The ability of metal materials to absorb X-rays and gamma rays is proportional to their specific gravity. Previously, lead was widely used as a shielding material, the density of lead is 11.3g/cm3, while the density of tungsten alloy is more than 18g/cm3, so tungsten alloy has a stronger absorption of X-rays and gamma rays than lead, and the shielding capacity is more than 1.5 times that of lead. And lead material soft, easy to damage, and tungsten alloy hardness is high, the material is not easy to deformation damage. In addition, lead itself is toxic, and tungsten alloy materials are non-toxic and environmentally friendly. In summary, tungsten alloy has been widely used as a shield material to replace lead.

It is the best radiation shielding material in the medical field. Typical applications include radioactive source containers, collimators, radioisotope containers, syringe protective covers, etc.

To protect patients, doctors, nurses, and others from radiation, radioactive sources must be isolated and shielded. The radioactivity of the radioactive material must be controlled at sufficiently low radiation levels so as not to produce harmful ionizing radiation, so that it does not cause cancers such as lung cancer, skin cancer, etc. Lead is the traditional radiation shielding material, but there is no doubt that high-gravity tungsten alloy shielding is the best choice.
