Radon Decay Product Aerosols in Ambient Air

  title={Radon Decay Product Aerosols in Ambient Air},
  author={Constantin Papastefanou},
The aerodynamic size distributions of radon decay product aerosols, i.e. Pb, Pb, and Pb were measured using low-pressure (LPI) as well as conventional low-volume 1-ACFM and high-volume (HVI) cascade impactors. The activity size distribution of Pb and Pb was largely associated with submicron aerosols in the accumulation mode (0.08 to 2.0 μm). The activity median aerodynamic diameter “AMAD” varied from 0.10 to 0.37 μm (average 0.16 μm) for Pb-aerosols and from 0.07 to 0.25 μm (average 0.12 μm… CONTINUE READING
