Selected terbium-155 production runs, indicating measured activity EOB and EOS for each run

Production No	Nuclear reaction	Irradiation time (h)	[155Tb]Tb EOB (MBq)	[155Tb]Tb EOS (MBq)	[155Tb]Tb EOS (MBq) (corrected to EOB)	Separation yield (%)
2	155Gd(p,n)155Tb	4	26.8	18.1	23.7	88.4
5	156Gd(p,2n)155Tb	4	705	487	555	78.7
7	156Gd(p,2n)155Tb	8	1250	829	1029	82.3
8	156Gd(p,2n)155Tb	8	1684	1021	1279	75.9
9	156Gd(p,2n)155Tb	8	900	668	836	92.9

Productions 3 and 6 were excluded due to technical failures of the separation panel. To calculate the separation yield, the EOS activity was corrected to EOB time considering the decay correction (sixth column) and then used to calculate the fraction of initial activity recovered after the separation
