Cs-137 tungsten alloy shield refers to tungsten alloy shield used to shield the cesium-137 radioisotope in medical applications. And it can also be used in agriculture and nuclear power plants.

Cesium-137 is a medical gamma radiation source. For example, cesium chloride injection can be used for heart scanning to assist in the diagnosis of myocardial infarction and its lesions. It can also be used to diagnose thyroid tumors and cancer treatment. And for radioactive injection solution, it requires a radiation shielding container for storage and transportation. Compared with traditional shielding materials such as lead, when the weight of the shield is the same, the volume of the tungsten alloy shield is smaller, only 1/3 of the lead, but the high density of tungsten alloy makes the shield have the same radiation absorption performance as a lead one. And tungsten alloy is non-toxic, while lead is toxic.
