Many pregnant women worry about the safety of exposing themselves and their unborn child to airport X-ray scanners. While it is not necessary to inform airport staff of your pregnancy, it can be helpful as they may offer you the option of a pat-down instead of going through the scanner. The level of radiation exposure from airport X-ray scanners is considered safe for everyone, including pregnant women, and is lower than the radiation from your phone. Modern millimeter body scanners do not use X-rays or expose your body to ionizing radiation. However, if you are still concerned, you can opt for a physical pat-down process, though this may take significantly longer.

What You'll Learn
Airport scanners are safe for pregnant women and their unborn children
It is understandable to be concerned about the safety of airport scanners during pregnancy. The good news is that, according to research, all types of airport scanners are safe for pregnant women and their unborn children.
Airport security systems use various technologies to ensure the safety of travellers, including metal detectors, backscatter X-ray machines, millimetre wave scanners, and cabinet X-ray machines. While some of these systems use ionizing radiation to scan luggage and identify hidden objects, the amount of radiation exposure is carefully monitored and regulated to ensure it is safe for all passengers, including pregnant women.
Modern millimetre body scanners, for example, do not use X-rays or expose individuals to ionizing radiation. Instead, they use low-energy radio waves, which are a form of electromagnetic energy similar to visible light but with much less energy. These scanners simply bounce waves off the surface of your skin to create a basic outline of your body, without penetrating inside. The level of radiation exposure from these scanners is lower than what you would receive from your phone.
Backscatter X-ray machines, which were previously used in some airports, have also been found to be safe for pregnant women. These machines use very low-dose X-rays that result in radiation exposure of less than 1 microsievert, which is far below the level required to harm a developing baby.
While airport scanners are generally considered safe for pregnant women, it is important to note that limited information is available regarding their impact during breastfeeding. If you have any concerns or feel uncomfortable about using a full-body scanner, you always have the option to request a physical 'pat-down' process as an alternative to the scanner.

Metal detectors may have more radiation than full-body scanners
Metal detectors and full-body scanners are used at airports to ensure the safety of passengers and staff. While both emit non-ionizing radiation, there are concerns that metal detectors may emit more radiation than full-body scanners.
Metal detectors use non-ionizing radiation to scan for small metal objects on a person's body. This type of radiation has enough energy to move atoms in a molecule or cause them to vibrate, but not enough to remove electrons from atoms. Metal detectors are designed to ignore very small amounts of metal, such as buttons or earrings.
Full-body scanners, on the other hand, use millimetre wave technology, which is a type of non-ionizing electromagnetic radiation similar to that used by wireless data transmitters. These scanners can detect both metallic and non-metallic objects, addressing security concerns that arose after airliner bombing attempts in the 2000s. They do not generate ionizing radiation and are considered safe for pregnant women and their unborn children. Reputed research firms have found that the radiation exposure from full-body scanners is well below stipulated limits and significantly lower than that from mobile phones.
However, an account from a pregnant traveller highlights a potential discrepancy in radiation exposure between metal detectors and full-body scanners. At one airport, the traveller was informed that the metal detector actually emitted more radiation than the full-body scanner, which used "just sound waves." In contrast, at JFK airport, the traveller was directed to use the metal detector, with no mention of an alternative option.
While the radiation exposure from airport security scanners is generally considered safe, some travellers may still have concerns, especially regarding the potential impact on pregnant women and their unborn children. To address these worries, airport security personnel can offer a pat-down screening as an alternative to passing through the scanners. This process may take longer, as it requires finding available staff, but it can provide peace of mind for travellers with anxieties about radiation exposure.

