Airport body scanners use non-ionizing radiation, which is lower energy than ionizing radiation. This means that the radiation does not have enough energy to damage the cells of pregnant women or their babies. The two types of airport scanners are millimeter-wave scanners and x-ray backscatter scanners, and both are considered safe for pregnant women and their babies. The scanners do not produce a body image, so they cannot see the baby. However, pregnant women who are concerned about the safety of scanners can request a physical pat-down search instead.

Airport scanners are safe for pregnant women and their babies
Many pregnant women worry about the potential risks of airport scanners and how safe they are for their unborn babies. However, there is well-researched evidence that airport security scanners are safe for both mother and baby.
Airport scanners are advanced screening gadgets that detect any security threats attached to the body and/or garments of airline passengers. They come in many forms, including body scanners, walk-through metal detectors, and hand-held scanning wands. The two basic types of body scanners are millimeter-wave scanners and x-ray backscatter scanners. Both types of scanners are safe to use on pregnant women and children.
Millimeter-wave scanners use millimeter-wave Advanced Imaging Technology (AIT) to create 3-D images of the body. These waves reflect away from the skin surface and cannot penetrate the skin. They can cause no harm to the mother or her unborn baby.
Backscatter scanners use low-frequency electromagnetic x-ray waves to search for objects hidden inside a person’s clothing. The low-intensity and low penetration level of the electromagnetic wave cause minimum exposure to rays. Hence, it can cause no harm to a baby developing in the womb. The scanner merely probes through the passengers’ garments and not the skin. According to the American TSA, these scanners deliver 10,000 times less energy than your cell phone.
Metal detectors are another type of screening technology that is safe for pregnant women. These old-fashioned screeners use non-ionizing radiation, which is very low-frequency. They merely detect any threatening objects being carried and do not pose a risk to pregnant women and their babies.
If you are concerned about the safety of airport scanners during pregnancy, you can opt for a physical 'pat-down' search instead.

Scanners use low-intensity rays that cannot penetrate the skin
Airport scanners use advanced imaging technology to detect potential threats hidden within a person's body or clothing. They can detect metallic and non-metallic items, including knives, explosives, and weapons. There are different types of scanners used at airports, including metal detectors, backscatter X-ray machines, millimeter wave scanners, and cabinet X-ray machines.
Millimeter wave scanners, one of the most commonly used airport scanners, emit non-ionizing radiofrequency waves. These waves are reflected off the body and bounce back an image to the machine, which is then interpreted by the software. Importantly, these waves do not penetrate the skin and only reflect off the skin surface. The machines emit far less energy than a cell phone, and the radiation exposure is well within permissible limits.
Backscatter X-ray machines, another type of airport scanner, use very low-energy X-rays that are reflected back to the machine. The amount of radiation received from these machines is equivalent to the cosmic radiation experienced during two minutes of flight, and the risk of health effects is extremely low. Additionally, these machines have safety features such as thick walls and lead curtains to prevent radiation leakage.
While airport scanners can detect items on or inside a person's body, they do not produce detailed body images. Instead, they provide a generic avatar or outline of the human anatomy to maintain privacy. Furthermore, these scanners do not penetrate the skin, so they cannot detect items hidden inside body cavities.
In summary, airport scanners use low-intensity rays that cannot penetrate the skin. They are designed to detect potential threats while ensuring passenger privacy and safety. The radiation exposure from these scanners is carefully regulated and monitored to meet health and safety standards. As such, they are considered safe for pregnant women and their unborn babies.

