The Z-PET Syringe Shield greatly reduces hand exposure from syringes containing 511 keV radionuclides. The barrel of the shield is constructed of .55" thick (14 mm) tungsten that attenuates FDG F-18 by 97%. The shield accommodates standard 5 cc syringes. The Manual Dose Injector is an ideal companion, providing both additional shielding and distance.
