The gamma knife is used to treat brain tumors by administering high-intensity gamma radiation therapy in a manner that concentrates the radiation over a small volume. A gamma knife typically contains 201 cobalt-60 sources of approximately 30 curies each (1.1 TBq), placed in a hemispheric array in a heavily shielded assembly. However, ionizing radiation has a damaging effect on the human body, and excessive radiation exposure does great harm to the human body. Therefore, a safe and reliable protective material - tungsten alloy is necessary for manufacturing shields. Therefore, tungsten alloy radiation shields such as tungsten alloy collimator is used for the gamma knife.
