²³⁵U Aerosols Particle-Size Distribution

The particle-size distribution of 235U aerosols was measured by the solid tracks detective technique. The aerosols samples were gathered onto a metal plate by the static electricity dust sampler. The radiograph of any α radioactive particles was carried out in the solid tracks detective sheet, which was imaged, developed and magnified with the chemical etched technique. The relative parameters were measured on the optical microscope. Finally, 235U aerosols particle-size distribution under specific condition is 1.6-8.9 mm.
