Tungsten Alloy PET Syringe Shield

1. What’s Tungsten Alloy PET Syringe Shield?
Tungsten alloy PET syringe shield is localized radiation protection component used during radiopharmaceutical injection in Positron Emission Tomography (PET) examinations, primarily for positron-emitting radiopharmaceuticals such as F-18 FDG. Positrons produced during F-18 decay annihilate with electrons to generate 511 keV γ-rays, exposing operators’ hands to radiation during radiopharmaceutical extraction and injection. CTIA’s tungsten alloy PET syringe shield provides effective attenuation of 511 keV γ-rays through tungsten’s high density and high atomic number while maintaining convenient hand-held operation.

2. Features of CTIA’s Tungsten Alloy PET Syringe Shield
(1) High Density, Strong Shielding: Provide effective 511 keV γ-ray attenuation with density of 16.7–18.8 g/cm³ and tungsten’s high atomic number.
(2) Compact Structure: Reduce wall thickness and overall dimensions through high-density material, making the sleeve suitable for hand-held, close-range operation during PET injection.
(3) Reduced Hand Exposure: Shield the syringe body and reduce radiation exposure to operators’ hands during radiopharmaceutical extraction and injection.
(4) High Strength, Stable Structure: Withstand impacts, handling, and repeated operation through high mechanical strength and wear resistance, maintaining structural stability during use.
(5) Clear Visibility: Provide optional lead glass viewing windows for observing syringe graduations, medication position, and injection procedures, improving operational visibility while maintaining shielding protection.

3. Applications of CTIA’s Tungsten Alloy PET Syringe Shield
(1) PET Radiopharmaceutical Injection: Extraction, transfer, and intravenous injection of PET tracers such as F-18 FDG, providing localized radiation shielding for operators’ hands.
(2) PET Radiopharmaceutical Dispensing: Dispensing of certain PET radiopharmaceuticals and syringe loading operations, reducing localized radiation exposure during close-range operations.
(3) Radiopharmaceutical Transfer: Localized shielding during short-distance syringe transfer, with dedicated shielding containers configured according to transportation methods and protection requirements.
(4) Nuclear Medicine Research and Clinical Operations: Research, clinical trials, and administration procedures involving PET tracers and other positron-emitting radiopharmaceuticals.
