The particle size distribution of radioactive aerosols after the Fukushima accident

Popis výsledku v původním jazyce

After the Fukushima accident the aerosol particle size distribution associated with the radionuclides released from the NPP was investigated (the time period from 24th March to 13th April 2011). The samplings were carried out by 5 stage cascade impactorson collection substrates placed on individual stages and on the back-up filter. Gamma spectrometric analysis using HPGe detectors was performed to determine the activities of radionuclides on each collection substrate from individual stages and on the back-up filter. The obtained spectra contained mainly 131I, 134Cs and 137Cs, their aerosol activity concentrations were determined. The values of activity concentrations of 131I, 134Cs and 137Cs corresponding to different aerodynamic diameters of the aerosol were used to evaluate the particle size distribution mainly in terms of the activity median aerodynamic diameter (AMAD) and its geometric standard deviation (GSD).The total activity concentrations of 131I were in the order of magnitud
