High-penetrating gamma-rays (Co-60) have been mainly used as an external radiation in irradiation experiments on water radiolysis for the 1F decomissioning, while the experiments using electron beams (EB) simulating beta-rays (Sr-90 and others) and X-rays simulating the bremsstrahlung of electrons have been also expected. However these are difficult because of the low-penetrating property of radiations. In this study, the experiments using EB and X-rays were conducted by using reaction vessels sealed with a film having a good penetrating for their radiations to measure H2 and its geminate product of H2O2 as radiolysis products of water.
