Application of high specific gravity tungsten alloy in medical shielding

       High specific gravity tungsten alloy shield

Why do you need high specific gravity tungsten alloy shields?

With the development of medical technology, more and more radiation devices appear in our lives. The spread of medical equipment and nuclear power plants has had a major impact on our lives. The hazard of radiation and how to protect people from radiation has aroused great concern. Therefore, shielding against radiation such as X-rays, gamma rays (high-energy electromagnetic radiation), alpha particles (helium atoms), beta particles (electrons), and cosmic rays is necessary.







To protect patients, doctors, nurses, and others from radiation, radioactive sources must be isolated and shielded. The radioactivity of radioactive materials must be controlled at low enough radiation levels to avoid harmful ionizing radiation so that it does not cause cancers such as lung cancer, skin cancer, etc. Lead and iron are traditional radiation shielding materials, but there is no doubt that high specific gravity tungsten alloy shields are the best choice. The reason why high specific gravity tungsten alloy shields are selected as shielding materials is that tungsten alloys have excellent radiation absorption capacity, high density (two times higher than lead) and good corrosion resistance.



Advantages of high specific gravity tungsten alloy shields





The radiation shielding properties of a material are closely related to the density of the material. Higher density means better radiation absorption and radiation shielding. Due to the higher density of tungsten alloys than other materials, the high specific gravity tungsten alloy shields have better radiation absorption and shielding ability than other traditional shielding materials, such as lead. High specific gravity tungsten alloy shields have better shielding properties for gamma rays, thereby reducing the volume of the shields. Compared with lead, the same volume of high specific gravity tungsten alloy shield has better radiation shielding.



Because tungsten alloy combines high density (60% higher density than lead), machinability, good corrosion resistance, and high radiation absorption (better than lead and steel), high strength, tungsten alloy is the best shielding member raw materials. By reducing the volume and thickness of shields and containers, tungsten alloy shields still have the same radiation shielding ability as lead. In addition, because tungsten alloys are non-toxic and pollution-free, high specific gravity tungsten alloys are more environmentally friendly than lead and depleted uranium.



Application of high specific gravity tungsten alloy

The use of high specific gravity tungsten alloy shields is not subject to NRC, EPA and special OSHA regulations. Therefore, high specific gravity tungsten alloy shields are widely used in the field of nuclear medicine as collimators, radioisotope containers, radioactive source containers, etc.
