Table 1. Summary of G-Values for the Loss of Ligand from the Irradiation of Deaerated 1.5 M DEHBA or DEHiBA in 6.0 M HNO₃ Pre-Equilibrated n-Dodecane solution in the Absence and Presence of Uranium or Rhenium under Envisioned Direct Dissolution Conditions.

system	G-value (μmol J^–1)
1.5 M DEHBA/n-dodecane (cobalt-60)	0.38 ± 0.03^a
1.5 M DEHBA/n-dodecane (electron beam)	0.30 ± 0.01^a
1.5 M DEHBA/n-dodecane + 0.35 M uranium (cobalt-60)	0.18 ± 0.01
1.5 M DEHBA/n-dodecane + 100 mM rhenium (electron beam)	0.31 ± 0.02
1.5 M DEHiBA/n-dodecane (cobalt-60)	0.36 ± 0.01^a
1.5 M DEHiBA/n-dodecane (electron beam)	0.29 ± 0.05^a
1.5 M DEHiBA/n-dodecane + 0.35 M uranium (cobalt-60)	0.24 ± 0.01
1.5 M DEHiBA/n-dodecane + 100 mM rhenium (electron beam)	0.33 ± 0.04

The slight discrepancies between cobalt-60 and electron beam results are attributed to insufficient solution mixing at the VdG beamline. However, the observed trends are internally consistent.
