Tungsten Alloy Radiation Shielding in Linear Accelerator

Tungsten alloy radiation shielding in linear accelerator refers to radiation protection and beam-shaping components used in Medical Linear Accelerators (LINAC), primarily installed in treatment heads, collimation systems, and areas surrounding targets. Medical linear accelerators generate high-energy X-rays by accelerating electrons onto a target for cancer treatment, while the treatment head and beam path require shielding to control leakage and scattered radiation. CTIA’s tungsten alloy radiation shields provide high radiation attenuation and structural stability in limited installation space and are available as shielding blocks, collimator components, Multi-Leaf Collimator (MLC) leaves, and custom-shaped precision components for precise beam shaping and collimation in radiotherapy equipment.

1. Features of CTIA’s Tungsten Alloy Radiation Shielding in Linear Accelerator
(1) Efficient Radiation Shielding: Attenuate high-energy X-rays and scattered radiation through a density of 16.7–18.8 g/cm³, reducing shielding thickness while meeting radiation protection requirements.
(2) Precise Beam Control: Limit radiation propagation outside target directions through collimator and beam control components, improving treatment-field control.
(3) Structural Stability: Maintain reliable performance during long-term operation through high strength, wear resistance, and dimensional stability under mechanical movement and radiation exposure.
(4) Compact Integration: Reduce internal space requirements through compact shielding structures suited to precision equipment integration.
(5) Precision Machining: Support complex geometries, custom-shaped components, and high-precision dimensions for treatment heads and collimation systems.
(6) Long-Term Reliability: Maintain stable shielding performance and dimensional accuracy during prolonged radiation exposure and equipment operation.

2. Applications of CTIA’s Tungsten Alloy Radiation Shielding in Linear Accelerator
(1) Treatment Head Shielding: Installed inside treatment heads to attenuate stray radiation generated during X-ray and electron beam production and transport, reducing leakage radiation.
(2) MLC Leaves: Dynamically shape treatment fields through controlled leaf movement, enabling precise beam control and dose distribution modulation.
(3) Primary and Secondary Collimators: Define beam boundaries and reduce scattered radiation to improve control of the treatment field.
(4) Target-Area Shielding: Installed around targets and other high-radiation regions to reduce internal radiation exposure and protect surrounding components.
