In this study, the alterations in viscoelastic and aggregation parameters of red blood cells were analyzed for usualgamma irradiation procedures for transfusion purposes. In order to determine possible hemorheological changes thatmay affect the health of patients and their relationship with the biochemical changes observed, the blood samples wereirradiated at different doses. The results show alterations in the erythrocyte aggregation time, in the membrane surfaceviscosity and in the size of the aggregates in the irradiated samples, suggesting that the damage produced by the ionizingradiation affects the physical properties of red blood cell membrane at different levels.
