Tungsten Alloy Radiation Shielding in Radioactive Material Storage

Tungsten alloy radiation shielding in radioactive material storage refers to shielding containers and structural components used for the safe storage and isolation of radioactive isotopes, radiopharmaceuticals, industrial radioactive sources, and radioactive materials used in research. CTIA uses 90W–97W tungsten alloy manufactured through liquid-phase sintering and precision machining, utilizing tungsten’s high density and high atomic number to effectively attenuate X-rays and γ-rays. The products can be machined into shielding cans, storage containers, protective cover plates, and sealing sleeves, with step joints, sealing grooves, and locking structures designed according to storage materials and shielding requirements. This enables effective radiation shielding within compact structures while maintaining mechanical strength, corrosion resistance, and long-term storage stability.

1. Features of CTIA’s Tungsten Alloy Radiation Shielding in Radioactive Material Storage
(1) High Shielding Efficiency: A density of 16.7–18.8 g/cm³ and tungsten’s atomic number of 74 provide effective attenuation of γ-rays and X-rays for reliable storage protection.
(2) Compact Structure: High-density material helps reduce shielding thickness and overall dimensions, making the shields suitable for space-limited storage applications.
(3) Reduced Radiation Leakage: Step joints and sealing grooves help reduce radiation leakage through structural joints.
(4) High Strength and Durability: High mechanical strength and wear resistance support repeated opening, handling, and long-term use.
(5) Corrosion Resistance and Easy Cleaning: Good corrosion resistance, polished surfaces, and easy-to-decontaminate treatment facilitate routine maintenance.
(6) Lead-Free: The lead-free material avoids potential contamination associated with lead and suits storage environments with cleanliness requirements.

2. Applications of CTIA’s Tungsten Alloy Radiation Shielding in Radioactive Material Storage
(1) Nuclear Medicine Pharmacy Storage: Used for temporary storage and local shielding of ⁹⁹Mo/⁹⁹ᵐTc generators, ¹³¹I, ¹⁷⁷Lu, and other radiopharmaceuticals and radionuclides.
(2) Industrial Radioactive Source Storage: Used for storage containers and local shielding structures for Ir-192, Co-60, and other industrial radiography and oil well logging sources.
(3) Research Isotope Storage: Used for the safe storage of radioactive samples, radioactive reference materials, and research isotopes associated with particle accelerators.
(4) Temporary Radioactive Waste Storage: Used for short-term storage and local radiation shielding of discarded radioactive sources, contaminated items, and other radioactive residues.
