Products Description
Tungsten Transport Containers for FDG (Fluorodeoxyglucose, ¹⁸F) is a specialized shielded vessel designed to safely carry and store this radioactive tracer used in PET (Positron Emission Tomography) scans. Due to the high-energy positron (β⁺) and gamma (511 keV) emissions of ¹⁸F, tungsten's exceptional density (18–19 g/cm³) provides superior shielding compared to lead or steel, while maintaining a compact and lightweight design.
Features of Tungsten Transport Containers for FDG
1. Material & Shielding Performance
Tungsten alloy (W-Ni-Fe/Cu):
Higher density than lead (~2× better attenuation per unit thickness).
Blocks >90% of 511 keV gamma rays with thinner walls.
Lead-free: Non-toxic and environmentally friendly.
Optional inner liner: Some designs include lead or copper layers to enhance shielding further.
2. Design Specifications
Capacity: Typically holds 1–4 standard FDG vials (10–30 mL volume).
Structure:
Double-layered lid: Ensures no radiation leakage during transport.
Dedicated vial slots: Prevents breakage and minimizes vial movement.
Compliance: Meets IAEA (SSR-6) and DOT/IATA regulations for radioactive material transport.
3. Portability & Safety
Weight: ~20–50% lighter than equivalent lead containers.
Ergonomic handles: Facilitate easy carrying.
Surface markings: Include radiation trefoil labels and dose rate information.
Comparison: Tungsten vs. Lead FDG Containers
| Parameter | Tungsten Container | Lead Container |
|---|---|---|
| Shielding efficiency | Superior (thinner walls) | Requires thicker material |
| Weight | Lighter (~3–5 kg for 4-vial) | Heavier (~5–8 kg) |
| Durability | Corrosion-resistant, robust | Prone to dents/oxidation |
| Cost | Higher upfront cost | Lower initial cost |
| Regulatory approval | Compliant with transport laws | Compliant but may require more shielding mass |
Applications of Tungsten Transport Containers for FDG
Hospital/Radiopharmacy: Transporting ¹⁸F-FDG from cyclotron/PET facility to imaging centers.
Mobile PET Units: Shielding during on-site deliveries.
Research Labs: Safe handling of high-activity ¹⁸F samples.
