The oxidation processes of crude and preliminary radiation-oxidation processes in the environment of hydrogen peroxide of zirconium during radiation exposure on zirconium-water system have been studied by the reflection-absorbed IR-spectrometry method. It is carried out the comparison of their kinetic peculiari- ties. The passivation process of metal surface is revealed and it is confirmed the presence of surface oxide layer on the basis of kinetic of radiation oxidation in the contact of preliminary processed zirconium with water.
