Table 3 The radionuclide inventory of the 43Sc eluate, isolated from irradiated 46Ti and 43CaCO3 targets is shown, together with the calculated values at EOB. Cross section data for the nuclear reactions 46Ti(p,α)43Sc, 43Ca(p,n)43Sc and 44Ca(p,n)44Sc were taken from Carzaniga et al. (Carzaniga et al. 2017), while the data for all other nuclear reactions was retrieved from the TENDL 2015 database (Koning et al. 2015)
