Description of Nuclear Medicine 10ml Syringe Shield Base

The nuclear medicine syringe shield base—often referred to as a radiopharmaceutical shield—is a critical piece of personal protective equipment used in nuclear medicine departments to safeguard medical personnel against ionizing radiation. It utilizes high-density lead glass or pure lead as its primary shielding material. For common radionuclides such as Lutetium-177 (Lu-177), high-quality shield bases can achieve radiation attenuation exceeding 80%–97%; for low-energy gamma emitters like Technetium-99m (Tc-99m), they typically provide protection equivalent to 1.5 mm to 2.5 mm of lead. The 360-degree wraparound shielding structure ensures that the operator's fingers, palms, and arms remain within safe radiation exposure limits during use. Equipped with a high-density lead glass viewing window (density of approximately 5.2 g/cm³), the device allows medical staff to clearly read syringe graduations and verify liquid volume and the presence of air bubbles without opening the shield. Designed specifically to house syringes containing radioisotopes (such as Tc-99m, F-18, and Lu-177), the unit effectively attenuates gamma rays and beta particles through its high-density shielding materials, ensuring safety during drug dispensing, transport, and patient administration. Modern shield bases prioritize not only radiation protection efficacy but also ergonomic design and ease of operation, aiming to minimize occupational exposure risks while enhancing clinical workflow efficiency.

Safety Guidelines and Maintenance Recommendations of Nuclear Medicine 10ml Syringe Shield Base

Periodic Testing: Before each use, scan the surface of the shielding base with a portable dosimeter to confirm there is no abnormal radiation leakage. Periodically inspect the viewing window for cracks and check the shielding layer for damage.

Cleaning and Disinfection: Keep the inner and outer surfaces of the base clean to prevent the spread of radioactive contamination. Perform routine disinfection in accordance with hospital infection control standards.

Proper Storage: When not in use, store the shielding base in a designated radioactive material storage area; avoid mixing it with non-radioactive items and clearly mark it with the "Radioactive" warning symbol.

Compliant Operation: Strictly adhere to the ALARA principle (As Low As Reasonably Achievable)—keeping radiation doses as low as reasonably achievable—by employing comprehensive protection measures based on the three key factors: time, distance, and shielding.
