• 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.

In and 22 58 Measurements of the electron capture to positron ratio in the decay of Na and Co are also described. Introduction 1. This paper is limited to those nuclear decay scheme parameters which are measured at NPL in conjunction with the programme* of standards of radioactivity viz - half lives, internal conversion coefficients, electron capture to positron ratios and y branching ratios.