Millimeter-wave scanners reflect off the skin and cannot cause harm
It is understandable to be concerned about the safety of airport scanners, especially for pregnant women and their unborn babies. However, millimeter-wave scanners, a common technology used in full-body scanners, are considered safe and cannot harm you or your unborn child.
Millimeter-wave scanners work by directing millimeter wave energy at the subject and then interpreting the reflected energy to create an image. These waves reflect off the skin and do not penetrate it. The waves produced by these scanners are much larger than X-rays and are non-ionizing, meaning they do not have enough energy to alter the structure of biological molecules or cause cancer. The radiation used in these scanners is non-ionizing electromagnetic radiation, which is not known to cause any adverse health effects. While the exact effects of airport scanners on pregnancy have not been extensively studied, the current evidence suggests that the low-intensity rays used in these scanners are safe for both the mother and the unborn baby.
The use of millimeter-wave scanners in airports is regulated and set at a maximum permissible exposure level for the public, including pregnant women and children, by the Radiation Protection Standard. This standard ensures that the scanners do not emit harmful levels of radiation. Additionally, millimeter-wave technology has been further developed to enhance security and improve the traveler experience. For example, PNNL has created a Millimeter-Wave Shoe Scanner that can detect concealed objects in footwear without requiring passengers to remove their shoes, streamlining the security process.
While millimeter-wave scanners are generally safe, some people may still have concerns or feel uncomfortable passing through them. In such cases, individuals can opt for a physical 'pat-down' search or a thorough hand search in a private room. These alternative methods ensure that security checks can be conducted without the use of scanners, addressing any worries or discomfort related to their use.
In summary, millimeter-wave scanners reflect off the skin and are designed to be safe for all passengers, including pregnant women and their unborn babies. The non-ionizing radiation used in these scanners does not penetrate the skin and has not been shown to cause any adverse health effects. With safety measures in place and advancements in technology, millimeter-wave scanners are a reliable and harmless method for ensuring the security of travelers and their belongings.

X-ray backscatter scanners are also safe for pregnant women and their babies
Many pregnant women worry about the potential health risks of airport security scanners for their babies. However, sources suggest that X-ray backscatter scanners are safe for pregnant women and their babies.
Firstly, X-ray backscatter scanners emit low-intensity radiation that does not penetrate the skin or harm the fetus. The low-frequency electromagnetic waves used by these scanners cannot pass through the skin, only clothing. This means that the scanners cannot produce a body image, so they cannot see the baby.
Secondly, the amount of radiation exposure from backscatter scanners is not high enough to pose a threat to human health. According to the Centers for Disease Control and Prevention (CDC), nonionizing radiation does not pose a risk to pregnant women and their babies. This is because it is lower energy than ionizing radiation and does not reach far inside the body. A 2011 study in the Archives of Internal Medicine also found that the risk of cancer from radiation exposure with backscatter scanners was "truly trivial".
In addition, the Radiation Protection Standard sets a maximum permissible exposure level for the public, including pregnant women and children. The amount of radiation received from a backscatter scanner is equal to the amount of cosmic radiation received during two minutes of flight.
Despite this, some sources advise pregnant women to avoid X-ray machines at airport security. If you are concerned about the safety of X-ray backscatter scanners, you can request a physical 'pat-down' search instead.

If concerned, request a physical 'pat-down' search instead
While airport scanners are deemed safe for pregnant women and their babies, you may still have concerns about the safety of these scanners or feel uncomfortable passing through them. If so, you can opt for a physical 'pat-down' search instead. This is a thorough hand search usually performed in a private room, where security staff may ask you to loosen or remove some clothing. This process is lengthier than passing through a scanner, but it ensures your baby is not exposed to any form of radiation, no matter how minimal.
According to the American TSA, airport scanners deliver 10,000 times less energy than your cell phone, and the radiation exposure is well below the limits stipulated by the Radiation Protection Standard. This standard sets a maximum permissible exposure level for the public, including pregnant mothers and children. The scanners emit low-intensity radiation that does not penetrate the skin or harm the fetus.
Despite these assurances, if you are worried about the potential risks of airport scanners, you can always request a pat-down search. This option is available to all travellers, and you are within your rights to make this request. The alternative physical search will be conducted by a female Transportation Security Officer to ensure your comfort and privacy.
It is important to remember that airport scanners are advanced screening tools that have been extensively tested and deemed safe for all passengers, including pregnant women and their babies. The scanners use low-frequency electromagnetic waves to detect objects hidden inside a person's clothing, and these waves do not penetrate the skin. However, if you would prefer to avoid any potential exposure, requesting a pat-down search is a reasonable and valid option.
In addition to the pat-down search, you can also opt for the old-fashioned metal detectors that are still used in many airports. These metal detectors use magnetic fields that are a form of "non-ionizing" radiation, which is very low-frequency and safe for pregnant women and their babies.
