Airport X-Rays: Effective Security Or Privacy Invasion?

Airport X-ray machines are used to screen carry-on items and checked luggage, helping to keep travellers safe by identifying hidden weapons and other hazards. While they emit radiation, the risk of health effects is very low. However, some travellers may still be concerned about the potential dangers of X-ray screening, particularly as the technology becomes more advanced. For example, newer CT scanners use multiple radiation beams to create a 3D image of the scanned object, which could have a damaging effect on film.

X-ray scanners are used to identify hidden weapons and other hazards

Traditional X-ray scanners use a single beam of radiation to pass through an object and create an image on the other side. These are often much stronger and will ruin film. However, most current machines used for carry-on luggage scanning use a very mild dose of X-rays, which is safe for your film.

In contrast, CT scanners use multiple radiation beams to create a 3D image of the scanned object. CT scanners are more powerful and precise but emit a higher radiation dose. These are used for carry-on luggage, while checked-in luggage goes through traditional X-ray scanners.

The risk of health effects from backscatter X-ray systems and millimeter wave machines is very low. However, if you are worried about X-ray or millimeter wave screening, you are not required to walk through these machines. You can ask for a pat-down search instead.

The TSA uses x-ray machines to screen carry-on items and checked luggage. TSA x-ray equipment must meet the FDA requirements to limit passenger and worker exposure to radiation. TSA's occupational safety and health professionals adhere to specifications that meet the FDA requirements for screening equipment.

In contrast, CT scanners use multiple radiation beams to create a 3D image of the scanned object. CT scanners are more powerful and precise but emit a higher dose of radiation than traditional X-ray scanners. For example, a chest X-ray delivers 0.1 mSv, while a chest CT delivers 7 mSv, which is 70 times as much. The amount of radiation that patients are exposed to from CT scans varies widely between institutions and countries, and is largely due to differences in the technical settings of the scanning machines at each institution.

While CT scanners may seem like a step towards improved safety, they could have a very damaging effect on film. Most current machines used for carry-on luggage scanning use a very mild dose of X-rays, which is safe for film. However, more and more airports, usually the ones with higher traffic, are implementing CT scanner technology.
