Online radioactive decay calculator that allows you to find out the radioactivity decay in Sodium (Na) 22. Note: The calculation of radioactivity in minerals is based on certain assumptions. Na‐22 11 protons 11neutrons E(MeV) # per 100 Dis 1.275 100 Bench Top Quantity Must Be Less Than 4000 µCi Containers Require Labeling When Greater Than 10 μCi Rooms Require Posting When There Is Greater Than 100 µCi The ratio of electron capture to positron emission in the decay of Na²² to the 1.28-Mev level in Ne²² has been determined by a comparison of the intensities of positron emission and 1.28-Mev radiation. The measurements were made with a coincidence arrangement employing a 4π beta counter to detect the positrons and a scintillation counter for the γ rays.
