Table 3 Reactions that could possibly form O2 from other reactive oxygen species

From: Importance of radiolytic reactions during high-LET irradiation modalities: LET effect, role of O2 and radiosensitization by nanoparticles

Reaction number Reaction Rate constant (M−1 s−1)
(1) \( {\text{HO}}_{2}{ \cdot } {\text{~ + ~HO}}_{2}{ \cdot } {\text{~}} \to {\text{~H}}_{{\text{2}}} {\text{O}}_{{\text{2}}} + {\text{~O}}_{2} \) 9.7 × 107
(2) \( {\cdot\text{OH + HO}}_{2} \cdot \to {\text{H}}_{2} {\text{O + O}}_{2} \) 6.0 × 109
(3) \( {}_{{}}^{{}} {\cdot \text{OH + H}}_{ 2} {\text{O}}_{ 2} \to {\text{H}}_{2} {\text{O + HO}}_{2} \cdot \) 2.7 × 107
