Tungsten alloy shielding material is considered to be a new lead-free radiation shielding material with broad application prospects. It is environment-friendly and non-toxic, and has characteristics of high hardness, good corrosion resistance, excellent radiation absorption performance, strong mechanical properties, and high compressive strength.

Cobalt-60 tungsten alloy shield refers to tungsten alloy shield used on the cobalt-60 therapy apparatus, or the container used to store and transport cobalt-60, and so on. Cobalt-60 therapy apparatus is a large medical device that performs radiotherapy on tumors. Cobalt-60 is a kind of radiation with strong radioactivity (strong gamma source), which can be used to treat cancer, but it can cause hair loss, can seriously damage the cells and tissues in the human blood, cause the decrease of white blood cells, and cause blood system diseases, such as aplastic anemia can severely cause leukemia and even death.

Tungsten alloy vial shield is designed for vials containing liquid radioisotopes. Such a vial shield of tungsten based alloy has higher density than traditional lead vial shield so that it has better radiation absorption performance. It features a removable screw top with a magnetic cap. Speed of handling reduces exposure. Another design feature is the holding ring which fits comfortably in the hand or into a dispensing stand. The magnetic cap holds the lid in place even when inverted on the stand. Machined with 0.2" thick tungsten, the vial shield accommodates most 10 ml vials.

Tungsten alloy gamma ray shielding material overcomes the shortcomings of traditional lead shielding material, and is more often used in medical fields. More specifically, tungsten alloy gamma ray shielding material does not produce secondary bremsstrahlung, and has a high hardness, which can maintain a certain shape very well when it is made into large containers and large equipment. But if lead is used as the gamma ray shielding material for manufacturing large containers and large equipment, in order to avoid the collapse of the containers and equipment due to their own weight, it is necessary to use steel as the structural framework.
