摘要：

The impact of alpha -radiolysis on the corrosion potential of a UO//2 electrode has been measured in an electrochemical cell designed to bring a gold-plated alpha -source to within 30 mu m of the electrode. A potential of plus 70 mv (SCE) was obtained in the presence of a 686 mu Ci alpha -source, indicating the establishment of oxidizing conditions. Over 30 h the main process occurring appeared to be catalytic decomposition of hydrogen peroxide to water and oxygen. Oxidation of UO//2 also occurred, but the extent remains to be established.
