Fe3O4 nano-particles have been successfully prepared by EB irradiation with two different actived agents, Polyvinyl alcohol (PVA) and Polyethylene glycol (PEG), at room temperature and ambient pressure, without any kind of catalysts. The optical properties, component and morphology of the irradiated samples were measured by Ultraviolet-visible spectrophotometer (UV-vis), X-ray diffraction (XRD) and Transmission electron microscopy (TEM). The size of nano particles was found to be affected by the action of the different actived agents.
