The aim of the presented work was to investigate the stability of biocompatible magnetic fluid, i.e. water-based magnetic fluid containing magnetite nanoparticles stabilized by surfactant sodium oleate and modified by bovine serum albumin (BSA) after electron irradiation. Samples with the same concentration of Fe_{3}O_{4} but different mass ratio BSA/Fe_{3}O_{4} (w/w=0.25, 1.0 and 2.5) were studied. The electron irradiation caused about 10% reduction of the saturation magnetization in the samples with w/w BSA/Fe_{3}O_{4} ratio of 0.25 and less than 5% in the samples with w/w BSA/Fe_{3}O_{4} ratio of 1 and 2.5.
