Tungsten alloy shielding part is the first choice of radiation shielding. It can be used in the medical field and industrial field. Compared with the traditional shielding materials (such as lead), the shielding function of the tungsten alloy shielding part is much better than others. Due to its high density, the volume of the tungsten alloy shielding part is 1/3 smaller than lead, but shielding function is equivalent. At present, people have to make full use of shielding with tungsten alloy shielding part, using them for the radiation source container, gamma ray and X ray shield etc. they also are used as collimators and shielding members for radiotherapy and syringe shield.
