High-penetrating gamma-rays (Co-60) have been mainly used as an external radiation in irradiation experiments on water radiolysis for the 1F decommissioning, 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 films having a good penetrating property for their radiations to measure H
and its geminate product of HO as radiolysis products of water.

The overflow from HIC at ALPS was owing to water radiolysis of beta rays in co-precipitate slurry of carbonate, leading to the volume increase of slurry and supernatant formation. The radiation effects (radiolysis and material degradation) on high-viscous fluids after long-term (high dose) irradiation is quite different from those on low-viscous fluids such as aqueous solutions. The understanding of effects on high-viscous fluids, containing suspension of clay which is planned to be used as a buffer material for final disposal, is important in long-term storage and disposal of radioactive wastes. In this study, the physical and viscosity properties of fluids of co-precipitate and clay systems were measured before and after irradiation of electron beam and gamma ray to discuss the relations among their properties quantitatively.
