Tungsten is often specified for syringe shields in place of lead. It is easier for the technician or physician to transport and use.Gamma radiation and X-rays are absorbed most effectively by high-density materials. AT&M high-density materials are a family of tungsten-based materials with densities 50% greater than that of lead. The high-density, good mechanical strength and excellent machinability of AT&M materials tungsten alloy shielding makes them ideal for shielding applications.
Property of Tungsten Alloy Syringe Shielding
Tungsten content (wt%): 90-97
High density 16.0~18.5g/cm3
High strength 580~950Mpa
Good machining property
High thermal conductivity
Low coefficient of thermal expansion
High mass absorption coefficient
With a density in the range of 17g/cm3 to18.5g/cm3, tungsten alloy shielding takes up roughly two-thirds as much space as lead shielding and poses no environmental threat. CMW Inc. enjoys a long history of supplying tungsten high density metals used in radiation shielding for the medical, industrial and nuclear industries. Whether shielding radioactive material used in nuclear medicine, radiation therapy, or gamma-ray inspection units, CMW tungsten high-density metals make an excellent choice for your demanding application. Our tungsten high-density metals provide the properties required in radiation shielding for therapy as well as diagnosis. Common applications include collimators, syringe and vial shields, and radioactive source containers.
