Aerosol Properties and Unattached Fraction of Radon Daughters Close to the Human Face

Abstract
A humanoid dummy inside a well controlled radon exposure chamber (volume=20m3) was used to investigate the properties of an aerosol close to, and far away from the human face, respectively. Rn222 and a NaCl aerosol (geometric mean diameter=86 nm, concentration ( 5000 cm-3 was added to the room. The size distribution of the passive aerosol and the unattached fraction of the radon progeny were measured in one sampling point during two different conditions: (1) with the face of the dummy close to the sampling point and (2) with the dummy placed 3 m from the sampling. The measured parameters show no significant difference in the two sampling situations, so it seems to be possible to characterise the inhaled air by measuring far away from the... (More)
