Hydrolysis of Water (5)

H2O (molecule) + ionizing radiation → H+ + OH = (hydroxyl,  free radical)
Recombination of:
 H+ + H+ → H2 = hydrogen gas (not a problem)
 H+ + OH → H2O = water (not a problem)
Antioxidants can recombine with the OH free radical and  block hydrogen peroxide formation. If not, then the 2  hydroxyl ions could do the following:
 OH + OH → H2O2 = hydrogen peroxide formation
 H2O2 → H+ + HO2− = unstable peroxide
 HO2− + organic molecule → stable organic peroxide
 Stable organic peroxide → lack of essential enzyme → eventual cell death is possible
