Description of Tc-99m Tungsten Alloy Syringe Shield

The Tc-99m Tungsten Alloy Syringe Shields are protective containers that must be equipped when injecting drugs into patients before nuclear medicine examinations. They can help medical staff effectively shield harmful ionizing radiation emitted by radionuclides. The main shielding effect is provided by high-density tungsten alloy and lead glass. Lead glass can provide doctors with a clear observation area. The Tc-99m Tungsten Alloy Syringe Shields provided by our company can be installed with screw locks to fix the syringe to avoid the risk of drug leakage caused by accidental slipping.

Features of Tc-99m Tungsten Alloy Syringe Shield

A dense tungsten alloy, only 5 mm dense-feeder Pb equivalent, already knocks 140-keV gamma to under 1% ambient, so operators stay under threshold with no fuss.

Windows of high-lead glass or tough PMMA, 9 to 10 mm, with crown etched scale marks for dose assessment. Both clarity and gamma shield are served, so peeking scales isn’t a breach. 

The cap’s quick-release flips or unscrews, yielding a cage that locks 1 to 10 mL syringes the way a freezer locks food; a side Luer port feeds the syringe right through the closed cap, skipping the bother of uncrewing completely.

The electrochemically polished layer springs back from corrosive spills and wipes with a cloth. Weight checks at 30% lighter than the same geometry in solid lead, so the wrist stays crisp for long cases.

Applications of Tc-99m Tungsten Alloy Syringe Shield

This protective cover is widely used in nuclear medicine departments, SPECT-CT centers, and radiopharmacy: it significantly reduces the hand dose of technicians, nurses, and transport personnel when packaging, transporting, and bedside injecting 99mTc-MDP, 99mTc-MAA, 99mTc-MIBI, and other radioactive drugs.
