One of the species generated in water or aqueous solutions by the ionizing radiations are free electrons that quickly become "hydrated" or "aqueous electrons" (see for example this or this), and it is said that this is a chemically reactive species (reducing agent).
But the body can get charged with static electricity apparently with no harmful effect (for example here). In case of getting negatively charged, does the extra electrons also forms hydrated electrons? Are they equally reactive? If not, why not?
