Tungsten radiation-proof material may be a tungsten alloy material, tungsten resin (tungsten polymer/tungsten rubber) material, or a tungsten-containing composite radiation-proof material. And these tungsten radiation-proof materials all have better comprehensive performance than traditional lead radiation-proof materials, such as stronger radiation protection effect, and higher hardness.

Tungsten-containing composite radiation-proof material refers to a compound composed of tungsten, lead, and barium compounds in a certain proportion, plus a radiation-resistant and aging-resistant unsaturated polyester resin as a molding material, with roving and glass fiber cloth as reinforcement materials, is cured at room temperature. Compared with the traditional lead shield, the shield made of tungsten radiation-proof material has good attenuation curve, good formability, and small scattering. So, it can be used to clinical diagnosis for X-ray protection. Besides, it is believed that tungsten radiation-proof materials will replace lead materials as they are non-toxic while lead is toxic.
