Relationship between deposition and attachment rates in Jacobi room model.

It is shown in this work that parameters of the Jacobi model, which describes behavior of short-lived radon progeny, are not independent. The relationship between deposition rate of attached radon progeny and attachment rate of their unattached fraction was determined in this paper. It was found that deposition rate increases when the attachment rate is smaller; this effect is more pronounced for larger friction velocity. The deposition rate of attached radon progeny is presented here as a function of friction velocity, ventilation and attachment rate. Deposition rate of attached fraction was estimated in the range 0.012-0.46 h(-1), when attachment rate varies from 10 h(-1) to 100 h(-1). Copyright (c) 2010 Elsevier Ltd. All rights reserved.
