✦ Synopsis
High-dose gamma irradiation of electrodes provided with an active film consisting of 5 mol. % RuO, and 95 mol. y0 TiO, may produce electrodes whose chlorine overvoltage at 60°C in a solution containing 3COg NaCl per dm' conforms to the relation r/ = 0.44 + 0.190. log i (V; A/cm*) for i e (0.04; 1.5).
A @'Co source and doses about 4.9 _ 10' C kg-' (1.9 GR) were used. The gamma radiation has a positive effect of short duration in that it decreases the chlorine overvoltage, especially at higher cds. In the course of time the chlorine overvoltage ofirradiated electrodes will increase beyond the values obtained with untreated eIectrodes.
