X-Ray or X-Treme? The Truth About Airport Security Scanners

Standing in line at Malta International Airport, you’re about to step into the body scanner. You’ve heard the whispers – are these machines safe, or are they secretly zapping us with radiation? Let’s separate fact from fiction.

What’s the Buzz About?

Concerns about airport security scanners have been circulating for years. Some people worry about the health risks of low-dose radiation, while others fear that the machines infringe on their privacy. But are these fears founded, or are they just pre-flight jitters?

Malta’s Machines: The Lowdown

Malta’s airport uses two types of scanners – the millimeter wave scanner and the backscatter X-ray machine. Let’s take a closer look at each.

The millimeter wave scanner uses non-ionizing radiation, similar to that emitted by your microwave oven. It bounces harmless waves off your body to create a 3D image, helping security personnel detect any hidden objects. This type of scanner is used at the Departures Hall in Malta International Airport.

The backscatter X-ray machine, on the other hand, uses a low-dose of ionizing radiation to create an image. This type of scanner is less common and is not currently in use at Malta’s airport.

Radiation: Friend or Foe?

Let’s address the elephant in the room – radiation. The millimeter wave scanner uses non-ionizing radiation, which means it doesn’t have the same cancer-causing potential as ionizing radiation. In fact, the amount of radiation you’re exposed to in a millimeter wave scan is equivalent to about 10 minutes of natural background radiation.

As for the backscatter X-ray machine, the radiation dose is indeed higher, but it’s still extremely low. According to the Transportation Security Administration (TSA), the dose is equivalent to about two minutes of natural background radiation. To put that into perspective, a single transatlantic flight exposes you to more radiation than a backscatter scan.

Dr. Joseph Cuschieri, a Maltese radiation physicist, confirms these findings. “The radiation doses from airport scanners are negligible and pose no immediate or long-term health risks,” he says.

Privacy: The Other Concern

While the health risks of airport scanners are minimal, privacy concerns are more valid. The millimeter wave scanner creates a detailed 3D image of your body, which some people find intrusive. However, Malta’s airport uses automated target detection software, which means that the images are not viewed by a person. Instead, the software highlights any potential threats, and a security officer reviews these areas without seeing the full image.

As for the backscatter X-ray machine, it creates a less detailed image, but it’s still a concern for some people. Again, Malta’s airport does not currently use this type of scanner.

Opting Out: What Are Your Rights?

If you’re still uncomfortable with the idea of going through an airport scanner, you have the right to opt out. In Malta, you can request a pat-down search instead. However, be prepared for a longer security process, as a pat-down search takes more time than a scan.

Remember, the security officers at Malta’s airport are there to keep you safe. They’re trained to handle any situation professionally and respectfully.

So, are airport security scanners dangerous? The short answer is no. While they may cause some discomfort or privacy concerns, the health risks are negligible. The next time you’re at Malta International Airport, you can step into the body scanner with confidence, knowing that you’re helping to keep everyone safe.

“Airport security scanners are a vital tool in our fight against terrorism,” says Dr. Cuschieri. “They allow us to detect hidden threats quickly and efficiently, ensuring the safety of all passengers.”
