Many of us have experienced the frustration of airport security lines. One of the often-dreaded processes is passing through the scanners. These machines promise to make the process easier, safer, and less invasive than pat-downs or frisking.

However, there are concerns that these machines might pose hidden health risks that may not be well understood by the public.

The Two Types of Airport Scanners

There are two types of airport scanners: millimeter-wave scanners and backscatter X-ray scanners.

What are Millimeter-Wave Scanners?

Millimeter-wave scanners emit millimeter waves, which are non-ionizing radio-frequency waves, to create an image of your body using reflected energy.

They can be seen as less invasive and less harmful than backscatter X-ray scanners that emit ionizing radiation.

What are Backscatter X-ray Scanners?

Backscatter X-ray scanners use low levels of ionizing radiation in the form of X-rays to penetrate your body. The radiation is then absorbed in varying amounts by different body tissues, creating an image for airport personnel to review.

Because of this, backscatter X-ray scanners carry the potential health risks associated with ionizing radiation exposure.

The Health Risks of Backscatter X-ray Scanners

The primary health risk posed by backscatter X-ray scanners is exposure to ionizing radiation.

Although the amount of exposure from one scan is very small – roughly equivalent to the radiation exposure during a two to three minute flight – frequent exposures can cumulatively increase the risk of developing cancer or genetic mutations. This is especially a concern for individuals who are frequently tested or those who work in airports and are exposed on a regular basis.

In addition, certain individuals may be more susceptible to radiation exposure than others. Pregnant women, young children, and individuals with weakened immune systems may be at higher risk of health problems as a result of exposure to radiation.

Steps Taken for Safe Use of Airport Scanners

Despite concerns, airport scanners have been deemed safe for use by multiple sources. The U.S.

Food and Drug Administration (FDA), the American College of Radiology, and the National Council on Radiation Protection and Measurements have all concluded that airport scanners do not pose a significant risk to public health and safety when used properly.

However, to ensure safe use of airport scanners, there are several measures that have been put in place. These include regular calibration and maintenance of the machines, proper security officer training, and adherence to safety guidelines.

Alternatives to Airport Scanners

For those who are worried about the potential health risks associated with airport scanners, alternative screening methods exist.

One of the alternatives is undergoing a pat-down instead of going through a scanner. This involves a TSA agent searching your body with their hands, but it can be more invasive than going through the scanner.

Another alternative is using TSA PreCheck, which allows eligible passengers to go through a shorter security line that does not require them to pass through a scanner.

TSA PreCheck is designed to expedite the screening process while maintaining a high level of security.

The Bottom Line

Despite the reassurances of safety from health organizations, the potential risks associated with airport scanners cannot be ignored.

It is essential to weigh the convenience of going through the scanner against the potential health risks associated with frequent exposure to ionizing radiation. If you have concerns about the risks, it’s also essential to explore alternative screening options, such as a pat-down or TSA PreCheck.
