213Bi activities of sample 3 (see Table 1) containing 213Bi in SEq with 225Ac and an added amount of 213Bi. GC measurements were performed at different time-points before and after SEq between 213Bi and 225Ac using the \({\text{EW}}_{{213_{{{\text{Bi}}}} }}\). Error bars represent the standard deviation provided by the GC software
