The effects of α‐radiolysis on leaching were studied in compositionally identical Pu‐doped waste glass samples which were prepared at different α‐activities (dose rates) by varying the 239 Pu/ 238 Pu isotopic ratio in the Pu dopant. The results of 14‐, 28‐, and 56‐d static leach tests at 40°C, in both deionized water and brine solution, indicate that α‐radiolysis at the samplelsolution interface increased Pu and Si release by a factor of ≅3.
