A. Vargas et X. Ortega, The influence of non-uniform particle deposition on the Po-218 diffusion coefficient measured with the "two-filter" method, J AEROS SCI, 32(11), 2001, pp. 1389-1395
The influence of non-uniform Po-218 density distribution on the downstream
filter was estimated on the basis of a numerical analysis of the aerosol pa
rticle transport inside a tube and of a numerical estimation of the efficie
ncy for alpha radioactive particle detectors. For published diffusion coeff
icients of 0.103, 0.067 and 0.045 cm(2) s(-1), the error was found to be +2
0%, +25% and +26% respectively, compared with a uniform deposition. (C) 200
