The Comparison Between Lead and Tungsten Alloy in Radiation Shielding

Density: the density of tungsten alloy radiation shielding is almost 18.6g/cm3 while lead is only 11.34g/cm3, so at the same weights high density heavy alloy can provide the same energy absorption as lead using 1/3 less material. When the weight is certain, more density, and the thickness would be thinner. Tungsten alloy material could be made with thinner thickness but high absorption of radiation in high density. That is why tungsten alloy material is suitable for radiation shielding.

Environmental protection: tungsten alloy radiation shielding is less harmful to our health than lead material of radiation shielding; this is because lead is poisonous and is not good both to our body and the environment, so tungsten alloy is environmental friendly material.
