Medical tungsten alloy radiation shield has a wide application in absorbing and guiding radiation for clear CT images, and for protecting patients from excess X-ray or γ ray radiation. And it is attributed to the advantages of tungsten alloy.

Medical tungsten radiation shielding material is a class of radiation protective material that has high radiation shielding performance and environmental protection characteristics. There are two type of medical tungsten radiation shielding materials - tungsten alloy materials and tungsten polymer materials. And they are the first choice materials for manufacturing medical radiation shields for different applications.

Tungsten alloy anti-scatter grid is applied to a CT device to absorb harmful scattered radiation, thereby significantly improving the quality of CT imaging and reducing the radiation dose received by patients. This is because the selected high-quality tungsten alloy raw material has strong radiation absorption and shielding ability. Studies have shown that with the same thickness, the radiation shielding ability of tungsten alloy is more than 1.7 times that of lead. And the difference between the two materials’ ability to shield X-ray becomes more obvious when the radiation is stronger.

Tungsten alloy sheet is applied for a CT detector (X-ray detector) to shield X-ray radiation. Tungsten alloy sheet is made of W-Ni-Fe alloy - an alloy composed of a small amount of nickel, iron and other alloying elements using tungsten as the matrix, and has a high density (~18.8g/cm3) and a high energy ray absorption capacity (1/3 higher radiation absorption coefficient than lead), so that it is widely used in the radiation protection and guidance of CT detectors to provide radiation protection for medical workers, patients and their family members.
