Tungsten Alloy Syringe Shield in Radiopharmaceutical Injection

Tungsten alloy syringe shield in radiopharmaceutical injection is portable, high-density radiation shielding components designed for radiopharmaceutical withdrawal and injection, primarily shielding β/γ radiation from radionuclides such as F-18, Tc-99m, I-131, and Ga-68. Compared with conventional lead syringe shields, CTIA’s tungsten alloy syringe shields provide more compact structures and thinner shielding walls under equivalent protection requirements, while offering high strength, non-toxicity, sterilizability, and operational flexibility. Tubular structures can be designed to fit standard syringes, with viewing or sliding windows available for drug observation and injection, effectively reducing radiation exposure to medical personnel’s hands and body.

1. Why Choose CTIA’s Tungsten Alloy Syringe Shield in Radiopharmaceutical Injection?
(1) High Density Delivers Superior Shielding Efficiency: Tungsten alloy typically has a density of 16.7–18.8 g/cm³. High atomic number and density provide effective attenuation of γ-rays from radiopharmaceuticals, delivering effective radiation protection within limited space.
(2) Compact Size Ideal for Handheld Operation: Compared with conventional lead shielding materials, tungsten alloy enables more compact shielding structures while maintaining required protection levels, making syringe shields easier to handle during injection.
(3) Reduced Hand Exposure: Medical personnel work in close proximity to radioactive sources during radiopharmaceutical injection. Tungsten alloy syringe shields provide localized shielding around the syringe, reducing scattered radiation exposure to the hands during operation.
(4) Precision Structural Design: CTIA designs the internal cavity, viewing window, and operating openings according to syringe diameter, capacity, and plunger structure, maintaining effective shielding while allowing smooth drug observation and injection.
(5) Suitable for Repeated Use: Tungsten alloy offers good strength, corrosion resistance, and dimensional stability. Polished and easy-to-decontaminate surfaces facilitate cleaning, disinfection, and long-term repeated use.

2. Applications of CTIA’s Tungsten Alloy Syringe Shield in Radiopharmaceutical Injection
(1) PET Radiopharmaceutical Injection: Used for injection of radiopharmaceuticals such as F-18 FDG during Positron Emission Tomography (PET), reducing radiation exposure to operators’ hands.
(2) SPECT Radiopharmaceutical Injection: Used for injection of radiopharmaceuticals such as Tc-99m during Single Photon Emission Computed Tomography (SPECT), providing localized γ-ray shielding.
(3) Nuclear Medicine Therapeutic Administration: Used during the administration of therapeutic radiopharmaceuticals such as I-131.
(4) Radiopharmaceutical Dispensing: Used in nuclear medicine hot cells and radiopharmaceutical dispensing areas to provide localized radiation protection during drug withdrawal, transfer, and syringe assembly.