Pat-down searches are an alternative to X-ray scanners
While airport scanners are generally considered safe for pregnant women, you may still opt for a pat-down search as an alternative to X-ray scanners. This is always available to any passenger, including pregnant women, who are uncomfortable with passing through the scanners.
The level of radiation exposure from airport scanners is lower than what you receive from your phone. At these low levels, exposure is considered safe for everyone, including pregnant women and their babies. However, if you have concerns over the safety of the scanners or feel uncomfortable passing through them, you can ask the security professionals for a physical pat-down search.
During a pat-down search, a female security officer will run her hand along your entire body, especially your breasts and belly, to check for any prohibited items. You may be asked to loosen or remove some clothing, and the check takes much longer than stepping through a scanner.
It is important to note that the experience may vary depending on the airport. Some airports may be more accommodating than others in offering alternatives to X-ray scanners. Additionally, you may need to wait for someone to become available to perform the pat-down search, which can take a while if the airport is short-staffed.
Overall, while airport scanners are generally safe for pregnant women, the pat-down search option is available if you would prefer to avoid X-ray scanners during your pregnancy.

X-ray scanners deliver 10,000 times less energy than a cell phone
Passing through airport security scanners when pregnant is a concern for many women. However, there is well-researched evidence that airport security scanners are safe for pregnant women and their unborn children. The technology used in these scanners has been extensively tested and is deemed safe for all passengers.
The level of radiation exposure from airport scanners is extremely low. The two types of full-body scanners in use are millimeter-wave scanners and backscatter X-ray scanners. Millimeter-wave scanners emit extremely low-energy waves, delivering a small fraction of the energy of a cell phone. Backscatter X-ray scanners, the more common type in the US, utilize very low-dose X-rays, similar to those used in medical imaging. The radiation exposure from these scans is equivalent to 3-9 minutes of radiation received from naturally occurring sources or 1-3 minutes of flight time.
According to the American TSA, airport X-ray scanners deliver 10,000 times less energy than a cell phone. To put this into perspective, an individual would need to undergo 50 airport scans to equal the exposure of a single dental X-ray, 1,000 scans for a chest X-ray, 4,000 scans for a mammogram, and 200,000 scans to equal the exposure of a CT scan.
While the evidence suggests that airport scanners are safe for pregnant women, some women may still feel more comfortable opting for a physical "pat-down" process instead of going through the scanner. This alternative is available to any passenger who is uncomfortable with the scanners, and communicating pregnancy to security personnel can help ensure additional assistance during the screening process. However, it's important to note that a pat-down may take significantly longer, as it requires finding available staff to perform the search.

Backscatter X-ray machines are very low-risk
It is understandable to be concerned about the safety of airport X-ray machines, especially during pregnancy. The good news is that backscatter X-ray machines, which are used in airport security screening, pose a very low risk to individuals, including pregnant women and their unborn children. Here's why:
Firstly, backscatter X-ray machines use very low-energy X-rays that are reflected back to the machine itself. The amount of radiation from one backscatter scan is equivalent to the natural cosmic radiation you would experience during one to three minutes of flight time. The radiation exposure from these machines is also significantly lower than the radiation emitted by your mobile phone. In fact, reputed research firms and the American TSA state that airport X-ray scanners deliver up to 10,000 times less energy than a cell phone.
Secondly, backscatter X-ray technology does not penetrate the body and merely creates a basic outline of it. The machines detect the radiation that reflects off the target, forming an image. This means they do not emit radiation that can cause harm to a developing foetus or the mother. The technology is designed to detect items such as weapons, liquids, contraband, and other security threats, ensuring safe air travel without compromising the health of passengers.
Additionally, stringent safety measures and guidelines are in place to protect travellers and workers from excessive radiation exposure. The Transportation Security Administration (TSA) in the United States, for example, adheres to FDA requirements to limit passenger and worker exposure to radiation. The equipment is regularly tested and maintained to ensure it operates within safe parameters.
While some individuals may still have concerns or prefer not to use the backscatter X-ray machines, it is important to know that alternative screening methods, such as pat-down searches, are always available. These alternative methods ensure that pregnant women can choose the screening process they are most comfortable with while still maintaining the security standards necessary for air travel.
In summary, backscatter X-ray machines used in airport security screening are very low-risk for all passengers, including pregnant women. The machines operate with extremely low levels of radiation, and their use is carefully regulated to ensure the safety of travellers and staff. Alternative screening methods are also available for those who prefer them.
