DESCRIPTION
Tungsten Radiation Shielding for Nuclear Medicine – Safe, Compact & Lead-Free Protection
Why Tungsten in Nuclear Medicine?
Tungsten alloys (WNiFe, WCu) are the premium choice for medical radiation shielding due to:
Ultra-High Density (18–19.3 g/cm³) – 1.7X denser than lead, allowing thinner, lighter shielding.
Non-Toxic & Eco-Friendly – Lead-free (REACH/ROHS compliant), safe for hospitals/labs.
Superior Attenuation – Blocks 99% of gamma rays (Tc-99m, I-131, FDG) at minimal thickness.
Durable & Corrosion-Resistant – Withstands repeated sterilization (autoclave, chemicals).
Key Tungsten Shielding Products for Nuclear Medicine
Component Medical Use Case Key Features
PET/CT Shielding Blocks Scanner room walls Custom-cut panels (5–50mm thick)
Syringe Shields Radiopharma injections Tungsten-lined, ergonomic grips

Technical advantages over Lead
Parameter Tungsten Alloy Lead Improvement
Attenuation @ 511 keV (PET) 90% at 10mm 90% at 20mm 50% thinner
Weight for Equivalent Shielding 5 kg 8.5 kg 40% lighter
Lifespan 10+ years (no degradation) 3–5 years (oxidizes) 2X longer
Regulatory Status No restrictions Banned in EU healthcare Future-proof
Applications in Nuclear Medicine
PET/CT & SPECT Imaging – Tungsten shields reduce scatter radiation, improving image clarity.
Radioisotope Labs – Safe handling of Lu-177 (therapy), Tc-99m (diagnostics).
Brachytherapy – Tungsten capsules for I-125/Y-90 seed storage.
Veterinary Oncology – Compact shields for animal PET scans.
Customization Options
Thickness: 1–100mm (laser-cut to CAD specs).
Alloys: WNiFe (standard) or WCu (better heat dissipation).
Coatings: Antimicrobial, non-reflective, or color-coded finishes.
