• Expelling Na-22 solutions through syringe needles and pipette tips can generate airborne aerosols. • Use high-density (high Z) shielding material to shield Na-22 (lead). • Use remote handling tools when handling > 1 mCi of Na-22. Administrative Controls • Sealed and plated sources of Na-22 (>100 uCi) MUST be leak-tested and inventoried by RSS personnel once every 6 months.
