Description
Summary:The radiation tolerance is a critical concern in nuclear waste host materials due to the decay of constituent radioactive elements. In order to evaluate the effect of beta irradiation on ceramic waste forms, the bulk SrTiO 3 ceramic was subjected to 1.8 MeV of electron irradiation and characterized by X-ray diffraction, Raman spectroscopy and field scanning electron microscope, respectively. The dose rate was compared between electron irradiation and decay of 90 Sr. The results indicated that the as-prepared ceramic exhibits excellent resistance to electron radiation. The pristine crystalline form was retained after 1.8 MeV electron radiation. Also no noticeable change was observed in the measured elements distribution of the irradiated sample. The results indicated that the irradiation damage via beta decay is imperceptible in ceramic solids.
