　　X-ray machines are mainly divided into medical X-ray machines, that is, medical X-ray machines, and the other type is the luggage X-ray machines that are most commonly used in stations, airports, customs and docks, so some people also call them X-ray luggage security inspection machines or security inspection X-ray machines. However, some people also have doubts: What is the difference between the two? Does security inspection X-ray machines have radiation hazards?In addition to these aspects, baggage scanner machines The performance in other aspects is also relatively good, which has attracted everyone’s attention and research. https://secuzoan.com/

　　security x-ray machines

　　ZA100100D

　　The principle of security inspection machine is similar to that of medical X-ray machine

　　The principle of medical X-ray machine and security inspection X-ray machine is the same. X-ray machine has three parts. One is the tube, which emits X-ray radiation source. X-ray can pass through the material to see things that our naked eyes cannot see with ordinary light. There must be a tube or X-ray. Second, there must be a high-voltage transformer. The high-voltage transformer converts the general voltage into high voltage, and then provides the tube to generate electrons and then generate X-rays. This is the second part. The third part is the controller, which means how much X-ray I need to release. There must be a control board. All X-ray machines cannot escape this, whether it is X-ray or CT. Although its structure is very complicated, its structure should be the same.

　　Security X-ray machines have less radiation

　　The use of security X-ray machines is to put the luggage into the item scanning X-ray machine. After the inspection is completed, the passenger can take back his luggage and leave. The X-ray machine used for item inspection uses X-rays to pass through the object to obtain X-ray images, which are processed by computers and displayed on the computer screen to identify the image and evaluate the safety of the object. Although the principle is similar to the human body X-ray examination in the hospital, Professor Li Ziping believes that the dose of security X-ray machines should be less than the amount of X-rays irradiated to the human body. Because the security X-ray machine only needs to see the general shape of the object. Medical X-ray machines need to see the human body very clearly, so the radiation dose is greater.

　　Therefore, there is no need to worry too much about the radiation problem of security X-ray machines. In addition, whether the radiation of security X-ray machines has an impact on the human body depends on the amount of radiation received at one time, the total amount of radiation received, the radiation time, and the human body’s regulation of these radiations. Moreover, even if the security inspection machine leaks due to quality problems, it may have an impact on the staff who work nearby for a long time, but it will not have much impact on people who pass by. It is understood that the country implements a licensing management system for the use of nuclear technology. X-ray baggage inspection equipment is a Class III radiation device, which is a low-risk radiation device.
