Do you know that an airport security priority is to guarantee passengers’ and workers’ safety? So, the airport uses scanners like deep search metal detectors to detect things that might harm people’s lives, such as knives, guns, and explosives.
Since many things pass via the airport, the scanners must be powerful to assist the security personnel in identifying illegal items. Generally, metal detectors can’t detect non-metallic things. However, an advanced airport scanner using RTVS technology can detect non-metallic and metallic objects. This means security personnel can detect potentially dangerous items.
Here is all you need to know about airport scanners.
Types of Airport Scanners
The primary operating principle of airport scanners like deep search metal detectors is utilising higher energy electromagnetic radiation known as X-ray radiation. The X-rays are blocked or dimmed by every substance or material to a certain degree, and comparisons are made between the levels to which objects block them.
There are many types of airport scanners. At the airport, you’ll identify at least two types of these scanners at the security checkpoints, one for your body and the other for luggage bags. The scanner’s purpose is to detect those items that metal detectors can’t detect. Since they’re known to be the critical line of defence against terror attacks, they feature advanced technology.
To know how they work, you need to understand each type of scanner in detail. The two types include full body and airport baggage scanners.
Full Body Scanners
A full body scanner scans the entire body of the traveller at the airport security screening. There are two full-body scanners in this category: the backscatter X-ray and the millimetre wave scanner.
– Backscatter X-ray scanner
These scanners can scan and detect any illegal substances. Nevertheless, their flaw is that it takes a long to complete the scan and produce the image. For that reason, most airport security processes use millimetre wave scanners instead.
– Millimetre-wave scanners
These use millimetre waves to scan the body and other objects. These are electromagnetic waves in the frequency range of 30 to 300 GHz. The waves bounce off the item and generate an animated image that is coloured depending on the potential threat levels to identify the points of interest that could require additional scrutiny.
Airport Baggage Scanners
These scanners scan carry-on luggage and checked luggage. They work the same as the backscatter X-ray scanners, but they utilise X-rays that look into the bag and monitor the contents of the luggage. The scanners focus on the edges of the items, letting the security officers see through the bag content and detect any illegal items easily.
Can airport scanners detect drugs?
Airport scanners alone cannot outrightly detect drugs. They simply produce a detailed image of a passenger’s belongings, and if there is something suspicious, security personnel can investigate further. to detect drugs and other illegal substances, additional security measures such as sniffer dogs are used.
The advanced imaging technology in most airport scanners produces X-ray images that security officers can discern whether the traveller poses a security threat. That way, they can stop any security threats before they happen. Since these machines are a pivotal part of airport security, knowing the different types of scanners and how they work can help you know how to utilise them best.
