Abstract: A very brief overview of the hitherto investigated production routes of 86gY is given, and a comparative analysis of its production via the two low-energy reactions, namely (p,n) and (d,2n) on 96.4% enriched 86Sr as target material, is presented. Based on our recent cross- section measurements, the calculated yields of 86gY via the two reactions were compared, and the levels of co-produced isotopic impurities were estimated. At low-energy medical cyclotrons (Ep < 20 MeV; Ed <10 MeV) the use of the (p, n) reaction is superior, both in terms of the yield of 86gY and the levels of radionuclidic impurities. At medium-sized cyclotrons, on the other hand, the (d, 2n) reaction leads to higher yield of 86gY, but the level of radionuclidic impurities is also higher. The method of choice for production of 86gY thus remains the (p,n) reaction on enriched 86Sr.
