  During the past decay many experimental configurations to improve the yield
of hydrogen by electrolysis. These attempts include tests of different
materials for the electrodes. This study proposes the use of {\gamma}-radiation
of waste sources of nuclear reactors. The related experimental configuration
can be reduced to boxes filled with water exposed to ionizing radiation and
capacitors as electrodes as well-known in other technical disciplies. Test
measurements based on radiation of a linear accelerator (6 MV beam) provided
significant differences of the yield of hydrogen between with and without
radiation.
