Description

technical field [0001] The invention relates to a composite material, in particular to a radiation medium (especially high-frequency electromagnetic wave) shielding material, as well as a preparation method and application of the radiation medium shielding material. Background technique [0002] X-rays are particle streams produced by the transition of electrons in atoms between two energy levels that differ greatly in energy, and are electromagnetic waves with wavelengths between ultraviolet rays and gamma rays. As a high-frequency electromagnetic wave, X-rays have short wavelengths, high energy, and high penetrating power. They can pass through many substances that are opaque to visible light, so they have been widely used in medicine and industry. [0003] However, X-rays are also harmful rays such as ionizing radiation and the like. On October 27, 2017, the list of carcinogens released by the International Agency for Research on Cancer of the World Health Organization w...

Problems solved by technology

[0005] For a long time, the X-ray radiation shielding material is mainly lead plate, although it can play a good shielding effect on X-ray radiation, but it mainly has technical problems such as high cost and poor corrosion resistance.

Undoubtedly, as a radiation shielding material, the lead plate will significantly increase the construction cost of the X-ray radiation environment or the buildings in the vicinity of the radiation environment, and at the same time, its poor corrosion resistance will affect its selection of the use environment. , if in order to enhance the corrosion resistance of the lead plate, it needs to be treated with corrosion resistance, which will increase the technical difficulty and cost
