Tungsten Alloy FDG Containers

1. What Are Tungsten Alloy FDG Containers?
Tungsten alloy FDG containers are radiation shielding containers designed for the storage, transportation, and handling of Fluorodeoxyglucose (¹⁸F-FDG) and other positron-emitting radiopharmaceuticals used in Positron Emission Tomography/Computed Tomography (PET/CT) procedures. CTIA’s tungsten alloy FDG containers are made by tungsten heavy alloy and optimized for ¹⁸F-FDG applications, providing effective attenuation of 511 keV γ-rays and reducing radiation exposure during radiopharmaceutical preparation and operation. Tungsten alloy containers are widely used in nuclear medicine environments where radiation safety, operational efficiency, and long-term reliability are required.

2. Features of CTIA’s Tungsten Alloy FDG Containers
(1) 511 keV Gamma-Ray Shielding: High density of 17.0–18.5 g/cm³ and tungsten’s high atomic number provide effective attenuation of γ-rays emitted by ¹⁸F-FDG, ensuring reliable radiation protection during handling and storage.
(2) Compact Structure and Portability: Reduced wall thickness and container size under equivalent shielding requirements improve portability and support convenient operation in nuclear medicine environments.
(3) Durable Mechanical Performance: High strength, hardness, and wear resistance withstand repeated handling, dispensing, and cleaning operations, ensuring long-term service stability.
(4) Clean Surface and Flexible Design: Smooth surfaces support easy cleaning and disinfection, while customized structures such as magnetic covers and threaded locking designs meet different operation requirements.
(5) Lead-Free Medical Safety: Lead-free tungsten alloy materials eliminate lead contamination risks and meet safety requirements for medical and radiopharmaceutical applications.

3. Applications of CTIA’s Tungsten Alloy FDG Containers
(1) Radiopharmaceutical Preparation: Used for temporary storage, dispensing, and dose preparation of ¹⁸F-FDG after synthesis, reducing radiation exposure during high-activity drug operations.
(2) Hospital Drug Transfer: Used for transportation of FDG radiopharmaceuticals between preparation areas and PET/CT injection areas, improving radiation safety during internal transfer.
(3) PET/CT Injection Procedures: Used for syringe transfer, drug handling, and patient administration to reduce radiation exposure to medical personnel.
(4) Radioactive Waste Storage: Used for temporary storage of residual FDG drugs, used syringes, and radioactive waste materials, reducing radiation impact in storage areas.
(5) Radiopharmaceutical Transportation: Used as shielding packaging for FDG transport between hospitals and regional distribution centers, ensuring safe handling of radioactive materials.
