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.

It was also observed that the 507 kev gamma radiation occurs in coincidence with a BETA component, whose maximum energy iies between 246 and 332 kev. A new decay scheme is proposed.

22Na is an excellent source for a simple gamma-gamma coincidence experiment. The decay scheme for this isotope is shown in Fig. 13.1. From the diagram, it can be noted that 99.95% of the time the decay occurs by positron emission or

Na disintegrates by electron capture and β. + emission to excited level of 1274-KeV in. 22.
