Description Of Press Fit Tungsten Alloy Syringe Safety Shield

Press Fit Tungsten Alloy Syringe Safety Shield Made of tungsten alloy material with high shielding level, it can accommodate 5 ml to 20 ml of syringes, and can install lead glass Windows and different types of locks according to the customer's needs, and can also customize the shielding thickness and size specifications according to the isotopes of different radiation doses. Press Fit Tungsten Alloy Syringe Safety Shield is designed to protect clinicians from the radiation exposure that clinicians receive when preparing and managing radiopharmaceuticals, with a decay rate of more than 90%.

Features Of Press Fit Tungsten Alloy Syringe Safety Shield

Efficient radiation shielding

The linear attenuation coefficient of tungsten alloy (density is usually ≥18 g/cm³) is much higher than that of lead (11.3 g/cm³), which can significantly reduce the penetration of gamma rays and X-rays, providing equivalent protection under a thinner wall design.

Precision press-fit structure

The interference fit technology (such as cold pressing or the shrink sleeve process) is used to ensure that there is no gap between the shield and the syringe to avoid radiation leakage and enhance mechanical stability.

Lightweight and compact

At the same protection performance, the volume of tungsten alloy shields is about 30% smaller than that of lead products, which is more suitable for handheld operation or narrow space use.

Corrosion resistance and long life

The surface is often nickel-plated or oxidized to resist chemical corrosion (such as disinfectants); the high hardness of tungsten alloy (300-400 HV) resists wear and extends service life.

Applications Of Press Fit Tungsten Alloy Syringe Safety Shield

Preparation of radiopharmaceuticals: When dispensing PET contrast agents (such as ¹⁸F-FDG), the shield shields high-energy 511 keV gamma rays to protect operators.

Therapeutic injection: Used in yttrium-90 (⁹⁰Y) microsphere therapy, etc., to ensure radiation safety during precise drug delivery.

Radiotherapy: In brachytherapy, the shield can safely carry sources such as iridium-192 (¹⁹²Ir), reducing the cumulative dose to medical staff.

Industrial testing: In non-destructive testing (NDT), it protects operators of flaw detection equipment containing radioactive isotopes (such as selenium-75).
