What is X-ray
X-ray is a flow of particles generated by electron transitions in atoms between two levels, with many different energies. They are electromagnetic radiation with wavelengths between ultraviolet and gamma rays. The X-ray wavelength is very short, between about 0.01 and 100A. It was founded by German physicist W. K. in 1895. X-ray has high penetration and can make many materials opaque to visible light, such as ink paper, wood and so on. This invisible light can cause visible fluorescence of many solid materials, making photographic films and air ionization sensitive. X-ray was originally used in medical imaging diagnosis and X-ray crystallography. X-rays are also harmful radiation, such as free radiation.
Principle of X-ray
X-ray screening is now widely used in various fields. Do you know how X-ray works?
There is no essential difference between X-ray and natural light. They are all electromagnetic waves, but the energy of X-ray quantum is far greater than that of visible light. It can penetrate objects that cannot be penetrated by visible light. At the same time, it can interact with substances in complex physical and chemical ways. It can ionize atoms, make certain substances emit fluorescence, and make certain substances produce photochemical reactions. If there are defects in the local area of the work piece, the attenuation of light will be changed and the intensity of transmitted light will be changed. In this way, by using some detection methods, such as film sensitivity, to detect the strength of transmission lines, we can determine whether there are defects in the work piece and the location and size of defects. As long as the defect has a certain size in the transmission direction, its attenuation coefficient is different from the linear attenuation coefficient of the object, and the scattering rate is controlled within a certain range, we can get the contrast caused by the defect and find the defect.
Application of X-ray Screening Technology
1) Public places of entertainment
In recent years, due to frequent terrorist attacks in public places around the world, the security measures of large-scale venues have been gradually upgraded, and the security importance and awareness of the contractors of large-scale events in various countries have been rapidly upgraded to ensure that there are no potential security risks. X-ray equipment is also widely used in this field. It has stable performance and strong detection ability, and provides sufficient security for public entertainment places.
(2) Public Security System
With the increasingly prominent social contradictions and the increasingly serious anti-terrorism situation, public security organs, courts, procuratorates, prisons and other government organs often commit violent crimes and illegal acts, resulting in huge losses in personal and property security. Significant socio-economic impact. In order to prevent and stop explosions, shootings and murders and other violent incidents, the number of security equipment used by the public prosecution department has gradually increased. X-ray screening can be used in safety inspection machines.
(3) Industrial testing
X-ray screening can also be used in industrial testing. This technology can be used to detect automobile parts, aluminum and iron castings, hardware products, pressure vessels and so on, without causing damage to the articles.
Conclusion
Therefore,X-ray screening technology does bring great help to our life and work. It makes our living environment safer, the journey more stable, and also promotes the development of industry. After reading this article, do you have a better understanding of X-ray and X-ray screening techniques? If you are looking for economical, durable and safe products that can use X-ray screening technology, please choose us. I believe we are your ideal choice.
