Cobalt 60 tungsten alloy radiation shield may be some tungsten alloy leaves applied to the collimator of a cobalt-60 radiotherapy machine, or a tungsten alloy container used for storage and transportation of cobalt-60. Generally, such a radiation shielding product has characteristics of high density and high ray shielding performance. And it is non-toxic and environmental friendly. More importantly, tungsten alloy shields have better radiation shielding performance than traditional lead shields.

Why is a cobalt 60 tungsten alloy radiation shield necessary? Cobalt-60 is a strong gamma source and is commonly used in medical radiotherapy for cancer and tumors. However, cobalt-60 is extremely radiant to cause hair loss, seriously damage the cells and tissues in the blood of the human body, cause leukopenia, and cause blood system diseases such as aplastic anemia, severe cases can cause leukemia and even death. Therefore, tungsten alloy containers are used for the sealed storage and transportation of cobalt-60. In addition, there are also some tungsten alloy leaves on the head of cobalt-60 treatment machine to reduce strong radiation generated by cobalt-60.
