Pure Tungsten and Tungsten Alloys as Medical Radiation Shielding Materials
In medical fields, effective ionizing radiation shielding is vital. Pure tungsten, with a high melting point above 3400 °C and density around 19.25 g/cm³, weakens radiation through photoelectric absorption and Compton scattering. It s used as thin sheets for dental X-ray protection.
Tungsten alloys, mainly tungsten with other metals, offer good machinability and a density of 17 - 19 g/cm³. They can be shaped into complex forms for radiotherapy collimators and CT scanner operator protection. Selection depends on radiation type, shielding needs, and cost. Both are reliable options.
