Radiation as a Tool against Neurodegeneration-A Potential Treatment for Amyloidosis in the Central Nervous System.

Using it for disorders involving cell loss is counterintuitive. However, ionizing radiation has a hormetic nature: it can have deleterious or beneficial effects depending on how it is applied.
