Determination of parameters of the Jacobi room model using the Brownian motion model.

Parameters of the Jacobi room model were estimated with simulation of Brownian motion. Deposition on internal room surfaces and attachment of progeny atoms to three modally distributed aerosols were taken into account. The values of parameters were presented as functions of aerosol concentrations. The deposition rate of an unattached progeny was estimated in the range 30-47 h-1; the deposition rate of an attached progeny was very small and its range is 0.0007-0.004 h-1; the attachment rate of a progeny is in range 40-170 h-1. The statistical uncertainty was lower than 1%. The ranges of parameters were similar to those reported in literature.
