摘要：
An analytical model of the emanation of radon 222 from individual aerosol particles by direct recoil and diffusion processes is presented The net rate of arrival of radon atoms at the particle boundary is treated as an effective generation rate. Analytic expressions for the overall fractional release are derived for short and long times. Re-interpretation of existing experimental data using this analysis leads to ''second generation'' estimates of the diffusion coefficients.
