Advantages of tungsten alloy as medical shielding material
Tungsten alloy has the advantages of high density, good machinability, good corrosion resistance, high radiation absorption capacity and high strength. Widely used in aerospace, automotive industry and radiation shielding and other fields.
Tungsten alloys are best suited for applications where large weights need to be concentrated in the smallest possible space. Tungsten is about 1.7 times denser than lead, the traditional shielding material. The radiation shielding properties of materials are closely related to the density of materials. Higher density means better radiation absorption and shielding. As a result, it provides a higher degree of shielding. Lead alloy is a preferred shielding material for medical use.
This is a viable option for situations where lead cannot be used. Advantages of tungsten alloys include reduced size and maximum weight in large or small cavities used for radiation shielding. It is powerful and highly customizable for precision components. Tungsten alloy shield with high specific gravity has better shielding performance for γ rays and can reduce the volume of the shield. Compared with lead, high specific gravity tungsten alloy shield with the same volume has better radiation shielding performance. In addition, because tungsten alloys are non-toxic and pollution-free, they are more environmentally friendly than lead and depleted uranium. To prevent exposure, lead may need to be encapsulated or coated.
All in all, tungsten alloy is the material of choice for medical and industrial environments that require radiation shielding because it uses less material than lead to provide the same level of absorption. Tungsten is an excellent medical shielding material that ensures minimal radiation exposure and the "lowest reasonably possible" principle in the workplace. Machinability, radiographic density, strength, low toxicity and heat resistance have excellent design adaptability compared with other shielding materials. Tungsten alloy is the best raw material for shielding parts due to its high density (60% higher than lead density), machinability, good corrosion resistance, high radiation absorption ability (better than lead and steel), high strength. The tungsten shield still has the same radiation shielding capability as lead, although the volume and thickness of the tungsten shield are reduced.
