WebFeb 24, 2024 · Abstract. Zirconium-89 (89 Zr), produced by the (p, n) reaction from naturally monoisotopic yttrium (nat Y), is a promising positron emitting isotope for immunoPET imaging.Its long half-life of 78.4 h is sufficient for evaluating slow physiological processes. A prototype automated fluidic system, coupled to on-line and in-line detectors, has been … WebAug 15, 2024 · 89 Zr decays to 89m Y, a short-lived daughter radionuclide with a 23 % β + emission and 77% EC [26, 27].Thereafter stable 89 Y is formed from the decay of 89m Y via gamma-ray emission (909.9 keV) [].The decay scheme of 89 Zr is given in Fig. 1 [].Despite the limited availability and the rather high gamma energies of 89 Zr, the low positron …
