Tungsten heavy alloy shield
The shielding parts of high specific gravity tungsten alloy are made of "high density alloy", which is based on tungsten and added with a small amount of Ni, Co, Mo and other elements. The density range is 16.8-18.8g/cm3.
As a new medical radiation shielding material, tungsten heavy alloy has many advantages: good corrosion resistance; low toxicity, lead-free; better radiation attenuation performance compared with lead; Higher mechanical properties of tungsten heavy alloy is better than lead, so more damage resistance; Tungsten heavy alloy can be processed into complex geometry; high hardness, high strength and good ductility make it have better durability than lead.
In recent years, radiotherapy has become a more commonly used treatment. Radiation medical equipment such as drill 60 treatment machine and linear accelerator has been widely used in hospitals. In order to achieve complete and reliable protection conditions, the key parts of the equipment and the organs that patients do not need to be irradiated must be made of various shapes of shielding parts made of anti radiation materials, such as radioactive source storage tanks, protective plates, etc.
Because of its excellent performance, tungsten heavy alloy shielding parts are widely used in the medical field. Tungsten heavy alloy can be X-ray collimator, pet injector shield, isotope container, FDG container, multi leaf collimator, etc.
