Size-distribution of airborne radioactive particles from the Fukushima accident

Abstract

The particle size distribution of radioactive aerosols, which originated from the released radioactive materials from the Fukushima Daiichi nuclear power plant accident, has been observed using the Andersen-type classifier combined with a high volume air sampler. Estimated activity median aerodynamic diameters (AMADs) of 131I-, 134Cs- and 137Cs-aerosols were ranging from 0.56 to 0.60 μm, which were larger than that of 7Be-aerosols existing as an aerosol including cosmogenic radionuclide, about 0.2 μm.
