The decay process can be understood more clearly from the decay scheme. It can then be seen that gamma emission at 1294 keV is due to transitions from the excited level at 1.294 MeV to the ground state of K 41

12.8 days β+ decay is energetically possible only if the mass of the parent atom exceeds the mass of the daughter atom by at least two electron masses (2 x 0.000549 AMU or its energy equivalent, 1.02 MeV).

annihilation gamma. This is a special spectrum, it was taken with PRA 5.0 using two sodium iodide detectors, in coincidence counting mode, to detect the annihilation gammas that are produced when 22Na undergoes beta+ decay. The positron instantly annihilates with an electron, producing two 511 keV gammas at a 180˚ angle. The two diametrically

For reasons that remain unclear, the uptake of this loan scheme was disappointing. See for Museum of Art in a far-advanced state of decay.
