Recently, it was reported that a child in the Xiaolan station of the Guangzhou-Zhuhai intercity had not paid attention to drilling into the security inspection machine. The security personnel who saw this situation immediately stopped after the discovery and directed the child to climb out from the exit.

According to reports, in addition to the "bear children", there have been adults who climbed into the security inspection machine for various reasons and "frightened" many security personnel. At the beginning of this year, a monitor of a human security image appeared on the display of an security inspection machine at Dongguan East Railway Station, and the security personnel were stunned. After the security inspector responded, he immediately stopped. After the female passenger got out of the exit, she packed the luggage and rushed to the waiting room. Some reporters later learned that the reason why the female passenger showed such a "God operation" was because she was reminded by the security personnel that "the small bag had to go through security check", and she was afraid that the property in the bag would be lost, so she even brought the bag. Drilled into the security inspection machine.

We all know that security inspection machines are very common, fast bus (BRT), subway, railway station, bus station, airport, hotel, shopping mall, school, post office, large-scale events, conference center, convention center, government office building, embassy Such security check ports have such equipment. Its principle is to display the items in the trunk on the screen by means of X-ray perspective to identify suspicious objects and eliminate possible dangers in time.

It should be noted that although the radiation dose of X-rays in the security machine currently used is very low, it usually does not affect the health of people, and generally does not cause radiation pollution to articles and food. However, the radiation inside the security machine is still very large, and it will still cause certain damage to the human body. In other words, if a person directly "squats" into the security inspection machine, human health will still be affected.

It is reported that the radiation of the security inspection machine is mainly at the two ends - import and export. Therefore, when passing the security check, we should try to avoid facing the security inspection machine directly, and do not stay too long next to the security inspection machine, let alone open the security curtain, and even plunge the body into the object. The correct operation is to wait for the security items to “slip” out and then remove them. When passing the security check-in machine, parents with children should pay special attention to their children, so that the children can watch the anti-radiation curtains because of curiosity and even drill into the security machine to "over" the security check, thus causing unnecessary harm.

The reason why there is no need to open the security curtain, or even the body to explore the object, because the curtain of the security inspection machine is specially made, not an ordinary rubber curtain, it is a protective device to prevent X-ray leakage. Moreover, according to the information that the author learned from the security inspector, because the belt is not only the luggage of a passenger, if the curtain is opened casually, it will affect the scanning imaging of other luggage and cause image destruction. If it is necessary to re-examine, it is everyone's time. According to the security inspectors, it is best to take the objects half a meter away from the security curtain, because in the long-term consideration of personal health, we cannot take the initiative to contact if we can avoid it.

Having said that, the author has to talk about this security curtain. The security curtain can be either lead or tungsten polymer. Everyone should be familiar with lead curtains. The fisherman's earrings were made of lead, but most of them now use environmentally friendly tungsten alloy fishing sinkers. In other words, we all know that lead is heavy, toxic, and not environmentally friendly. The tungsten polymer security curtain is a new type of curtain prepared by combining tungsten and polymer. It has good radiation protection and can meet or exceed the density of lead curtain and X-ray shielding level. Moreover, it has good ductility and flexibility, is resistant to flexing, and has a soft texture. The most important thing is that tungsten polymer is environmentally friendly, non-toxic and harmless, will not pollute the environment, and will not cause harm to the human body. It is the best substitute for lead curtain material.
