At that time, every time I saw the parcel scanner machine, I would always want to crawl inside of the security inspection machine to find the principle of it.
I still remember the first time I saw the security inspection machine, at that time; I was very confused that if you want to get into the subway station, you have to send all your belongings to it. As most of the time, there won’t be anything that cannot be taken. I couldn’t understand why there is a security inspection machine. It is the age that I like asking why, so I ask mom the reason of the strange machine. Mom just tell me that the security inspection machine is magical the no matter what things are. More on walkthrough metal detectors.
The machine can tell whether there are any unsafe things that may cause accidents. At that time, what I understand accidents is that they can cause something bad, such like illness which is what I believe the worst thing. Thinking of this, I tried my best to get into machine to see whether I was in accidents or not. Obviously, I did not succeed. When I grow up, mom always tells me the story as a joke. Since then, I learned a lot about security inspection machine. The main technique of security inspection machine is X-ray. X-ray walk Through metal detector has great ability which is to penetrate things. This help the machine see many things that cannot be seen generally. Due to the unknown field of that whether X-ray does harm to people, the security inspection machine does allow people to get in.
Now, I work as an engineer of security walk-through metal detectors. My work in to make sure that the machine can run normally. Besides, I am not a screener. As a screener, I have to watch the screen of the security inspection machine to find that whether there are things that cannot be taken into the station. Although seeing other’s bags or boxes is like peeping other’s privacy, it is my mission to do so in order to guarantee the safety of the station. However, I also share a lot of things from the others. Sometimes I would see there is a delicate box in a boy’s backpack. Then I begin to image that it must a specially prepared gift for his girlfriend. I even would smile for a while, thinking that how happy the girl would be.
Obviously this would happen only when I am not busy with my work. In other words, there are not many customers in the station. Sometimes I would see fruits in a women’s bag. I believe that they may be her lunch as might be on a diet. And sometimes I may see elaborate meals. This could be the meal for the patient. It is really interesting to judge what the person is going to do with what they take, as the work is kind of boring.
