This work investigated the irradiation behavior of gray desert soil holding simulated An 4+ waste under an irradiation of 1.5 MeV Xe 20+ to fluences from 1 × 10 12 to 1 × 10 15 ions cm − 2 . The results indicated that the structure has no obvious change due to irradiation fluences and waste load. The normalized leaching rate of Ce after 28 days of the MCC-1 test is in the order of 1 × 10 − 5 g cm − 2  d − 1 before and after irradiation. This work identifies gray desert soil, which has good radiation resistance, as a potential matrix for solidification tetravalent actinides. Graphic abstract
