Radiation Shielding with Tungsten Alloys

Radiation shielding plays an important role in nuclear medicine, specifically for handling radioactive materials. Tungsten alloys are used for shielding against radiation contamination in radioactive source containers used for transporting radioactive materials from PET isotope production centers to cancer treatment hospitals, and in syringe covers for injecting radioactive isotopes. H.C. Starck Solutions’ 3D printed collimator parts operate as gamma camera collimators and PET SEPTA plates are manufactured for collimation shielding in PET scanners.
