How to understand x-ray layering

X-rays (X-rays) are high-energy electromagnetic radiation generated by the interaction of high-energy electrons with matter, with short wavelengths, generally between 10nm and 0.1nm, and great penetrating power, which can make photographic film photosensitive, fluoresce certain substances, and free gas. x-rays have been widely used in clinical diagnostics and treatment, such as X-rays, chest X-ray, photography, abdominal radiographs, cholecystograms, and other medical procedures. X-rays are widely used in clinical diagnosis and treatment, such as X-ray chest radiography, radiography, abdominal plain film, cholecystography, gastrointestinal imaging and angiography, etc. The layering of X-rays mainly refers to their ability to penetrate different substances to different degrees; when X-rays penetrate a substance, the energy of X-rays varies according to the atomic number and density of the substance, which causes X-rays to show different degrees of attenuation and scattering when they penetrate different substances, thus producing a layering effect. In addition, the short wavelength and high energy of X-rays also make them highly penetrating, and they can pass through many common substances, such as air, wood, paper, skin and so on. However, when the X-ray penetrates the material, its energy will gradually be absorbed or scattered, making the intensity of the X-ray gradually weakened, which also provides the basis for the layered sense of X-ray.
