Fig. 5

Pseudo-recovery curves (ICF values in cps/MBq as a function of cylinder volumes) for: 131I (red circle), 133Ba (purple star), 133Ba cross-calibrated (cc) using the theoretical emission probabilities ratio (green square), and 133Ba cross-calibrated using the experimentally measured setup-specific factors from Table 4 (blue cross). Note that each pair of subplots in a row has different scales in the y-axes
