Airport body scanners are generally considered safe for pregnant individuals, utilizing non-ionizing technology that poses no known risk to the expectant mother or baby.
Traveling while expecting brings many considerations, and the safety of airport security procedures often comes up for discussion. It’s natural to prioritize the well-being of both yourself and your baby, especially when navigating the various technologies used at security checkpoints.
Understanding Airport Security Scanners
Modern airport security checkpoints primarily use two types of screening devices: walk-through metal detectors and advanced imaging technology (AIT) scanners. The AIT scanners are what many refer to as “body scanners.” These systems are designed to detect potential threats without physical contact, enhancing security measures.
The TSA states that all screening technologies used in airports are safe for all travelers, including pregnant women. The agency works closely with the Food and Drug Administration (FDA) and other health agencies to ensure the safety of these devices.
Millimeter Wave Scanners: The Primary Technology
The majority of advanced imaging technology (AIT) units deployed in airports are millimeter wave scanners. These devices emit low-power radio frequency (RF) waves, similar to those used in cell phones or Wi-Fi networks, but at significantly lower power levels. The waves reflect off the body, creating a generic outline image that security personnel review for anomalies.
Millimeter wave technology uses non-ionizing radiation. This means the energy emitted is not strong enough to remove electrons from atoms or molecules, which is the process that can cause DNA damage. The energy penetrates only a fraction of a millimeter into the skin and does not reach internal organs or the fetus. Medical and scientific communities agree that this type of radiation, at these power levels, does not pose a health risk to pregnant individuals or their developing babies.
Addressing Concerns About X-ray Scanners
A smaller number of older AIT units, known as backscatter scanners, used very low-dose X-rays. While these machines were also deemed safe by health organizations due to the extremely low dose of ionizing radiation (equivalent to a few minutes of natural background radiation), they have largely been phased out of US airports. The industry has moved towards millimeter wave technology as the standard for AIT screening.
Even when backscatter scanners were in use, the radiation exposure was minimal and localized to the skin surface. The dose was far below levels considered harmful to a fetus. Travelers today are highly unlikely to encounter a backscatter X-ray scanner in US airports.
Traditional Metal Detectors: A Safe Alternative
Walk-through metal detectors, often called magnetometers, operate using pulsed electromagnetic fields. These fields are also non-ionizing and do not emit radiation in the same way X-ray or millimeter wave scanners do. They work by detecting distortions in a magnetic field caused by metal objects.
Metal detectors have been used for decades and are widely accepted as safe for everyone, including pregnant women and individuals with pacemakers or other medical implants. There is no scientific evidence suggesting that the electromagnetic fields from these devices pose any risk to pregnancy.
| Technology Type | Energy Source | Pregnancy Safety |
|---|---|---|
| Millimeter Wave Scanner | Non-ionizing Radio Frequency (RF) waves | Generally considered safe |
| Traditional Metal Detector | Non-ionizing Electromagnetic fields | Generally considered safe |
| Backscatter X-ray Scanner | Very low-dose Ionizing Radiation (X-rays) | Considered safe, largely phased out |
Your Rights and Options at the Checkpoint
Every traveler has the right to request an alternative screening method. If you prefer not to go through an AIT body scanner or a metal detector, you can inform a TSA officer that you would like a pat-down instead. This is a standard procedure and is available to anyone.
When you request a pat-down, a TSA officer of the same gender will conduct the screening. You can request a private screening area, away from the main checkpoint, if you prefer. You may also ask for a witness of your choosing to be present, or a second TSA officer. While not required, some pregnant travelers choose to carry a doctor’s note, though TSA officers are trained to accommodate such requests without medical documentation.
Preparing for Your Trip: Beyond the Scanner
Beyond the security checkpoint, general travel health during pregnancy requires attention. Staying hydrated, moving frequently to prevent blood clots, and wearing comfortable clothing are important. For longer flights, compression stockings can be beneficial. It’s always a good practice to discuss any travel plans with your healthcare provider to ensure they align with your specific health needs and stage of pregnancy.
The CDC provides comprehensive travel health information, including guidance for pregnant travelers, covering vaccinations, food safety, and destination-specific health risks. Reviewing these recommendations can help you prepare for a safe and comfortable journey.
| Action Item | Details |
|---|---|
| Inform TSA Officer | Politely state you are pregnant and have questions or a preference for screening. |
| Request Pat-Down | You have the right to opt for a pat-down instead of a scanner. |
| Ask for Private Screening | If requesting a pat-down, you can ask for a private area. |
| Hydrate & Move | Stay hydrated before and after security; stretch when possible. |
Communicating with Security Personnel
Clear and polite communication with TSA officers can make your security experience smoother. Inform them of your pregnancy at the beginning of the screening process if you have specific requests or concerns. They are trained to handle a variety of situations and can explain the procedures and your options.
Remember that security personnel are focused on maintaining safety for all travelers. Approaching them with respect and clearly stating your preferences will help ensure a positive interaction and efficient screening process.
