Atomic structure of irradiated materials is more akin to liquid than glass

Materials exposed to neutron radiation tend to experience significant damage, leading to the containment challenges involved in immobilizing nuclear waste or nuclear plant confinements. At the nanoscale, these incident neutrons collide with a material’s atoms that, in turn, then collide with each other somewhat akin to billiards. The resulting disordered atomic network and its physical properties resemble those seen in some glassy materials, which has led many in the field to use them in nuclear research.
