In nuclear medicine and related fields that involve radioactive materials, such as the preparation of radiopharmaceuticals, laboratory research, and industrial testing, the safety of personnel and the protection of the radiations are essential. For this fundamental requirement, we developed the tungsten syringe shield with a 2mm thickness and a protective grade of special technology. It is not an accessory that makes the work of personnel more comfortable; it is, in fact, an indispensable barrier to the working environment and safety of the medical and technical personnel. The protective device is manufactured of pure tungsten alloy, and the fabrication involves sophisticated powder metallurgy and precision machining. The ultimate protective performance, usability, and long-life of the shield are the core design principles. The wall thickness of 2mm is optimized, and shielded, weight, and structural strength are the parameters that have been engineered and tested in the optimum design to provide the best solution when the radioisotopes to be shielded are Tc-99m, I-131, or other members of the same nuclide family.
