Tungsten Alloy Syringe Shield Description
Tungsten alloy syringe shields are generally immediately available in most volumes, including bulk quantities. Radiation therapy requires the injection of radiopharmaceuticals into the body through an injection catheter. During the course of radiotherapy, radiopharmaceuticals are stored in a large tungsten alloy medical shield to protect patients and medical personnel from radiation damage. Tungsten alloy syringe shield, also called injection shield, is designed to reduce hand exposure to radioactive injection for medical use. With great ability of radiation shielding, the barrel of the tungsten alloy syringe shield could be 0.06"-0.08". Tungsten alloy syringe shield could reduce radiation exposure from Tc-99m by more than 99%.
