Tungsten Alloy Radiation Shielding in Radiopharmaceutical Protection

Tungsten alloy radiation shielding in radiopharmaceutical protection refers to radiation shielding components used for storage, dispensing, transport, and injection of radiopharmaceuticals such as F-18 FDG, I-131, Tc-99m, and ⁶⁸Ga. CTIA’s tungsten alloy shielding components are manufactured through powder metallurgy and precision machining, using high density and atomic number to effectively attenuate β/γ radiation for localized protection during radiopharmaceutical handling in nuclear medicine.

1. Features of CTIA’s Tungsten Alloy Radiation Shielding in Radiopharmaceutical Protection
(1) Efficient and Lightweight Shielding: Density of 16.7–18.8 g/cm³ provides good attenuation of radiation from radiopharmaceuticals, enabling more compact structures under equivalent protection levels for easier one-handed operation and frequent transport.
(2) Non-Toxic and Sterilizable: Non-toxic and non-radioactive, with surfaces suitable for mirror polishing or medical-grade decontamination treatment, supporting autoclave sterilization and chemical disinfection for clean radiopharmaceutical handling.
(3) Precision Sealing and Easy Operation: Quick-release covers, tapered holes, sliding windows, magnetic or threaded locking structures facilitate drug withdrawal, dispensing, and transport while reducing radiation leakage during operation.
(4) Long-Term Stability and Durability: High strength, corrosion resistance, and dimensional stability support frequent clinical operation and long-term use.

2. Applications of CTIA’s Tungsten Alloy Radiation Shielding in Radiopharmaceutical Protection
(1) Injection and Administration: Used for syringe shields, suitable for injection of radionuclides such as F-18 and Tc-99m, reducing radiation exposure to medical personnel’s hands and bodies.
(2) Vial Storage and Dispensing: Used for vial shields and PET-specific drug containers for the safe storage, dispensing, and temporary storage of high-activity radiopharmaceuticals.
(3) Transport and Delivery: Used for portable transport containers and double-lid shielding containers to support the safe transport of radiopharmaceuticals from hot cells to wards, imaging rooms, and other areas.
(4) Hot Cell Operations: Used for hot-cell shielding inserts, localized protection covers, and dispensing shielding components to provide localized radiation protection during the preparation, dispensing, and handling of high-activity radionuclides.
(5) Specialized Radiopharmaceutical Protection: Used for dedicated shielding containers for I-131 therapy drugs, multi-vial dispensing systems, and emergency dose protection components to meet shielding requirements for different radiopharmaceutical handling scenarios.
