SUMMARY
Na-22 undergoes beta-plus (B+) decay and electron capture, emitting a positron that results in electron-positron annihilation, producing two gamma rays of 511 keV at 180 degrees separation. The 1274 keV peak observed in the spectrum of Na-22 originates from its decay to the first excited state of Ne-22, which subsequently de-excites and emits a gamma ray of 1274 keV. This process is crucial for understanding the gamma-ray spectrum associated with Na-22.
