Glasses used for nuclear waste immobilization are subjected to high levels of radiation, and this may affect their physicochemical properties. Alpha radiation is responsible for an important fraction of the radiation energy dissipated in these glasses. It has been reported previously that some borosilicate glasses increase their density during irradiation while the density of other glasses decreases. Although the density increase of silica after irradiation has been understood, thanks mainly to molecular dynamics calculations and diffraction ...
