| Uranium-adsorbed silica particles were prepared as a reference material for the fission track analysis of swipe samples. A modified instrumental set up for particle generation, based on a commercial vibrating orifice aerosol generator to produce various sizes of droplets from a SiO2 solution, is described. The classification of the silica particles in the range from 5 mm to 20 mm was carried out by the gravitational sedimentation method. The size distribution and morphology of the classified silica particles were investigated by scanning electron microscopy. The physicochemical properties of the classified silica particles such as the surface area, pore size and pore volume were measured. The silica particles were coated with 5 % 235U in mixed polymer solution (5 % poly vinyl pyrrolidinone and 5 % poly ethylenemine acetic acid). The various sizes of uranium-adsorbed silica particles were applied to the fission track analysis for use as a reference material. |
