Аннотация: This chapter is an overview of main processes and effects in cementitious materials which occur under the exposure of ionizing radiation. The information provided should be useful for regulators and waste managers since it shows the possibility of extending the application of such materials in immobilization of not only intermediate-level waste, but also some types of high-level waste. Cementitious materials are known to be used in nuclear industry for a long time to construct facilities exposed to high irradiation doses (pools for spent nuclear fuel, nuclear research and power reactors, high-energy particle accelerators, hot cells, high-level waste dry casks, medical facilities using nuclear systems and X-rays, etc.). These materials are convenient for immobilization of different types of liquid and solid radioactive waste. However, currently cements can be only used as matrices for low- and intermediate-level waste. This is due to the doubts about their stability toward higher radiation doses. The main results of radiation damage are typically mechanical weakening, release of hydrogen gas, and cracking that can lead to the destruction of the matrix and enhanced release of radionuclides in contact with groundwater. In this chapter, we have overviewed main effects of ionization radiation on cementitious materials and on applicability of such materials as immobilizing materials suitable for radioactive waste of higher activities.
