Applications of Medical Tungsten Alloy Radiation Shield
1. Radiotherapy - Treat malignant tumors with one or more ionizing radiations. Radiation shields (collimators, multi-leaf, etc.) on radiotherapy equipment such as medical electronic linear accelerators and cobalt-60 treatment machines are made of W-Ni-Fe alloy. Tungsten alloy shields can reduce the particle beam, so that the particle beam is irradiated in a specific direction, to limit the amount of radiation.
2. Medical imaging - A technique that uses CT scanners and other imaging equipment to accurately scan a section of a human body through X-ray beams, gamma rays, ultrasound, etc. to obtain medical images. Tungsten alloy tubes, tungsten alloy foils, and tungsten alloy plates on CT scanners can effectively absorb X-rays and γ-rays.
3. Radioactive tracing - Use radionuclides for medical diagnosis and treatment. A common tungsten alloy shield is a tungsten alloy syringe protective sleeve. When medical workers are injecting drugs to patients, or when scientific researchers are developing radioisotopes, it can protect the staff's arms from radiation.
