Recently, many customers consulted the physical effects of security inspection X-ray machines. Fangji Infinite x-ray security inspection equipment collected some relevant data and explained the physical effect of x-ray security inspection machine in detail:


1. Fluorescence
Because the wavelength of the safety X-ray machine is very short, it cannot be seen. However, when it is irradiated on phosphorus, platinum barium cyanide, zinc sulfide, calcium tungstate and other compounds, the atoms are in an excited state due to ionization or excitation, the atoms return to the ground state process, and visible light is radiated due to the valence electron energy level transition Or ultraviolet light, that is fluorescence. The safety X-ray machine makes the material's fluorescence attack sensitive to fluorescence, which is called fluorescence induction. The fluorescence intensity is inversely proportional to the number of X-ray machines that have undergone security inspection.

2, security X-ray function of heat sensitive materials

A part of it is converted into heat energy, thereby reducing the temperature of the object, which is called thermal induction.

3, penetrating influence


Penetration effect refers to the ability to not collect safety X-ray machines when passing through materials. The safety X-ray machine can penetrate substances that cannot be penetrated by ordinary visible light. Because the wavelength of the photon is very long, its energy is very small. When it hits an object, a part of the object is reflected, a large part of which is arranged by matter and cannot pass through the object; and the safety X-ray machine is like this, engulfing its wave of black and white light and energy, irradiating the material Only part of it is released by the substance, and most of it passes through the gap between atoms, showing strong penetration ability. The ability of the safety X-ray machine to penetrate the material has nothing to do with the photon energy of the safety X-ray machine, and the shorter the wavelength of the safety X-ray machine.

4, intervention, diffraction, reflection, refraction

These effects are the same as visible light. It has lost use in safety X-ray microscopy, wavelength measurement and material structure analysis.

5. Ionization
When the material is irradiated by the X-ray of the security inspection machine, the electrons outside the atomic nucleus are removed from the atomic orbit. This effect is called ionization induction. In the process of photoelectron effect and scattering, the process of photoelectrons and recoil electrons leaving the atom is called primary ionization. These photoelectrons or recoil electrons are entering and colliding with other atoms, which causes the electrons to escape from the atom being hit. In solids and liquids. The positive and negative ions after ionization will be recombined soon, and it is not easy to collect.
