Measurement of the ratio beweeen the short-lived radon daughters and $sup 210$Pb in order to determine the aerosol residence time in the troposphere is discussed. It is concluded that the various residence time values obtained experimentally with radioactive elements make it possible to determine parameters representing the processes of vertical exchanges and of scavenging which prevail on a large scale in the troposphere, thus making it possible to use numerical models of simulation for calculating the tropospheric residence time of any other element.
