be well within our rights to ask for this to be carried out in a private area.
Can Airport Scanners See Breast Implants?
YES, airport scanners can see breast implants.
Full-body scanners show numerous kinds of implanted medical devices, ranging from pacemakers to artificial joints, and breast implants are no exception.
However, it’s important to remember that the security officers at airports are professionals and aren’t looking to humiliate you; they’re looking for objects that could compromise safety.
Also keep in mind that you are not required to tell anyone that you have breast implants.
If you choose the pat down vs. the scanner, you do not need to tell screeners you have implants when they ask if you have any internal implants.
Can Airport Scanners Detect Pills?
YES, airport scanners can detect pills.
This is regardless if the pills are contained in plastic pill bottles, or contained in any other non-metallic and metallic objects.
However, a passenger has the right to refuse to have any pills or other medication they are traveling with X-rayed, and can instead opt for a visual inspection instead.
It’s important to note that the TSA does not require passengers to present their medication or even notify an officer about any medication they are flying with.
However, if you are traveling with liquid pills, these are subject to additional screening.
At the start of the screening checkpoint process, you should inform the officer that you are traveling with medically required liquids.
As long as the pills are screened, you are able to bring an unlimited amount with you.
As long as not in liquid form, there is no limit to the number of pills you can fly with.
The exception to this is pills in liquid form.
If you intend to travel with liquid pills in your carry-on baggage, they must not exceed 3.4 ounces/100ml.
