background: the study of rheological properties of blood has special interest since it is a circulating fluid exposed to shear rates during its life time. this work aims to investigate the influence of whole body gamma irradiation on the rheological properties of rat’s blood. the applied shear rate was from 12 to 375 s-1. low shear viscosity (up to 100 s-1) depends mainly on the erythrocytes ag...
