Airport security scanners are a common concern for pregnant women, especially those who travel frequently. The scanners use different technologies, including radiofrequency, millimetre-wave imaging, and X-ray, to detect potential threats like weapons or explosives. While some expectant mothers worry about the potential effects of radiation exposure on their unborn children, it is important to know that airport security scanners are generally considered safe for pregnant women and their babies. The radiation exposure from these scanners is very low and does not penetrate the skin, posing no increased risk to the developing fetus. Additionally, regulatory bodies like the FDA ensure that all X-ray systems and radiation-emitting equipment are properly calibrated and maintained to further minimize any potential risks.

What You'll Learn
Radiofrequency scanners are safe for pregnant women
It is understandable to be concerned about the safety of airport scanners during pregnancy. The good news is that airport scanners are safe for pregnant women and their unborn children. Radiofrequency scanners, in particular, do not use ionizing radiation, so neither the mother nor the foetus is exposed to any hazardous radiation.
Radiofrequency scanners are one of the two main types of body scanners used in airports, the other being full-body x-ray scanners. Radiofrequency scanners use millimetre wave imaging technology to detect potentially dangerous objects that may be concealed under clothing. The scanner bounces waves off the body, which then go back to the machine for processing. This process only exposes individuals to very low levels of non-ionizing radiation, similar to the amount of radiation received from a mobile phone. At such low levels, exposure is considered safe for everyone, including pregnant women.
Full-body x-ray scanners, on the other hand, use very low-energy and low-intensity ionizing radiation. While this type of scanner does expose individuals to a small amount of radiation, it is not strong enough to penetrate the skin. Instead, it creates an outline of the external torso, with the internal organs receiving almost no radiation exposure. The amount of radiation received from a full-body x-ray scanner is comparable to the amount of cosmic radiation experienced during two minutes of flight.
It is important to note that the US Food and Drug Administration's (FDA) Center for Devices and Radiological Health (CDRH) ensures that all x-ray systems and other radiation-emitting screening equipment are designed to use radiation safely. The FDA requires that all machines be correctly calibrated and maintained to minimise any potential risks.
In conclusion, radiofrequency scanners and other airport security screening equipment are safe for pregnant women. The level of radiation exposure is extremely low and does not pose any increased risk to the unborn child. Pregnant travellers can feel reassured that passing through airport security will not harm their baby.

X-ray scanners are safe for pregnant women
It is understandable that pregnant women may be concerned about the safety of X-ray scanners at airport security checkpoints. However, it is important to know that these scanners are safe for pregnant women and their unborn children. The radiation emitted by these machines is very low and does not pose any health risks.
Firstly, it is crucial to understand that not all airport security scanners use X-rays. Some machines, such as metal detectors, utilise non-ionizing radiation, which is a safer alternative to detect any prohibited items without exposing individuals to ionizing radiation. This type of radiation is commonly used in other places like courthouses.
For the scanners that do use X-rays, the intensity and energy of the X-ray beams are kept very low and are specifically designed to create an outline of an individual's external torso. This means that the X-rays do not penetrate the skin, and as a result, an individual's internal organs, including those of a pregnant woman, are exposed to almost no radiation. Additionally, the amount of radiation emitted by these machines is significantly lower than what one would typically be exposed to during a medical X-ray.
The safety of X-ray systems and other radiation-emitting equipment is carefully regulated. The FDA's Center for Devices and Radiological Health (CDRH) ensures that all X-ray systems are built to use radiation safely and require all machines to be correctly calibrated and maintained. Furthermore, the radiation exposure from a single scan is about one-tenth of the exposure we receive daily from natural background radiation.
In conclusion, while it is natural to have concerns, X-ray scanners at airport security checkpoints are safe for pregnant women and do not pose any increased risk to their unborn children. These scanners emit very low levels of radiation that are carefully controlled and monitored to ensure the safety of all travellers, including those who are pregnant.

Metal detectors are safe for pregnant women
The amount of radiation emitted by metal detectors is also much lower than that of other airport security scanning equipment, such as backscatter x-ray machines. Backscatter machines use very low-energy x-rays that are reflected back to the machine itself. The amount of radiation received from a backscatter machine is equal to the amount of cosmic radiation received during two minutes of flight, and the risk of health effects is extremely low.
In addition, the FDA's Center for Devices and Radiological Health (CDRH) ensures that all x-ray systems and other radiation-emitting screening equipment are built to use radiation safely. The FDA requires that all machines be correctly calibrated and maintained. These rules apply to all x-ray equipment at airports, as well as medical equipment and other uses of radiation-emitting equipment.
Therefore, metal detectors are safe for pregnant women to pass through, and the radiation emitted is lower than that of other airport security scanning equipment, which is also safe for pregnant women.

Scanning wands are safe for pregnant women
It is understandable to be concerned about the safety of airport security scanners, especially during pregnancy. The good news is that airport scanning wands pose no risk to pregnant women or their unborn children.
Firstly, it's important to know that not all security scanners use ionizing radiation. Metal detectors, for example, use non-ionizing radiation, and the wands used for individual scanning emit no ionizing radiation, so you are not exposed to X-rays.
Even the full-body scanners, which use very low-energy and low-intensity X-rays, are considered safe for pregnant women. The energy of the X-ray beam is so low that it does not penetrate the skin, only creating an outline of your external torso. Your internal organs, therefore, receive almost no dose of radiation. The level of radiation you are exposed to during this process is lower than that from your phone or the natural background radiation you receive during two minutes of flight. At these low levels, exposure is considered safe for everyone, including pregnant women and their unborn children.
The FDA's Center for Devices and Radiological Health (CDRH) ensures that all X-ray systems and other radiation-emitting screening equipment are built to use radiation safely. They require all machines to be correctly calibrated and maintained, so you can rest assured that the equipment used at airports has been approved and is closely monitored.

Scanners emit low-level radiation
It is understandable to be concerned about the potential impact of airport scanners on your pregnancy. Scanners emit low-level radiation, but this does not pose a risk to you or your unborn child. The radiation exposure from these scanners is minimal and considered safe for all travellers, including pregnant women.
Firstly, it is important to understand that radiation is present in our everyday lives, and the amount of radiation we are exposed to during a security scan is significantly lower than what we experience daily from natural background radiation. The manufacturers of these scanners indicate that the radiation exposure from one scan is about one-tenth of the exposure we receive daily from natural sources.
Secondly, the type of radiation used in airport scanners is crucial to consider. Airport security systems may use different types of radiation, including ionizing and non-ionizing radiation. Ionizing radiation, such as X-rays, can be found in medical imaging equipment and some airport screening devices like backscatter X-ray machines and cabinet X-ray systems. However, these machines operate at very low energy and intensity levels, ensuring that the radiation exposure to passengers is extremely low. The X-ray beams used in backscatter machines, for example, do not penetrate the skin and only create an outline of a person's external torso. As a result, internal organs, including those of a developing embryo, receive almost no radiation dose.
Additionally, it is worth noting that not all airport scanners use ionizing radiation. Some devices, such as metal detectors and radiofrequency scanners, utilise non-ionizing radiation, which does not pose any health risks related to radiation exposure. These scanners operate at frequencies that do not cause harm to the human body, even at higher exposure levels.
The safety of these scanners has been extensively evaluated by organisations such as the FDA's Center for Devices and Radiological Health (CDRH) and the Health Physics Society (HPS). The CDRH ensures that all X-ray systems and radiation-emitting screening equipment are designed to use radiation safely and require strict calibration and maintenance standards. The HPS, an independent scientific organisation, also provides information and recommendations to help the public better understand radiation and its effects.
