Colloidal Behavior of Plutonium in Groundwater-bentonite System Simulated under Disposal Conditions

Yuanzineng kexue jishu
Plutonium is a highly toxic transuranic element in high-level radioactive waste. Because of the variety of species of plutonium, it has a serious potential to migrate to the ecological environment in the process of deep geological disposal.
