[en] Adult male rats, weighing 150 ± 10 gm, were irradiated with different doses (4.32, 36, 70 and 140 mSv) of fast neutrons from a 241Am-Be source. The blood samples were withdrawn from the heart by cardiac puncture 24 hours post irradiation and the rheological properties of whole blood were studied immediately at 37 deg C by means of Brookefield DV-III rheometer. The consistency index, the yield stress, the apparent viscosity and flow index were determined. The exposure to fast neutrons resulted in a decrease in the whole blood viscosity as well as its yield stress as a function of dose. The osmotic fragility test revealed significant decrease after 4.32 and 36 mSv, which increased after the exposure to 70 and 140 mSv. The damaging effect of fast neutrons on the rbcs membrane was also investigated by the membrane solubilization test using 1 % Triton-X solution as detergent. (author)
