90 Y is traditionally considered as a pure β – emitter. However, the decay of this radionuclide has a minor branch to the 0 + first excited state of 90 Zr at 1.76 MeV, that is followed by a β + /β – emission. This internal pair production has been largely studied in the past because it is generated by a rare electric monopole transition (E0) between the states 0 + /0 + of 90 Zr. The positronic emission has been recently exploited for nuclear medicine applications, i.e. positron emission… CONTINUE READING
