Then for measurement (a), the rate Nis given by No = No Pep, (1) where No is the disintegration rate of the source, P is the fraction of the disintegrations to the 1.274 MeV level in which a positon is emitted, ais the efficiency of the counter to the positons.

Write the balanced equation for the positron emission decay of 22Na. Strong gamma-rays and decay data [in a detailed data page of each isotope] 2005/10/20: Information on spin and half-life shown in each nuclide page was K-43, Kr-85, La-140, Lu-177, Lu-177m, Mg-28, Mn-54, Mo/Tc-99m, Na-22, Na- 24, Nb-95, Ni-63, Np-237, P-32, P-33, Pb-203, Pb-212, Pd-103, Pd-109, Pm-149 With time, it became apparent that this classification scheme was much too simple.
