The Injection Pump Shield is designed to reduce technologist exposure during the injection of radionuclides that require a very slow infusion protocol using Graseby #3100 or #3400 Syringe Pumps. The shield is constructed with 0.5"-thick lead to attenuate I-131. A lead glass viewing window allows the technologist to see the syringe during the infusion. The cover can slide lengthwise to reveal the syringe stopcock for adjustments, without exposing the syringe.
