Tungsten Alloy Radiation Shielding in Radiotherapy Equipment

Tungsten alloy radiation shielding in radiotherapy equipment refers to shielding and beam control components used in cancer treatment systems. W-Ni-Fe and W-Ni-Cu alloys are used in medical Linear Accelerators (LINAC), Gamma Knife systems, cobalt-60 therapy equipment, and proton therapy systems to attenuate high-energy X-rays, gamma rays, and particle beams, reducing radiation leakage and scattered radiation while enabling precise beam control and treatment-area protection.

1. Features of CTIA’s Tungsten Alloy Radiation Shielding in Radiotherapy Equipment
(1) High Density with High Shielding Efficiency: Attenuate high-energy X-rays and gamma rays effectively with 16.7–18.8 g/cm³ density and 90%–97% tungsten content, enabling thinner shielding layers and more compact equipment integration.
(2) Compact Dimensions for Easy System Integration: Reduce shielding thickness under equivalent attenuation requirements compared with traditional lead, fitting space-constrained precision assemblies such as treatment heads and collimators.
(3) Accurate Collimation for Precise Beam Control: Precision-machinable into Multi-Leaf Collimator (MLC) leaves, collimators, and shielding rings, to accurately shape radiation beams and improve treatment positioning accuracy.
(4) High Mechanical Strength for Stable Operation: Withstand continuous mechanical motion and radiation exposure through tensile strength of 700–1000 MPa, high hardness, wear resistance, and dimensional stability.
(5) High Machining Precision with Strong Structural Adaptability: Supports precision machining, wire EDM, EDM, and grinding/polishing to achieve complex structural geometries with tolerances down to ±0.01 mm, fulfilling high-precision assembly demands.
(6) Non-Toxic and Environmentally Safe: Lead-free compositions eliminate toxic contamination risks associated with lead, making them superior and safer for long-term clinical environments.

2. Applications of CTIA’s Tungsten Alloy Radiation Shielding in Radiotherapy Equipment
(1) LINAC: Supports treatment-head shielding, multi-leaf collimation, and beam-limiting structures for precise control of radiation fields.
(2) Gamma Knife Systems: Controls Co-60 gamma-ray propagation through collimators, shielding rings, and beam control components, directing multiple beams toward treatment targets.
(3) Cobalt-60 Therapy Equipment: Provides source shielding and collimation around radioactive sources to reduce radiation leakage and improve operational safety.
(4) Proton Therapy Equipment: Supports proton beam shaping and localized radiation protection through collimation and shielding components.
(5) Radiotherapy Equipment Shielding: Provides internal shielding and customized protective structures to reduce scattered radiation and support stable equipment operation.
