Tungsten Alloy Radiation Shielding in Nuclear Medicine

Tungsten alloy radiation shielding, also known as tungsten alloy radiation shield, is radiation protection component used in nuclear medicine for diagnosis, treatment, and radiopharmaceutical handling. High-density tungsten alloys provide effective attenuation of γ-rays and X-rays generated by radionuclides, leveraging tungsten’s high atomic number and alloys’ high density. CTIA’s tungsten alloy radiation shielding includes syringe shielding sleeves, vial shielding containers, radioactive source containers, shielding covers, shielding blocks, and collimators for Positron Emission Tomography (PET), Single Photon Emission Computed Tomography (SPECT), and dispensing, storage, transport, and injection of radiopharmaceuticals.

1. Features of CTIA’s Tungsten Alloy Radiation Shielding in Nuclear Medicine
(1) Effective Radiation Attenuation: Density of 16.7–18.8 g/cm³, effectively attenuating γ-rays generated by radionuclides such as ¹⁸F, ⁶⁸Ga, ⁹⁹ᵐTc, and ¹³¹I, ideal for localized protection against high-activity radiopharmaceuticals.
(2) Compact Structure: Achieves effective shielding within confined spaces, making them suitable for installation inside syringes, vials, and nuclear medicine equipment.
(3) Precision Machining: Compatible with turning, milling, grinding, wire EDM, and CNC machining to fabricate inner cavities, shielding holes, viewing windows, and complex customized geometries.
(4) Operational Protection: Configurable with quick-release lids, locking mechanisms, and ergonomic structural designs, facilitating radiopharmaceutical dispensing, transport, and injection operations while reducing occupational exposure risks for healthcare personnel.
(5) Long-Term Stability: High strength, corrosion resistance, and dimensional stability support repeated operation and long-term use in nuclear medicine environments.
(6) Non-Toxic and Environmentally Friendly: Non-toxic and non-radioactive, with surfaces suitable for mirror polishing or medical-grade decontamination treatment, supporting repeated autoclave sterilization and chemical disinfection for nuclear medicine cleanliness and sterility requirements.

2. Applications of CTIA’s Tungsten Alloy Radiation Shielding in Nuclear Medicine
(1) Radiopharmaceutical Storage: Used for vial shielding containers, shielding containers, and storage protection structures for radiopharmaceuticals such as ¹⁸F-FDG, ⁶⁸Ga, ⁹⁹ᵐTc, and ¹³¹I.
(2) Radiopharmaceutical Transport: Used for shielding cans, shielding boxes, and protection containers during the internal transport of radiopharmaceuticals and radioisotopes within hospitals.
(3) Radiopharmaceutical Dispensing: Used in shielding components for nuclear medicine hot cells and dispensing areas to reduce scattered radiation during radiopharmaceutical preparation.
(4) Injection and Administration Protection: Used for syringe shielding sleeves and localized shielding components to reduce radiation exposure to medical personnel’s hands and bodies during drug withdrawal and injection.
(5) PET and SPECT Equipment: Used for collimators, shielding blocks, and localized shielding structures around detectors in PET and SPECT equipment to reduce the effects of scattered radiation on detection systems.
(6) Radionuclide Generators: Used for localized shielding components in equipment such as ⁹⁹Mo-⁹⁹ᵐTc generators, providing radiation protection during radionuclide preparation and handling.
