These days the security is really important for every place and if we check from the current security challenges of the world, there are different kinds of physical checkpoints, metal detectors, and baggage scanners are available in public places. Even at the airport also you will be able to see that there is a very tight security available who will check all the stuff that will be carried by the passengers. The security process is designed to protect the people, the passengers, though most of the time this process is quite invasive it is really very important. When a person visits the airport then he or she has to go through the entire security process to check all the stuff that he or she carries.
It is very obvious that most of the people saw the x ray security scanner at the airport. Basically, the scanner at the airport can detect the metallic and non metallic objects on the body that including the drugs and gold which are hidden under the clothes or in the bag. Most of the times, they cannot detect the exact material but provide you the visual clues about the material or the object in the form of different colors that will be a great option for the security guards who are providing the service at the airport. Airports scanners are specially designed to detect the non metallic items on people's bodies that may escape the metal detectors and the scanner can see anything on the body under the clothes but cannot see inside the body. Sometimes checking the things manually will not be easy for the people and due to that this machine plays a very important role and at some extent, it provides the best security to the place.
When a person looks out for the airport x ray machine then it is very important to understand that how it works and what will be the use of using such machines. Mostly these machines are considered as the metal detector that will carry on the items that are on your body or in your bag. The machine has a conveyor belt that carries each item past x-ray machines and X-rays are like light in that they are electronic magnetic waves and they are more energetic so they can penetrate many materials. The machines that are used in the airport are based on a dual-energy x-ray system and this system has a single x-ray source sending out X rays which are typically in the range of 140 to 160 kilovolt. Once the x-ray passes through the item then they are picked up by the detector and the detector passes the X-ray onto the filter which blocks out the lower energy of X rays. And the remaining high-energy x-ray hits a second detector. It is a complete procedure of x-ray machine that how it will work, but at last, it will check the metal or nonmetal objects that are available on a human body or inside the bag.
