When it comes to shielding from radiation, denser materials offer superior protection. This is because heavy elements have a high capacity for absorbing X-rays and gamma radiation.

Lead, a commonly used shielding material, poses environmental and health risks due to its toxicity.

Tungsten boasts a density 60% higher than lead, allowing for effective shielding with thinner layers. Tungsten alloy, therefore, emerges as an optimal choice for radiation shielding.

Applications for the medical industry include collimators, shielding blocks, and nuclear equipment. Notably, tungsten heavy alloy, with grades such as HA180 and HA185, stands out for its effectiveness in radiation shielding. These alloys are excellent materials for shielding and collimation due to their combination of radiographic density, machinability, strength, and low toxicity. Compared to lead, tungsten heavy alloy offers superior protection at similar thicknesses while maintaining resistance to deformation and enabling accurate fastening.
