“…Fast neutrons react with 27 Al to produce 19 both 24 Na and 27 Mg; the latter can be separated from both the alumina starting material and sodium by chromatography, whilst 'waste' thermal DOI: 10.1039/b103037j neutrons from a power reactor have been used 20 to produce both 51 Cr and 60 Co. Proton beams have, however, proved 21 to be an efficient way of making 64 Cu [ 64 Ni(p,n) 64 Cu] and alpha particle irradiation of zinc 22 produces 68 Ge. This isotope, parent to 68 Ga, can also be made by proton bombardment of gallium [ 69 Ga(p,2n) 68 Ge]; alloying the gallium with silver makes 23 a convenient target. Both tin 23 and aluminium 24 oxides have been recommended as suitable substrates for radioactive germanium, from which the gallium-68 can be eluted as required, but a-iron(III) oxide is the preferred support 25 for 87 Y (made by 88 Sr(p,2n) 87 Y) in a generator for 87m Sr.…”
