With the rapid development of social economy and science and technology, the metal detector, a device that can perform people screening, has undergone several generations of detection technology changes, from the initial signal simulation technology to continuous wave technology, to the digital pulse technology used today, metal. The detector introduces a variety of scientific and technological achievements based on the principle of simple magnetic field cutting. The application field has also been extended to multiple industries with the improvement of product quality. So, do you really understand the metal detectors that can be used for people screening? Can it only be used for people screening? The following article gives a brief introduction to the metal detectors that can be used for people screening.

Safety inspection is one of the contents of safety inspection in public places. All people and their belongings must be checked when they pass by, which is also one of the important precautions for passengers' personal safety. Therefore, X-ray screening technology has been widely used and developed

​With the development of society and economy, X-ray Screening has been widely used in various fields, but it has also been slowly discovered by some people. Due to the occurrence of nuclear accidents and nuclear accidents in Japan in the past few years, the panic of nuclear radiation has been spreading all over the world. The shadow of "talking about radiation color change" triggered by "talking about nuclear color change" has quietly enveloped people's minds. While the community is paying close attention to the impact of “nuclear radiation”, the security industry is also conducting a heated discussion about whether X-ray Screening equipment is “safe”. The following article briefly introduces X-ray Screening. Security issues and corresponding security protection knowledge. I hope to help you better understand X-rays.
