Abstract

Water radiolysis is a major concern for the conditioning of radioactive waste in cement materials. Synthetic calcium silicate hydrate (CSH), the main hydrates of concrete, were synthesized with different C/S ratios and relative humidities. The samples were irradiated under γ- and electron beam irradiation. The radiolytic hydrogen production has been quantified and the radiation induced defect produced at low temperature characterized by electron paramagnetic resonance. The results show that the H production and defect production are only marginally sensitive to the relative humidity
